AgentLine gives AI agents real US phone numbers, inbound/outbound voice calls, A
AgentLine gives AI agents real US phone numbers, inbound/outbound voice calls, AI receptionists, transcripts, inbound SMS and live phone events. Use REST or MCP without signup: recharge and save agent_token. This endpoint adds prepaid credit with Base USDC x402 or Tempo MPP. $1 minimum recharge; numbers $2/30 days; connected calls $0.10/min (first-minute minimum, then per-second); inbound SMS $0.02. Other endpoints use prepaid balance and do not accept payments.
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.
