  2. Stay under 300 API requests per 5 seconds, a 429 carries no Retry-After

  4. Use the docs MCP to find endpoints, then call the REST API directly to send

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.
