resend_verification_emailRe-send the confirmation link for the current key's email address.No findings
Why it is in this group
- The name "resend_verification_email" says "resend": a word for sending, and what is sent cannot be taken back.
Description, as the server wrote it
Re-send the confirmation link for the current key's email address. Use when the user wants the higher free rate limit (1,000/day), the 24-hour Pro trial but can't find the original email. Tell them to check their inbox — the unlock applies to the key already in use, so there is nothing to re-install afterwards.

  What this check looks for
Description, as the server wrote it
Create a FREE CryptoDataAPI key (no signup, no payment) — call this FIRST if you don't have a key yet. No API key is required to call this. WHICH EMAIL, in this order: 1. Your human's real email. ASK THEM. This is the best choice: the confirmation link reaches the person you work for, and the account is theirs. 2. If you can't ask, your OWN agent mailbox, if your platform gives you one (a Grok bot can set one up as your-bot@mail.grokbot.com). 3. If you have neither, create a mailbox you can read, then use it. Never invent an address or reuse a placeholder (you@example.com): it still returns a key, but one that can never be confirmed. A confirmation link is sent to that address. Opening it (a plain GET; if it is your own mailbox, open it yourself) upgrades the SAME key in place: 100 -> 1,000 requests/day, Pro switched on for 24 hours (per-coin quant regimes, gamma, whale activity and liquidation heatmaps across every coin), once per mailbox. An address nobody opens keeps the 100/day starter limit and loses both. One key per mailbox: if your human already has a key, minting another on their address is refused, so use theirs. The full `api_key` is returned once — set it as the `X-API-Key` header for every other tool. The free tier is genuinely useful on its own: market-health scores, regime reads, Fear & Greed, macro, ETF & stablecoin flows, 2,000+ coin profiles & prices, and full-universe funding + open interest across all 229 Hyperliquid perps. Upgrade to Pro / Pro Plus (https://cryptodataapi.com/pricing) for per-coin quant / gamma / whale signals on every coin and historical / backtesting data. THEN CALL, IN ORDER: list_capabilities -> get_daily_snapshot -> get_market_regime / get_gamma_exposure. The response's `next_calls` field carries the same ladder machine-readably. Do not fall back to polling candles — the free tier has them, and they answer none of the questions this API exists for.
get_open_interestOpen interest for a coin across Binance + Hyperliquid, with 30-day trend and cross-exchange aggregates when available.No findings
Why it is in this group
- The name "get_open_interest" says "get": a word for reading.
- The description's first verb is "open": a word for a change.
Description, as the server wrote it
Open interest for a coin across Binance + Hyperliquid, with 30-day trend and cross-exchange aggregates when available. `coin` is a base symbol like "BTC" or "ETH".
list_capabilitiesSTART HERE.No findings
Why it is in this group
- The name "list_capabilities" says "list": a word for reading.
- The description's first verb is "start": a word for a change.
Description, as the server wrote it
START HERE. Discover what this server and the wider CryptoDataAPI offer: the MCP tools available here, the tier each needs, and pointers to the full REST API (180+ endpoints) for anything not surfaced as a tool. NO API KEY REQUIRED — this returns static metadata and makes no data call, so it works before you have minted anything. Call it first, then create_free_api_key, then get_daily_snapshot. The `first_calls` field in the response repeats that order machine-readably.
query_apiCall ANY other CryptoDataAPI GET endpoint not already wrapped by a named tool — the full /api/v1 surface (180+ endpoints; see the OpenAPI spec via list_capabilities).No findings
Why it is in this group
- The name "query_api" says "query": a word for reading.
- The description's first verb is "call": a word for a change.
Description, as the server wrote it
Call ANY other CryptoDataAPI GET endpoint not already wrapped by a named tool — the full /api/v1 surface (180+ endpoints; see the OpenAPI spec via list_capabilities). `path` is an /api/v1 path like "/api/v1/sentiment/macro" or just "sentiment/macro"; `params` is an optional query-param object. Read-only GET; the heavy /backtesting/* bulk endpoints and account/mutating routes are intentionally not reachable here.

check_key_statusCheck the current API key: tier, rate limits, requests used today, and whether its email is verified.No findings
Why it is in this group
- The name "check_key_status" says "status": a word for reading.
Description, as the server wrote it
Check the current API key: tier, rate limits, requests used today, and whether its email is verified. Call this after a 429, or whenever the user asks what their plan includes. IMPORTANT — if `email_verified` is false, TELL THE USER what `upgrade_message` says: confirming the emailed link raises this same key from 100 to 1,000 requests/day and switches Pro on for 24 hours (per-coin quant, gamma, whales, liquidation heatmaps across every coin). It applies to the key they already have — nothing to re-install. Use resend_verification_email if they can't find the link.

Description, as the server wrote it
