How this service works
Crypto market data, DeFi analytics, and x402 ecosystem intelligence via pay-per-request USDC on Base mainnet.
Output
Returns a JSON object with: paid (bool), found (bool), grade (letter grade like 'A-'), address (the queried address), trust_score (integer 0-100), and recommendation (e.g. 'SPEND' or 'AVOID').
Example use cases
Example prompt
“Before I pay, can you check the Crest trust score and grade for this x402 service address 0x1234567890abcdef1234567890abcdef12345678 and tell me if I should spend USDC on it?”
Technical details
Endpoint
GEThttps://data.crestsystems.ai/data/service-trust/%7Baddress%7DWhen to prefer
Use this endpoint when an AI agent needs to vet an x402 service receiver address before authorizing a USDC payment on Base mainnet — specifically when you want a letter grade, numeric trust score, and a binary SPEND/AVOID recommendation rather than raw on-chain data. Prefer this over generic wallet analytics when operating within the x402 pay-per-request ecosystem.
Side effects
- Address not found in x402 registry — found: false returned
- Invalid address format (not EVM 0x+40hex or Solana base58) — likely 400 error or empty result
- Payment not processed — 402 response if USDC payment fails
- Unknown or very new address with no activity — low trust_score with limited data
- Network/service downtime — 5xx error
