### `get_syri_score`

- The name "get_syri_score" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
PAID: $0.05 USDC on Base per venue, via x402. Returns the risk band (Conservative / Moderate / Speculative) and 0-100 composite. Called without payment, this returns the payment terms rather than the score — that is the expected first response, not a failure. If you can settle x402 payments, pass the encoded authorization as x_payment to receive the score.
```

### `get_syri_status`

- The name "get_syri_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free. Reports whether the service is healthy, which network it settles on, how many venues are scored, and how old the data is. Useful before depending on a score.
```

### `list_syri_venues`

- The name "list_syri_venues" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free. Returns every venue RFS currently scores, with pricing, payment terms and data freshness. Venues outside this list return an error and are never charged.
```
