## Verdicts

**Telegram Bot API.** Telegram's first-party bot interface is free, needs no card and documents 185 methods on one page with a dated changelog and numeric send limits. No OpenAPI document, status page, SLA or idempotency key was found, one token controls the whole bot and travels in the URL, and a person must create the bot in a chat with @BotFather.

**Twilio API + MCP.** Per-segment US prices, carrier fees by carrier and the $0.001 failed-message fee published without a login. US SMS at $0.0083 a segment plus $0.0035 to $0.005 in carrier fees, with inbound charged at the same rate.

## Before you call either

### Telegram Bot API

1. Send `POST https://api.telegram.org/bot<token>/sendMessage` with `chat_id` and `text`. Keep the token out of logs, because it is part of the URL.
2. On HTTP 429 wait the `parameters.retry_after` seconds before retrying. Stay under one message a second per chat and 20 a minute per group.
3. Call `getUpdates` with `offset` set to the last `update_id` plus one, or the same updates return. Updates are kept for at most 24 hours.
4. A retried send can post twice, as there is no idempotency key. Record the returned `message_id` before retrying after a timeout.
5. In groups the bot sees only commands and replies unless privacy mode is disabled in @BotFather or the bot is an admin.

### Twilio API + MCP

1. Use the hosted docs MCP to find the endpoint, then call the REST API with a restricted API key
2. Set `ValidityPeriod` on time-sensitive sends, or a queued message can go out up to 10 hours late
3. Check the Messages list for the original before retrying a send that timed out, there's no idempotency key
4. On a trial account, send only to verified numbers in the sign-up country using Twilio's message templates, custom bodies aren't available until you upgrade
5. Validate `X-Twilio-Signature` on every inbound webhook
