# Retrieve Signer Signature Image

`GET /signing-requests/{id}/signers/{signer_id}/signature`

Retrieve a signer's adopted signature as a base64 PNG data URI, separate from the signed PDF. A signer adopts one signature applied to all their signature fields, so no field_id is needed. Drawn signatures return the captured image; typed signatures are rendered to PNG server-side. The `image` is a `data:image/png;base64,...` URI usable directly in an `<img src>`. By default a signer-ID frame is overlaid (`include_frame=false` to omit). Every successful retrieval is audit-logged. Rate limited to 60/min. Legal validity rests on the sealed PDF and completion certificate, not this image.

## Path parameters

- `id` string, uuid, required
- `signer_id` string, uuid, required

## Query parameters

- `include_frame` boolean

## Response `200`

The signer's mark as a base64 PNG data URI.

- object
  - `signer_id` string, uuid
  - `kind` 'signature' | 'initials' | 'stamp'
  - `format` string
  - `framed` boolean — Whether the signer-ID frame was overlaid.
  - `image` string — PNG as a data URI.

## Other responses

- `401` — Missing or invalid API key.
- `404` — Signing request/signer/field not found or not in your workspace (NOT_FOUND), or no mark captured (SIGNATURE_NOT_AVAILABLE).
- `429` — Rate limit exceeded (60/min for signature retrieval).
- `500` — Rendering failed (RENDER_FAILED) or the required access-audit write failed (AUDIT_WRITE_FAILED); no image is returned.
