  summary: Pay-per-call APIs for AI agents, settled in USDC on Base, Solana or Polygon, or RLUSD on the XRP Ledger, with x402.
  description: 'Pay-per-call APIs for AI agents, paid in USDC on Base, Solana or Polygon, or RLUSD on the XRP Ledger, with x402: web search, page fetch and extract, PDF to text, an HTTP proxy, and crypto market data. No signup or API key.


    On Base, you only pay for a successful response; errors are not charged except where an operation says so (for /api/tx-status, a not_found status is a charged answer; poll again after pollAgainSeconds). These no-charge statements are made for USDC on Base. On USDC on Solana, and RLUSD on the XRP Ledger, a refused or failed request may still be charged. charged: false means Horizon Pulse did not settle the payment; on USDC on Solana, and RLUSD on the XRP Ledger, this is not a guarantee that no funds moved. Every paid operation carries `x-payment-info` with the exact price, asset, network and payTo of its Base entry; these match the 402 challenge and https://horizonpulse.dev/.well-known/x402. The 402 challenge also offers the same price in USDC on Solana mainnet (`exact`, network solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp, USDC mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, payTo BjY98A6dS3GGLZdz2zHy8wK7XAwnQgNhCc66mfmBTRPz, PayAI facilitator https://facilitator.payai.network), and in native USDC on Polygon PoS mainnet (`exact`, network eip155:137, USDC 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359, payTo 0x5b32c973596078a967562ca652761404f19be0e9, facilitator: Coinbase CDP), and in RLUSD on the XRP Ledger mainnet (`exact`, network xrpl:0, currency RLUSD = 524C555344000000000000000000000000000000, issuer rMxCKbEDwqr76QuheSUMdEGf4B9xJ8m5De, payTo r3FbirL83RAB2CwnUdxE5pCohMkuo6LQcf, verified on the validated ledger).
