Hey Ada — your order is on the way. Carrier UPS, ETA Wednesday.
Wij zijn een team van engineers die graag tools bouwen voor andere engineers.
Test mode, real-time webhooks, and an MCP server for the agent on your shoulder.
Testmodus. Simuleer elke status — afgeleverd, gebounced, klacht, in wachtrij — zonder echt budget te verbranden of een echte ontvanger te bereiken.
Modulaire webhooks. Real-time event webhooks, per channel. email.delivered, sms.failed, voice.completed, whatsapp.read. HMAC-signed. Replay-protected. Same shape every channel.
MCP voor agents. Connect Claude or Cursor to Bird's hosted MCP server, or run it locally with the bird CLI. Your agent gets typed tools across every channel — scoped keys, full audit, no leakage.
Vijf producten.
Eén gedeelde laag.
Email, SMS, voice, WhatsApp, and Realtime — all built on the same primitives. Learn the platform once, ship across every channel.
Auth. One key format. Scoped to send vs. manage, read vs. write. Prefix + fingerprint so you know which key did what. Multiple keys live at once, so you rotate on your schedule.
Idempotency. Idempotency-Key on every POST, PATCH, and DELETE. Replays come back free and flagged. Reuse a key with a different body and you get a 409, not a surprise.
Errors. One envelope. One closed type union. Every code ships with a docs link and a message that tells you what to do.
Webhooks. Standard Webhooks spec: HMAC-SHA256, per-endpoint secrets, 5-minute replay window — verify with any off-the-shelf library. Rotate secrets with a 24-hour dual-signing overlap. Attempt logs and replay built in.
Paginering. Cursor-based. Stable order on every list, enforced by construction — no page drift, ever.
Rate limits. IETF RateLimit headers on every response — not just the 429. You can see your budget before you hit the wall, and Retry-After when you do.
Suppressions. Bounces, complaints, unsubscribes — managed automatically, queryable and editable via API. Transactional streams can bypass marketing unsubscribes. Idempotent by design.
