How this service works
Agent decision products for procurement, vendor risk, API QA and public-web buy-or-skip workflows. Strict x402 payment is required before fulfillment.
Output
Returns a JSON object with a url_health verdict (BUY or skip), reason_codes explaining the decision, a recommended_action (e.g. 'proceed'), and a site_summary with a PASS/FAIL verdict, plus a machine_verifiable boolean confirming the result can be used programmatically.
Example use cases
Vendor site risk check before onboarding
“Before I onboard this new supplier, can you run a health and risk check on https://supplierco.io and tell me if I should proceed or skip them?”
API endpoint QA before integration
“I'm about to integrate with https://payments-api.thirdparty.com — can you check its URL health and let me know if it passes QA or if there are any red flags?”
Public web buy-or-skip for e-commerce
“I'm considering buying from https://new-shop.example.com — can you assess the site's health and give me a machine-verifiable verdict on whether I should go ahead or skip it?”
Technical details
Endpoint
POSThttps://ohd-machine-x402-v2.hibiki3027.workers.dev/api/url-health?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a structured, machine-verifiable buy-or-skip or pass/fail verdict on a URL before executing a procurement, vendor onboarding, or API integration workflow. It is particularly suited for automated pipelines that require a codified reason-code explanation and a recommended action, rather than a raw uptime ping or generic link-checker. Prefer it over simple uptime monitors when vendor risk context and agent-readable decision logic are required.
Side effects
- Payment not provided or invalid x402 payment header — request rejected before fulfillment
- URL input exceeds maxItems of 3 — validation error returned
- Invalid URI format in urls array or site_url — schema validation failure
- Unreachable or non-existent URL submitted — may return SKIP/FAIL verdict rather than an error
- Objective string exceeds 500 characters — rejected with input validation error
