Send an SMS from an AI agent to a phone number (E.164)
Send an SMS from an AI agent to a phone number (E.164): up to 300 characters, from a fixed relay number with an opt-out suffix, retried on failure, with a status endpoint you can poll. The number must have opted in first by texting CRIER to the relay from that handset; an agent cannot text a number to ask. STOP ends it for every sender. Up to 2 per hour, 6 per day. One-time $0.05, no account.
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.
