How this service works
Re-check up to 5 tokens you hold or watch in one call, on Base, Ethereum, Arbitrum, Optimism, Polygon or Solana: each token's 0-100 risk score, level, reason codes, price, liquidity and a fingerprint. Send the fingerprints back as since to get what changed (new risks, owner or authority changes, liquidity or price moves of 10%+) and a short list of alerts. One price for the whole list, made for polling positions on a schedule. Rules-based, not advice.
Output
Returns an array of per-token objects each containing: a 0-100 risk score, a risk level label, an array of reason codes explaining the risk, current price, liquidity, and a fingerprint string. Also returns a short list of alerts for any tokens where the fingerprint (since) indicates something changed — new risk codes, ownership or authority changes, or price/liquidity moves of 10% or more.
Example use cases
DeFi portfolio daily risk scan
“Run a risk check on these three tokens I hold — base:0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, eth:0xdAC17F958D2ee523a2206206994597C13D831ec7, arbitrum:0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC2 — and tell me their risk scores, levels, and any reason codes flagged.”
Watchlist change detection since last poll
“Poll my token watchlist for what changed since my last check — tokens are solana:EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v and base:0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, and here are the fingerprints from the last call: abc123,def456. Show me any alerts about new risks, liquidity drops, or authority changes.”
Pre-trade multi-chain token safety check
“Before I buy, quickly check the risk scores and liquidity for these two tokens — optimism:0x7F5c764cBc14f9669B88837ca1490cCa17c31607 and polygon:0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 — and flag anything that looks dangerous.”
Technical details
Endpoint
GEThttps://onchaincheck.dev/watchlist?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to monitor or risk-check multiple tokens (up to 5) in a single low-cost call, especially for scheduled polling of a watchlist. The fingerprint/since delta mechanism makes it ideal for agents that need to detect changes since the last poll without reprocessing unchanged data. Prefer this over single-token endpoints when managing a portfolio or watchlist across multiple chains simultaneously.
Side effects
- Invalid or malformed chain:address pair returns an error for that token slot
- More than 5 tokens in the tokens parameter results in a validation error
- Mismatched number of fingerprints vs tokens in the since parameter causes a mismatch error
- Unsupported chain identifier returns an error indicating valid chains
- Address not found on the specified chain returns a not-found result for that token
- Payment failure (x402) if the $0.01 USDC payment is not provided or rejected
