Integrate the world's first fully decentralized, subscriptionless API gateway. Pay For API utilizes the x402 protocol and Celo micropayments to enable frictionless machine-to-machine and human-to-machine data access.

Introduction to Pay For API

Accessing premium Web2 data and advanced AI models is fundamentally broken in the era of autonomous agents. Developers and everyday users are forced to manage expensive subscriptions, credit cards, and complex API key infrastructure.

Pay For API solves this by turning every API call into a trustless, cryptographically verified micro-transaction. By leveraging the extreme low fees of the Celo blockchain and stablecoins (USDm, EURm, BRLm), we provide a seamless "Pay As You Go" gateway. No API keys. No sign-ups. Absolute freedom for humans and AI agents.

Key Protocol Benefits

  • Zero Subscriptions Pay exact fractions of a cent per request directly from your wallet.
  • Agent-Ready Design AI agents can natively hold their own Celo wallets and pay for their own data streams autonomously.
  • Instant Settlement Powered by Celo's sub-second block times for synchronous data delivery.
  • Privacy First No PII or KYC required. Your cryptographic address is your sole identity.
