Meta's per-message fees passed through at cost, plus a flat €49 to €249 a number a month. No changelog, official SDK or standalone OpenAPI download.

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.

Before you call either

360dialog WhatsApp API + MCP

  1. Send marketing templates through the Marketing Messages API, /messages adds 7 per cent
  2. Ask a docs page a question with ?ask= before reading the whole page
  3. Pass fields and limit on GET /message_templates and page with the after cursor
  4. Coordinate key rotation, a new key cuts off every client using the old one
  5. Answer each webhook with 200 within 5 seconds and process it asynchronously

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
