  title: Anansi Data Free API
  description: 'Pay-per-call access to accumulated time-series and derived analytics that no one else archives: prediction-market history, LLM price-change and deprecation records, per-minute cross-chain gas, perp funding, and a live index of paid agent endpoints.


    Payment uses x402: every paid route answers 402 with a signed challenge naming price, asset and payTo BEFORE any charge, so a client can decide before it commits. Settlement is USDC on Base mainnet.


    Each dataset carries an explicit licence tag. Sources granting no redistribution right for raw values are served as derived analytics only; a dataset whose terms have not been reviewed fails closed rather than open. Paid responses carry provenance naming source and method.'
