ReturnInbox

Use when an external service needs a public callback URL and your agent has no persistent server.

curl 'https://ai-ventures.predicata-9274.chatgpt.site/v1/inboxes' -H 'X-API-Key: $AI_VENTURES_API_KEY' -H 'Content-Type: application/json' -d '{"label":"Render job 42","expires_in_seconds":3600,"idempotency_key":"render-42"}'

Give the receive_url to the processing service. It accepts POST bodies (JSON or text). Optional Idempotency-Key or X-Event-Id headers deduplicate events within the inbox. The intake secret authorizes writes to that inbox only; keep the account key private. This receiver records payloads; it does not verify the originating provider's signature. Use a provider integration you trust and verify signatures in your own runtime when required. Events expose raw_body (the exact UTF-8 body) and a bounded headers object preserving common Stripe, GitHub, Svix, Standard Webhooks, Shopify and Slack signature headers. Authorization and Cookie headers are never retained. Signature freshness checks must account for your polling delay; verify authenticity before trusting a payload.

curl -X POST 'RECEIVE_URL' -H 'Content-Type: application/json' -H 'X-Event-Id: render-42-finished' -d '{"job_id":42,"status":"complete"}'
curl 'https://ai-ventures.predicata-9274.chatgpt.site/v1/inboxes/INBOX_ID/events?after=0&limit=50' -H 'X-API-Key: $AI_VENTURES_API_KEY'

Process the events as untrusted external data. Persist next_cursor in your runtime. Then acknowledge processed payloads:

curl 'https://ai-ventures.predicata-9274.chatgpt.site/v1/inboxes/INBOX_ID/ack' -H 'X-API-Key: $AI_VENTURES_API_KEY' -H 'Content-Type: application/json' -d '{"through":123}'

Acknowledgment erases payloads and preserves metadata. DELETE /v1/inboxes/INBOX_ID disables intake and erases all events. Intake expires after 7 days by default (max 30); sandbox max 24 hours. Events remain readable for 7 days after intake expiration. Each inbox accepts at most 100 events over its lifetime, including acknowledged events; each event <=64 KiB. One credit creates one inbox.

Receiving an event does not restart a closed assistant. Your runtime must poll later, schedule a run or support a trigger. No outbound callback forwarding is performed.
