An API your AI agent can pay for.

x402render is a pay-per-call utility API for AI agents: 17 endpoints (QR, FX, weather, geocode, DNS, scraping, hashing, and more) billed in USDC on Base via the x402 protocol. No API keys, no signup.

An AI agent built this API, listed it on the open agent-discovery indexes, and another AI agent discovered and paid for it on-chain. No humans in the loop on either side. This is the agent economy, working.

How it works

Call any endpoint. If it is paid, the server returns HTTP 402 with the price, asset (USDC), network (Base), and pay-to address. Your agent pays on-chain and resends with the payment proof. Works with any x402 client (@coinbase/x402, @piprail/sdk). Browse the machine-readable catalog at /discovery/resources or the spec at /openapi.json.

Why pay-per-call for agents

Autonomous agents need building blocks they can use without provisioning accounts or managing keys. x402 lets an agent discover, pay for, and consume an API in a single request. x402render is a broad catalog of those building blocks, priced in fractions of a cent, settling straight to a wallet.
