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.

Telnyx API + MCP

US long code SMS $0.004 a part outbound and inbound, published with carrier fees and as machine-readable pricing.md. No per-key scopes or read-only keys, and the MCP can send or buy numbers without confirmation.

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.

Telnyx API + MCP

  1. Register the 10DLC brand ($4.50) and campaign ($10 a month) before sending US long code traffic
  2. Back off on error 10011 for as long as the Retry-After header says
  3. Call get_api_endpoint_schema before invoke_api_endpoint, the schemas aren't in the tool list
  4. Give each agent its own key, since keys can't be scoped
  5. Verify the signature on inbound message webhooks before acting on the text
