    ElizaOS plugin: pay-per-call data tools over x402 (USDC on Base, no API key). WEB SEARCH (Hacker News + GitHub + Stack Overflow + Wikipedia in one call) for research/coding/grounding agents, ON-CHAIN READS (wallet balance, gas, tx status across Base/Ethereum/Optimism/Arbitrum/Polygon/BSC), a trading lane (token rug-check, live DEX data, new-token feed), and unique AI-visibility/GEO data.

    Readme

    @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.
