Register a webhook so your AI agent receives real-time monitor events

Push delivery for event-driven agents (Claude, OpenClaw, Hermes, or any HTTPS service): we POST a signed event to your endpoint the moment a monitored account posts (tweet.new), replies, retweets, or quotes — so your agent reacts in real time instead of polling. A terminal monitor.expired / monitor.deleted event fires once when a monitor ends, so silence is never ambiguous. Free (SIWX). Your HTTPS endpoint receives a signed POST for every event from every monitor this wallet owns (optionally filtered by eventTypes). VERIFY EVERY DELIVERY: recompute sha256=HMAC-SHA256(secret, ${X-Twitr-Timestamp}.${rawBody}) and constant-time-compare against the X-Twitr-Signature header; reject timestamps older than 5 minutes; dedupe on the envelope's delivery_id (per retry) and id (per event). Respond 2xx within 10 seconds — do slow work async. Delivery envelope: {type, id, delivery_id, monitor_id, occurred_at, received_at, source, data}. Retries back off over ~36 minutes (max 6 attempts) before marking the delivery failed; 50 consecutive failures auto-pause the webhook (a successful /test re-activates it). Max 3 webhooks per wallet.
