List signers GET

Use this endpoint to review users and services registered in the system. Find signers by handle (typically an email, username, or service name), public key, or key format. Supported filters: - `data.public` — public key - `data.format` — key format - `data.schema` — signer schema - `meta.status` — record status - `meta.labels` — record labels - `meta.domain` — domain scope - `data.custom.<field>` — any custom field (may be slower on large datasets)

Update signer PUT

The request must include the current record hash in `data.parent` to prevent conflicts from concurrent updates. If the parent hash does not match the record's current hash, the request is rejected with a 422 error. Broadcasts the `signer-updated` signal. Use [effects](/ledger/reference/api/effect) to subscribe.
