@rileycraig/plugin-x402-agentstore

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.)

npm install @rileycraig/plugin-x402-agentstore

import x402AgentStore from "@rileycraig/plugin-x402-agentstore";
// add to your ElizaOS character's plugins: [ x402AgentStore ]

What your agent gets

| Action | What it does | Price (USDC) | |---|---|---| | WEB_SEARCH | One call → Hacker News + GitHub + Stack Overflow + Wikipedia, unified & ranked | ~$0.004 | | WIKIPEDIA_LOOKUP | Fast factual grounding | ~$0.001 | | ONCHAIN_BALANCE | Native + ERC-20 balance, any address, 6 chains | ~$0.001 | | ONCHAIN_GAS | Live gas price, 6 chains | ~$0.001 | | ONCHAIN_TX_STATUS | Tx status + receipt by hash | ~$0.001 | | TOKEN_SECURITY_CHECK | Pre-trade rug check (honeypot, tax, mint/owner risk) | ~$0.002 | | DEX_TOKEN_DATA | Live DEX price / liquidity / flow | ~$0.002 | | TOKEN_LAUNCHES_FEED | New & trending token feed for sniping agents | ~$0.003 | | AI_VISIBILITY_CHECK | Does ChatGPT/Perplexity recommend a brand? (unique) | free teaser / paid | | AI_CATEGORY_RANKING | Which brands AI recommends in a category | ~$0.02 |

Cheaper than the field: WEB_SEARCH bundles 4 sources for ~$0.004 vs Firecrawl's $0.01/search; on-chain reads from $0.001.

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.

Trust & verification (check us before you pay)

• Live store: https://store.agentexchange.work — /status, /healthz, free /samples of every product.
• Discovery: A2A agent card at /.well-known/agent.json, x402 catalog at /.well-known/x402, full /openapi.json, MCP at /mcp.
• On-chain proof: every payment is a public USDC transfer on Base → 0xc91cE6291eDC0713ec753BAFBA002506ffb2b95c (audit on BaseScan).
• Indexed: Coinbase x402 Bazaar + x402scan.
