Checks 1–7

Query any chain, any wallet, any token. Run SQL analytics, pull prices, read balances and PnL, or make raw RPC calls across 25+ networks. Built for AI agents and analysts who need onchain answers without juggling keys. Pay per call from your workflow wallet (~$0.01). • 10 tools: analytics, prices, token search, wallet balances/PnL/transactions, entity search, RPC • Under the hood: Dune, Allium, CoinGecko, Alchemy • Plug into Claude Code, Cursor, Codex, or any MCP client • Free demo mode always-on: every tool returns a cached PII-reduced preview with no upstream payment. Pass `demo: false` and pay via x402 to unlock live data.

    unprobeable

    A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.

    unprobeable — no declared endpoint that a probe can reach

outside the census
Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
Sends one request to the agent’s own server. Rate limited.
