How this service works
x402 pay-per-call. Payments are per request in USDC and are final. No refunds on-chain. Service is provided as-is and may change or stop without notice. Informational data only, not financial, investment, legal, or tax advice. Metrics such as net transfer volume estimates and wallet clusters are algorithmic estimates from public blockchain data and may be wrong or delayed. Provided as-is with no warranty. Methodology: https://crypto-data-api-zo95.onrender.com/methodology.
Output
Returns a JSON object with a summary string, an array of findings (each flagged or not), a slippage estimate for a $10,000 buy, transfer volume metrics (gross, non-circular, circular estimates), and a disclaimer. Fields include checks_run (list of check IDs and whether they were flagged), transfer_volume object with non_circular_share_estimate, and generated_at_utc timestamp.
Example use cases
Token due diligence before investing
“Before I buy into this new DeFi token at 0x6B175474E89094C44Da98b954EedeAC495271d0F, can you run an on-chain market check and tell me if there are any suspicious circular trading patterns or red flags?”
Slippage check for large trade
“I'm about to buy $10,000 worth of the token at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 — can you check what the estimated price impact would be and whether the volume looks legitimate on-chain?”
Screening token for a DeFi dashboard
“I'm building a watchlist and need an on-chain health summary for the token 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — does the transfer volume look organic, or is there a lot of circular or bot activity?”
Technical details
Endpoint
GEThttps://crypto-data-api-zo95.onrender.com/v1/token/market-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call on-chain health check for a specific ERC-20 token, including circular/wash trading estimates and slippage impact, without committing to a subscription. Best for ad-hoc due diligence or agent workflows that need token risk signals on demand.
Side effects
- Missing or malformed token address (not matching ^0x[0-9a-fA-F]{40}$) returns a validation error
- Token address not found on-chain returns empty or null findings
- Payment not completed via x402 results in 402 Payment Required response
- Service may be unavailable or return stale data without notice as it runs on Render free tier
- Algorithmic estimates may be wrong or delayed — not guaranteed accurate
