How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
A JSON object containing the SKU identifier ('denylistcheck'), a title ('Denylist Check'), the price ('$0.01'), and denylist status information for the queried URL. Unpaid requests return HTTP 402 with EIP-3009 payment extras; paid requests return the denylist result.
Example use cases
Pre-integration URL safety check
“Before I connect my app to https://partner-api.io, can you run a denylist check on that URL to make sure it isn't flagged or blocked?”
Automated domain vetting pipeline
“I have a list of URLs I want to vet — start with https://suspicious-site.net and check if it appears on the denylist so I can decide whether to allowlist it.”
Marketplace listing moderation
“A seller just submitted https://newmerchant-store.com for our marketplace — can you check that URL against the denylist to see if it's flagged before we approve their listing?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/denylistcheck?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check whether a specific public URL or origin is flagged in the x402-tools v2 multi-class denylist, particularly in workflows that already support the x402 micropayment protocol (EIP-3009). It is especially suitable for automated pre-integration vetting, marketplace moderation pipelines, and safety checks on third-party domains where a $0.01 per-call cost is acceptable. Use it over general blocklist APIs when you need denylist coverage specifically tied to the x402 ecosystem.
Side effects
- HTTP 402 returned if payment (EIP-3009 via x402 protocol) is not provided or invalid
- Missing or malformed 'url' query parameter may result in an error or empty result
- Facilitator must be OpenX402; other facilitators will not be accepted
- URL not publicly accessible may return an inconclusive result
- Network timeout or service unavailability returning 5xx
