## Findings

- **warn** Annotations that disagree with the tool in `network.prepare_transfer` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "network.prepare_transfer" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "network.prepare_transfer" says "transfer": a word for a change that another call does not undo.
```

- **info** Long descriptions in `places.lookup` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 4,001 characters long, over the 2,000 this check looks for.

description ends: "...same arguments plus `paymentPayload` to complete payment and get the real result."
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `network.prepare_transfer`

- The name "network.prepare_transfer" says "transfer": a word for a change that another call does not undo.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Build an **unsigned** native or token transfer transaction for a supported chain, from an explicit sender you provide. Free, read-only against the chain (nonce/gas/fees are read live) — this tool never signs, broadcasts, holds a key, or enforces any allowlist/spend limit. This server never binds a caller wallet, so `from` is always required.

Supported chains: solana, solana-devnet, ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia.

Token (`token` field):
- Solana: 'SOL' (native, default) or 'USDC'.
- EVM: native symbol (default), 'USDC', 'USDC.e' where configured for the chain, or a raw 0x contract address (decimals are read live from the contract; `token_decimals` is only a fallback if that read fails).

Gas: the sender pays gas in the chain's native token once they sign — this server never sponsors it.

Raw calldata (EVM only): pass `data` (hex, 0x-prefixed) with `to` as the contract call target and `amount` as the native value to send (use "0" for a pure call).

Privacy (`private`, EVM only): requests SKALE BITE encryption, only supported on skale-base-sepolia, where it defaults to true — pass `private: false` there for a plaintext transfer. Rejected on every other chain.
```

## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `market.crypto`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Crypto market-data lookups (CoinGecko-sourced pricing and market data), paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`:

- search ($0.001): fuzzy-search coins by name/symbol. Requires `q`. Call this first to resolve a coin id before using price_feed or historical_data, both of which need an id (e.g. "bitcoin"), not a ticker.
- price_feed ($0.001): current price (and optionally 24h change / market cap) for one or more coins. Requires `ids` (comma-separated coin ids). Optional `currencies` (comma-separated fiat codes, default "usd"), `include_24h` (default true), `include_mcap` (default false).
- market_data ($0.002): coins ranked by market cap (or another order) — use for "top N coins" / market overview questions. Optional `currency` (default "usd"), `category`, `order` (default "market_cap_desc"), `limit` (1-250, default 100), `page` (default 1).
- historical_data ($0.003): historical price/market cap/volume series for one coin. Requires `id`. Optional `currency` (default "usd"), `days` (lookback window or "max", default 30), `interval` (e.g. "daily").
- trending ($0.001): currently trending coins by search interest. No extra parameters.
- token_prices ($0.005): DEX-derived prices for up to 200 tokens in one call. Requires `tokens`, an array of `{chain, token_address}` objects.

Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
```

### `weather.forecast`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Weather data from a global weather data provider — current conditions, short-range forecast, astronomy, historical, marine, and location search. Free, read-only, no wallet needed. Every action requires `q`, a location: a city name (e.g. "Paris"), "lat,lon" (e.g. "48.85,2.35"), a US/UK/Canadian postal code, or an IATA airport code. Pick one `action`:

- current: current conditions for `q`. Optional `aqi` (default false) adds basic air quality data.
- forecast: forecast for `q`. Optional `days` — this deployment runs on a data plan capped at 3 days, so only 1-3 is accepted; omit for the provider default. Optional `aqi`, `alerts` (default false, adds active weather alerts for the location where available).
- astronomy: sunrise/sunset/moonrise/moonset/moon phase for `q` on `date` (required, YYYY-MM-DD).
- search: resolve a fuzzy `q` into matching locations (name, region, country, lat/lon) — use this first if you only have an approximate place name and need to disambiguate.
- history: past weather for `q` on `date` (required, YYYY-MM-DD, must be yesterday). This deployment enforces a free-tier data plan that only allows yesterday's date — any other date is rejected before a provider call is made.
- marine: marine/sailing conditions for `q`. This deployment runs on a data plan limited to 1 day of data with no tide information.

Results are for general informational purposes only — do not use them as the sole basis for decisions involving personal safety, aviation, marine navigation, or emergency planning.
```

## Only reads (9)

Looks things up and changes nothing. Claude Code: allow.

### `network.blocknumber`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the current chain head — EVM block number or Solana slot — for a supported network. Free, read-only, no wallet needed.

Use this to confirm a network is progressing before submitting a transaction, correlate off-chain events with on-chain height, or choose a safe starting point when scanning logs.

Pass `chain` as one of: solana, solana-devnet, ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia. Omit `chain` (or pass `all`) to query every resolvable chain in one call.
```

### `network.gas_info`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the current gas price and EIP-1559 fee hints for an EVM chain. Free, read-only, no wallet needed.

Use this to estimate transaction cost or explain fees to a user before they send a transaction. `chain` is required. Supported chains: ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia.
```

### `network.token_info`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read ERC-20 token metadata — name, symbol, decimals, total supply — for a token contract on an EVM chain. Free, read-only.

Pass `token` as a contract address (0x…) or symbol `USDC` / `USDC.e` on chains where a lookup is configured. This server never holds a caller wallet, so no balance is ever returned — only public token metadata. Both `chain` and `token` are required. Supported chains: ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia.
```

### `network.token_price`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a spot token price from a public market API (CoinGecko). Free — no payment or wallet needed. Defaults to ETH/USD.
```

### `network.transaction_status`

- The name "network.transaction_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check the status of a transaction. Supports both EVM (transaction hash) and Solana (signature). Free, read-only.

Use this to confirm a transfer landed, debug a failed transaction, or report status to a user. Both `chain` and `transaction_hash` are required. Available chains: solana, solana-devnet, ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia.
```

### `places.lookup`

- The name "places.lookup" says "lookup": a word for reading.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Places, solar, and aerial-view lookups, paid per call directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`:

- text_search_full ($0.08): full-detail place text search. Requires `textQuery`. Optional `maxResultCount` (1-5, default 5), `excludeFields` (default ["photos"]), `pageToken`, `locationBias` ({circle:{center:{latitude,longitude},radius}}), `includedType`, `languageCode` (default "en"), `openNow`, `minRating` (0-5), `priceLevels`.
- text_search_partial ($0.02): same as text_search_full but returns fewer fields per place — cheaper for quick lookups. Same parameters.
- nearby_search_full ($0.08): full-detail search for places within a radius. Requires `locationRestriction` ({circle:{center:{latitude,longitude},radius (0-50000)}}) — do NOT send a bare top-level latitude/longitude/radius. Optional `includedTypes`/`excludedTypes` (max 50 each), `maxResultCount` (1-5, default 5), `excludeFields` (default ["photos"]), `languageCode` (default "en"), `rankPreference` (POPULARITY default, or DISTANCE).
- nearby_search_partial ($0.02): same as nearby_search_full, fewer fields, cheaper. Same parameters.
- place_details_full ($0.05): full details for one place. Requires `placeId` — the exact place id returned by an earlier text_search/nearby_search result; do not invent or guess it. Optional `excludeFields` (default ["photos"]), `languageCode` (default "en").
- place_details_partial ($0.02): same as place_details_full, fewer fields, cheaper. Same parameters.
- solar_building_insights ($0.02): rooftop solar potential for one location. Requires `latitude` (-90..90) and `longitude` (-180..180). Optional `requiredQuality` (LOW/MEDIUM/HIGH, default HIGH).
- solar_data_layers ($0.08): raw solar data layers for an area. Requires `latitude`, `longitude`. Optional `radiusMeters` (0.1-175, default 50), `view` (default "FULL_LAYERS"), `requiredQuality` (default HIGH), `pixelSizeMeters` (default 0.25, documented as one of 0.1/0.25/0.5/1.0 but not schema-enforced), `exactQualityRequired` (default false).
- solar_rgb_image ($0.05): renders one of the solar_data_layers assets as a viewable image. Either `id` (the exact asset id already returned by an earlier solar_data_layers call — "Mode A"; do not invent or guess it) OR both `latitude` and `longitude` ("Mode B") is required — provide exactly one mode, not both. Optional `radiusMeters` (0.1-100, default 30, Mode B only), `layer` (default "rgb"), `month` (1-12), `hour` (0-23), `format` (png/jpeg, default png), `scale` (1-2, default 1), `crop` (default false), `quality` (1-100, default 85).
- aerial_view_lookup_video ($0.01): check whether a rendered aerial-view video already exists / poll its render status. Exactly one of `address` or `videoId` is required — `videoId` must be the exact value returned by an earlier aerial_view_render_video call; do not invent or guess it.
- aerial_view_render_video ($0.01): kick off rendering a new aerial-view video for an address. Requires `address`. Poll aerial_view_lookup_video with the returned videoId until ready.

Pagination: text_search_full/partial and nearby_search_full/partial return `nextPageToken` when more results exist — repeat the ORIGINAL call (same textQuery / locationRestriction / etc.) with `pageToken` set to page further. `pageToken` must be the exact `nextPageToken` value from that earlier response — do not invent or guess it.
excludeFields: colon-separated nested-path syntax trims nested response fields, e.g. "organization:technologies" excludes just that sub-field. All place-search/details actions default-exclude `photos` if `excludeFields` is omitted — pass `excludeFields: []` to include photos.

Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result… [1 more characters not shown]
```

### `social.profile_lookup`

- The name "social.profile_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve person / social-profile identity for a batch of records, paid per call directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Supports two modes per record:

- Fuzzy match: supply `first_name` and/or `last_name` plus `emails` and/or `phones`.
- Reverse lookup: supply only `emails` and/or `phones`, no name required.

Every record needs a caller-chosen `record_id` (any string) to correlate it with its match in the response, plus at least one non-empty first_name/last_name, or at least one non-empty entry in emails, or at least one non-empty entry in phones — an empty array counts as not provided. Optional top-level `match_condition_fields` (e.g. `["linkedin_url"]`) restricts results to matches that include ALL of the named fields.

The exact response shape (field names/nesting per match) is passed through unchanged from the upstream provider — read whatever comes back rather than assuming a fixed shape.

Charges ~$0.02 per call — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
```

### `travel.search`

- The name "travel.search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Flight and hotel search, paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`:

- flight_search ($0.02): live flight fares via Google Flights. Requires `origin`, `destination`, `departureDate`. Optional `returnDate`, `adults`, `children`, `travelClass`, `stops`, `maxPrice`, `currency`.
- hotel_search ($0.02): live hotel prices/ratings via Google Hotels. Requires `q` (city or hotel name), `checkInDate`, `checkOutDate`. Optional `adults`, `children`, `sortBy`, `minPrice`, `maxPrice`, `hotelClass`, `currency`.

Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
```

### `web3.lookup`

- The name "web3.lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Multi-chain wallet, token, ENS, and transaction-simulation lookups, paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`:

- wallet_balances ($0.005): token balances for a wallet across 20+ chains. Requires `chain` and `address`.
- wallet_transactions ($0.005): transaction history with asset transfers for a wallet. Requires `address`. Optional `chain`, `limit`.
- wallet_pnl ($0.01): realized and unrealized profit/loss per token for a wallet. Requires `chain` and `address`.
- token_metadata ($0.002): name/symbol/decimals for a token contract. Requires `chain` and `address`.
- ens_resolve ($0.001): resolve an ENS name to an Ethereum address. Requires `name`.
- ens_reverse ($0.001): resolve an Ethereum address to its ENS name. Requires `address`.
- tx_simulate ($0.01): simulate an EVM transaction before sending — gas estimate, execution trace, revert reason. Requires `network_id`, `from`, `to`. Optional `value`, `data`, `gas`.

Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
