A real response from the API; long lists are cut to their first items.

`p` is the liquidity-weighted YES mid of the included venues (fees not included); `venues[].excluded` says why a quote was left out (`stale`, `one_sided`, `crossed`, `wide`). The method is in [Consolidated prices](https://langbot.ai/docs/consolidated). A measurement, not advice.

## Errors

| Status | `code` | When |
|---|---|---|
| 401 | `token_invalid` | A token was sent and not recognised. Send a valid one, or none to call anonymously. |
| 422 | `validation_error` | A parameter failed validation; `detail[].loc` names it. |
| 429 | `rate_limited` | Over your request budget; wait `Retry-After` seconds. |

Every error body is `{"detail": …, "code": "…"}`; branch on `code`. All codes: [Errors](https://langbot.ai/docs/api#errors).
