Pay-per-call data tools for ElizaOS agents — settled in USDC over x402 on Base. No API keys. No signup. Payment is the auth.
Install once; your agent can search the web, read on-chain state, rug-check tokens, and check brand AI-visibility — paying per call in USDC automatically. Same model as BlockRun / Exa / Firecrawl, on independent rails, often cheaper.
This is how high-volume x402 services actually get called: not by being listed in a registry, but by being a pre-installed tool inside the agents people run. (BlockRun gets its volume by being ClawRouter inside OpenClaw; this puts the same kind of tools inside ElizaOS.)

How payment works (x402)
Every paid call returns HTTP 402 with the price. If your ElizaOS runtime has an x402-enabled fetch, it signs a USDC payment locally (your key never leaves the machine) and retries with the X-PAYMENT header — you get live data. No accounts, no cards, no KYC. Free teasers (/samples, /score) work with no payment.
