How this service works
PickleCheck endpoint check: is it safe to pay this x402 endpoint? Reads its payment offer and pay-to wallet (sanctions, Circle blocklist, changed pay-to, history, buyers) before you pay. It looks, never pays; unreachable or bad input are not charged.
Output
A safety report for the specified x402 endpoint including: sanctions screening results for the pay-to wallet, Circle blocklist status, whether the pay-to address has changed, historical payment activity, and an overall risk assessment. The endpoint reads only and never executes a payment. Unreachable URLs or bad input return an error without any charge.
Example use cases
Pre-payment agent safety gate
“My autonomous agent is about to pay an x402 endpoint at https://data-service.example.com/query — can you check if that endpoint's pay-to wallet is sanctioned or on the Circle blocklist before we send any USDC?”
Detecting changed pay-to wallet
“I noticed the wallet address on https://analytics.example.com/report looks different from last week — can you run a PickleCheck on that URL to see if the payment destination has changed suspiciously?”
Screening unknown x402 API marketplace listing
“I found a new x402 endpoint being advertised on agentic.market at https://unknown-provider.io/api/data — run a safety check on it and tell me if there are any red flags in its payment history or wallet screening.”
Technical details
Endpoint
GEThttps://picklecheck.onrender.com/endpoint-check?utm_source=zero.xyzWhen to prefer
Use this endpoint before any AI agent pays an x402-priced API, especially when the endpoint is newly discovered, sourced from a marketplace, or the pay-to wallet address is unfamiliar. It is the right choice when you need pre-payment due diligence specific to the x402 protocol, including wallet sanctions screening and Circle blocklist checks, rather than generic blockchain analytics.
Side effects
- Endpoint URL is unreachable or returns non-x402 response — no charge, error returned
- Invalid or malformed URL input — validation error returned
- Pay-to wallet address cannot be resolved from payment offer
- Sanctions/blocklist API temporarily unavailable — partial results or timeout
- Rate limiting on downstream compliance data sources
