Verdicts

Bird API + MCP

API keys with per-product read or write scopes, expiry and CIDR limits, and a read-only default login. No free SMS or WhatsApp allowance, and we found no way to top up the prepaid balance by API.

Photon

Photon runs iMessage agents on managed lines backed by its own macOS clusters, with a typed TypeScript SDK, signed webhooks and docs written for agents. Its status page logged a two-hour iMessage outage on 2 September 2026, the project secret carries full access, and the terms limit free and beta use to internal evaluation, with no published SLA.

Before you call either

Bird API + MCP

  1. Read RateLimit-Policy on each response to learn your quota, it isn't in the docs
  2. Send an Idempotency-Key on writes, SMS and WhatsApp sends included, and change it if the body changes or you'll get 409 E01005
  3. Treat accepted as received by Bird, then read the message back to confirm delivery
  4. Connect to mcp.bird.com/dynamic if your client struggles with large tool lists
  5. Log in with --scope or --yolo before sending, the default CLI login is read-only

Photon

  1. Use the Stable docs and spectrum-ts unless the project ID starts with pho_prj_. Stable and Beta packages, hosts and credentials don't mix
  2. Design flows so the person texts first. Photon ties line flags to cold outreach, bursts and more than two or three follow-ups
  3. Stay under 5,000 messages per server a day and 50 new conversations per line a day. Further sends are rejected until the window resets
  4. Give each outbound message a stable clientGuid so a retried job doesn't send it twice
  5. Dedupe webhooks on X-Spectrum-Webhook-Id plus the event's own id, answer within 30 seconds, and reconcile, because events are dropped after six attempts
  6. Keep the project secret out of the agent's context. It grants full management access and doesn't expire
