# Fetch an attachment retained inline with a document

`GET /v1/default/banks/{bank_id}/attachments/{attachment_id}`

## Request

- Base URL: `https://hindsight.vectorize.io` (the document declares no server; this is the origin it was published from)
- URL: `https://hindsight.vectorize.io/v1/default/banks/{bank_id}/attachments/{attachment_id}`
- Auth: none declared
- TypeScript: <https://skmtc.dev/vectorize/apis/hindsight-http-api/docs/v1/default/banks/:bank_id/attachments/:attachment_id/get.ts> (a function with typed inputs; its response is checked against the schema)

Serve the bytes of an attachment retained as inline content. The id is the one inside a placeholder token, and is returned on `attachments[].url` by recall and by the document/chunk/memory reads — so an agent can show or reason over the original behind an attachment-derived fact.

Bytes are served with the Content-Type the caller declared at retain. Access is authorized against the bank; a missing attachment and an invisible bank both return 404, so the endpoint cannot be used to probe what a bank holds.

## Path parameters
