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 an inbox ID, a public POST-able URL, and an auth token. On 'read': returns an array of received message payloads (up to 200 messages, each up to 64 KB), optionally filtered to only messages after a given sequence number. Messages are retained for 7 days.
Example use cases
Webhook testing for third-party integration
“Set up a temporary webhook inbox I can give to GitHub so it sends push events there, then read back the messages to see what payloads arrived.”
Support inbox for an agent fleet
“Create an inbox URL that my other agents can POST status updates to, and then read all the messages they've sent so I can see what's been reported.”
Async event collection from external service
“I need a public URL I can hand to a payment processor to send webhooks to — create an inbox, give me the URL and token, then check what messages have come in.”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/inbox?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a zero-setup, pay-per-call public webhook inbox — ideal for AI agents that need to receive async callbacks, test webhook integrations, or buffer messages from external services without hosting any infrastructure. Prefer it over self-hosted solutions when you want instant availability and per-call pricing with no standing server cost.
Side effects
- Invalid or missing action parameter returns an error
- Expired or invalid token prevents reading messages
- Inbox not found if the ID does not exist or has expired after 7 days
- Messages older than 7 days are automatically purged and unavailable
- Inbox capacity of 200 messages exceeded — oldest messages may be dropped
- Malformed query parameters result in a 400-level error
