How this service works
Procedure that classifies whether an x402-protected endpoint is actually payable from a browser-agent context versus an API-agent context. Covers Cloudflare Kitesurf agent browser, SignalMint browser-based agents, Q+Pay browser paywalls, user gesture requirements, wallet connectivity, CORS, redirects, challenge types, payment request format, and fallback behavior.
Output
Returns a structured JSON response containing an eligibility verdict (ok/paid booleans), a prose decision procedure brief explaining whether the x402 endpoint is payable from browser-agent vs API-agent context, plus metadata including the service slug, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and payment transaction details if applicable.
Example use cases
Browser agent x402 paywall compatibility check
“I'm building a browser-based agent using SignalMint and it needs to access an x402-protected API — can you classify whether that endpoint is actually payable from a browser context or only from a server-side API agent, and flag any CORS or wallet issues?”
Cloudflare Kitesurf agent payment eligibility
“My Cloudflare Kitesurf browser agent hit an x402 paywall and I'm not sure if it can complete the payment — can you run the eligibility classification to tell me if the challenge type and payment request format are compatible with browser-agent flows?”
Q+Pay browser paywall fallback planning
“I'm integrating with a Q+Pay browser paywall via x402 and need to know upfront whether my browser agent can pay it directly or if I need a fallback to an API-agent context — can you classify the eligibility and explain what happens if the browser payment fails?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/browser-agent-x402-eligibility-classification-pr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to determine upfront whether an x402-protected resource can be paid by a browser-based agent (e.g. Cloudflare Kitesurf, SignalMint) versus requiring a server-side API agent — especially when CORS policies, user gesture requirements, wallet connectivity, or redirect/challenge types are potential blockers. Prefer this over generic x402 documentation when you need an actionable, agent-readable decision procedure with explicit fallback guidance.
Side effects
- Missing required 'type' or 'method' fields returns a validation error
- Unsupported HTTP method (POST, PUT, PATCH) rejected by enum constraint
- Invalid 'meta' query param value (not '0' or '1') causes schema rejection
- Network or provider failure returns non-200 with no classification result
- Topic override not recognized may produce generic rather than tailored classification
