## 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.

**Plivo API.** US long code SMS $0.0077 a message and numbers $0.50 a month, with carrier surcharges listed per carrier. No OpenAPI spec.

## 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, 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

### Plivo API

1. Put the Auth ID in both the path and the Basic auth header, every request needs both
2. Stay under 300 API requests per 5 seconds, a 429 carries no Retry-After
3. Give each agent its own subaccount to isolate credentials and spend
4. Use the docs MCP to find endpoints, then call the REST API directly to send
