Field notes

The listed workflow moves from a POST to /v1/send to key provisioning and a wallet purchase; separate endpoints cover balance, available packs, and message status. For agent discovery, the page points to a machine-readable skills index and an llms.txt guide, and names an MCP package with send_sms and create_api_key tools. Its credit examples are denominated in USD.
