# Get a receipt

Source: https://langbot.ai/docs/api/receipts/get-receipt

`GET /v1/receipts/{evt_id}`

One event with its hash, its position in the source's chain and the nearest signed checkpoint.

**Auth.** None. Without a token the call is served as Free (the Free delay and request budget, shared per IP); send `Authorization: Bearer lb_…` for your plan's.

**Limits.** Counts against your plan's API requests (60, 600 or 3,000 a minute on Free, Builder and Standard). Served at your plan's delay (+60 s Free, +10 s Builder, +2 s Standard).

## Parameters

### Path parameters

|---|---|---|---|

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

`verified` is the feed recomputing the stored hash; verify it yourself offline with the SDKs ([Receipts and replay](https://langbot.ai/docs/receipts#verifying-offline)).

## Errors

| Status | `code` | When |
|---|---|---|
| 404 | `not_found` | Unknown id, or the event is still inside your plan's delay. |
| 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).
