How this service works
Ephemeral capture inbox for autonomous agents. Create a one-time ingest URL; anything POSTed to it (OAuth redirect, async job result, third-party webhook) is captured and held for you to poll. Bridges external pushes into pollable events for agents that have no public endpoint.
Output
Returns an ephemeral ingest URL that external services can POST to; any payload received at that URL is captured and held, accessible via polling. Typically includes the inbox URL and a token or identifier for retrieving the captured payload.
Example use cases
OAuth callback capture for agent
“I need a temporary URL to act as my OAuth redirect URI for a GitHub authorization flow — create an ephemeral inbox that captures the redirect and holds it for me to poll.”
Stripe webhook capture without server
“Set up a one-time ingest URL I can give to Stripe as a webhook endpoint — catch the payment event payload and hold it until my agent is ready to read it.”
Async job result collection
“I've kicked off a long-running background job on an external API that will POST results when done — create a capture inbox URL I can register as the callback so I can poll for the result later.”
Technical details
Endpoint
POSThttps://nodeproxy-production.up.railway.app/agent-inboxWhen to prefer
Choose this endpoint when your agent needs to receive an inbound push event (OAuth redirect, webhook, async callback) but has no persistent public endpoint of its own. Ideal for ephemeral agent workflows where you need to bridge a one-time external push into a pollable event without standing up infrastructure. Prefer over persistent webhook services when you only need a single-use capture with no long-term storage requirements.
Side effects
- Inbox URL expires before the external system posts to it — payload is lost
- External service sends a GET instead of POST — may not be captured correctly
- Payload exceeds size limits — request rejected
- Polling too late after TTL expiry — captured event no longer available
- Invalid or missing arguments object in request — malformed inbox creation
