No OpenAPI spec.\n\n## Before you call either\n\n### ClickSend SMS API + MCP\n\n1. Call calculate-sms-price before a bulk send, the pricing endpoint needs no key\n2. Pass the user's own date words in user_date_request when reading SMS history\n3. Use a subaccount key for the agent, not the main account key\n4. Restrict access to the MCP host's log files, they contain the encoded API key\n5. Leave links out of messages, ClickSend pauses SMS with URLs for new customers\n\n### Plivo API\n\n1. Put the Auth ID in both the path and the Basic auth header, every request needs both\n2. Stay under 300 API requests per 5 seconds, a 429 carries no Retry-After\n3. Give each agent its own subaccount to isolate credentials and spend\n4.
