How this service works
Real-time server-side B2B buying-intent signal extraction and 3-touch hyper-personalized outbound sequence engine backed by PostgreSQL, Node 22 Serverless, TON Connect 2.0, and x402 API.
Output
Returns an audit report for the submitted URL or domain indicating x402 protocol compliance status, detected payment headers, API endpoint metadata, and any relevant signals about the site's payment integration readiness.
Example use cases
Check competitor API for x402 support
“Can you audit api.acme.com and tell me if it has x402 payment protocol support enabled, and what endpoints are exposed?”
Validate own domain before launch
“Before we go live, can you run an x402 audit on our staging domain https://staging.myproduct.com to confirm our payment headers and API compliance look correct?”
Research x402 ecosystem vendors
“I'm building a list of B2B tools that support x402 payments — can you audit https://somevendor.io and tell me what x402 signals you find?”
Technical details
Endpoint
GEThttps://nexussdr-ai.run402.com/api/x402-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a specific URL or domain has implemented the x402 payment protocol, especially when building tooling to map the x402 ecosystem, validate your own integration, or research competitors' payment infrastructure. It is not suited for full web crawls, content scraping, or non-x402 compliance checks.
Side effects
- Invalid or non-HTTPS URL returns an error
- Target domain unreachable or times out
- No x402 signals detected on an otherwise valid domain
- Malformed input schema causes 400 error
- Payment of $0.01 USDC required per call; missing payment returns 402
