title: Annalist Dev Sample API
version: 0.9.0
x-guidance: 'Annalist sells signed data for agents, priced per call over x402 (USDC on Base or Solana). Start with the free GET /v1/catalog: every paid route with the question it answers, its price and an example. Hyperliquid in one call: GET /v1/perp/full?coin=BTC (crowd state, smart-money positioning, liquidation levels). Before paying an x402 service: GET /v1/checks/service?host=, or the free GET /v1/verify/attestation?host=. Before connecting an MCP server: GET /v1/mcp/server?url=, or the free GET /v1/verify/mcp?url=. Before an agent shops on a site: the free GET /v1/verify/store?domain=, or GET /v1/web/readiness?domain=. Every answer is Ed25519-signed; the key is at /.well-known/annalist-key.json. Not investment advice.'
