Ephemeral webhook receiver for agent and SaaS integrations. Create a single-use HTTPS URL, point any sender (Stripe, GitHub, cron — anything that POSTs) at it, then read the captured events back. Ingest is free and always answers 200; you only pay to read and to extend.

Endpoints

POST /webhook_catch        $0.05 — create hook, body: {"ttl_minutes":60}
POST /hook/<id>            free  — sender-side ingest (always 200)
POST /hooks/<id>/events    $0.01 — read captured events, optional {"clear":true}
POST /hooks/<id>/extend    $0.05 — +1h on the TTL
DELETE /hooks/<id>         free  — early delete

How it works

1. Create a hook with your agent wallet → get hook_url + id (in-memory, TTL default 1h, range 5min–24h).
2. Deliver: give hook_url to any real sender. Events are stored capped at 100 per hook and auto-deleted at expiry.
3. Read with {"clear": true} to pop events in one call.
