  title: CoinGraph Decide API
  version: 1.0.0
  summary: 'Provable crypto data for AI agents: market, on-chain, whale, contract and sanctions data in one call.'
  description: 'Humans read it, agents call it. Every response carries where the data came from (sources) and when it was true (as_of); anything unmeasured is "unassessed". CoinGraph never executes, custodies or advises — the caller decides.


    Phase: hackathon. Discover and Trust calls are free. Data calls (state, history, market) are free for 25 calls a day, then 1 credit. Premium calls (sized checks, fresh briefs, questions, address lookups, monitors, most agents) are 5 credits; Pro agents are 25. With an API key, calls spend credits; without one, paid calls answer 402 with x402 payment details.'
