## Verdicts

**ClickSend SMS API + MCP.** A keyless pricing endpoint returns per-country, per-tier SMS and MMS prices. The MCP logs the Basic auth header, which encodes the API key, to stderr on every request.

**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.

## Before you call either

### ClickSend SMS API + MCP

1. Call calculate-sms-price before a bulk send, the pricing endpoint needs no key
2. Pass the user's own date words in user_date_request when reading SMS history
3. Use a subaccount key for the agent, not the main account key
4. Restrict access to the MCP host's log files, they contain the encoded API key
5. Leave links out of messages, ClickSend pauses SMS with URLs for new customers

### 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.
