What an agent can call

Five endpoints, settled in USDC on Solana mainnet. You pay only when the call succeeds.

  • certsTLS certificate check — $0.002
  • heartbeatCreate an uptime monitor — $0.003
  • pixeldriftLaunch page captures — $0.005
  • bundleBundle check — $0.008
  • topupPrepaid credit — from $0.008

How it works

The x402 protocol (HTTP 402) — your agent pays in the same request.

  1. 1

    Your agent calls an endpoint and receives a 402 challenge with the price and payment address.

  2. 2

    It signs the payment in USDC and resends the request. Gas is sponsored — your agent needs only USDC, not SOL.

  3. 3

    The service runs, and the payment settles only if the call succeeds.

Built for agents

No sign-up, no secrets, no friction.

No account, no API key — just a funded wallet.

Gas sponsored — USDC only, no SOL management.

Pay only on success — a failed call is never charged.
