How this service works
Webhook inbox: create an inbox and get a public URL any service can POST to (free to send), then read the received messages with your token. Keeps 200 messages, 64 KB each, for 7 days. Also callable as GET with the same fields as query parameters.
Output
On 'create': returns a public inbox URL and an auth token used to read messages later. On 'read': returns the list of messages (up to 200) that have been POSTed to the inbox, optionally filtered to messages after a given sequence number. Each message can be up to 64 KB and is retained for 7 days.
Example use cases
Capture webhooks from third-party service
“Set up a public inbox URL I can paste into Stripe's webhook settings to capture payment events, then read back what Stripe has sent so far.”
Support inbox for an agent fleet
“Create a webhook inbox my worker agents can POST status updates to, then read all the messages they've sent since the beginning so I can see what they've reported.”
Testing incoming webhook payloads
“I need to quickly test that my app is sending the right webhook payload — can you create a temporary public URL to receive the POST, then read back exactly what was sent?”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/inbox?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent or workflow needs a temporary, zero-setup public URL to receive incoming HTTP POST payloads from any external service — particularly useful for testing webhooks, capturing events from third-party platforms, or enabling agent-to-agent communication without standing up any server infrastructure. Prefer it over persistent message queues when short-lived retention (7 days, 200 messages) is sufficient and simplicity matters.
Side effects
- Missing 'action' query parameter — request is rejected
- Invalid or expired token when reading — access denied or empty result
- Inbox ID not found or expired after 7 days — 404 or empty message list
- Message store full (200-message limit) — oldest messages may be dropped
- Malformed request body on POST to inbox — message may not be stored correctly
