How this service works
Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.
Output
A JSON object with an 'ok' boolean, a 'mode' string (e.g. 'token'), a 'report' object containing a 'verdict' field (e.g. WATCH, SAFE, DANGER), and a 'product' label ('pons_filter'). When no token is supplied, returns a recent-scan stub instead.
Example use cases
Pre-trade token risk check
“Before I swap into this token at 0xabc123... on Base, can you run it through the Pons filter and tell me if it comes back as SAFE, WATCH, or DANGER?”
Automated DeFi portfolio screening
“I have a list of token addresses from my DeFi portfolio — can you run each one through the Pons filter to flag any that come back as WATCH or higher risk?”
Recent scan stub overview
“Can you pull the most recent token scan stub from the Pons filter without specifying a token address — I just want to see what the last flagged entry looks like?”
Technical details
Endpoint
GEThttps://desk-x402.desk-x402-gh.workers.dev/pons/filterWhen to prefer
Use this endpoint when you need a fast, on-demand risk verdict for a specific token address on the Base blockchain and are willing to pay $1 USDC per call via x402 micropayment. Prefer it over manual on-chain analysis when you need a structured WATCH/SAFE/DANGER classification without building your own heuristics. It is especially suited for agent workflows that gate trading or interaction decisions on a token risk score.
Side effects
- Missing or invalid token address returns a stub/fallback mode rather than an error
- Payment not provided or invalid x402 payment header results in 402 Payment Required
- Unsupported network (non-Base eip155:8453 for v2) may cause payment rejection
- Malformed query parameters return a 400-level error
- Token not indexed or unknown may return a generic or inconclusive verdict
