Chat-id routes
Chat-id progress
Poll processing progress for a Deep Reader chat.
GET
Get document progress
Snapshot of processing status for a Deep Reader chat. For the attachment-id SSE, use Progress stream.
Authorizations
Organisation API key from Settings → API / /api/keys/. The secret is
shown once. Send Authorization: Bearer sk-abacus-…. One active key
per organisation. Ingest (/api/v2/ingest/*) refuses API keys — that
surface is Auth0-only with ingest:read / ingest:write scopes.
Path Parameters
Response
Processing status snapshot for the progress-polling endpoint.
Serializes ChatAttachment directly (not Chat) because the progress endpoint queries the attachment by chat pk.
