Send one SMS to a mobile number, paid per message in USDC with x402
Send one SMS to a mobile number, paid per message in USDC with x402. Use it when an agent must notify a person by text. The 402 quotes the exact price for the destination and message length. No account and no API key: any wallet that pays sends in one call. An opt-out link is appended to the message, and numbers that opted out are refused. Returns an order; poll GET /v1/orders/{id} for delivery status.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
