How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether all specified URL fields passed validation (passed: true/false), a list of any invalid fields (invalid_fields), an operation status string, and an evidence block including whether input was retained (always false), a SHA-256 hash of the input for verifiability, and the number of external calls made (always 0 — processed entirely in memory).
Example use cases
Validate API response URL fields
“I just got a JSON response from an external API and I need to confirm that the 'avatar_url' and 'homepage' fields are real, valid URLs before I store the record — can you check that for me?”
Pre-process user-submitted profile data
“A user submitted a profile form and the data came in as JSON. Please verify that the 'portfolio_url' and 'linkedin_url' fields actually contain valid URLs so I can flag any bad entries before saving.”
QA check on scraped JSON data
“I scraped a bunch of product records and each one has an 'image_url' and 'detail_url' field. Can you run a URL validity check on those two fields for this object and tell me which ones are broken?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-url-fields-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, verifiable, pay-per-use URL field validation check on a JSON object without any signup or subscription. It is ideal for agents that need to confirm URL integrity in structured payloads before downstream processing, and when auditability matters — the SHA-256 input hash and zero-retention guarantee make it suitable for privacy-sensitive workflows. Prefer it over general-purpose HTTP validation libraries when you want a hosted, chain-verifiable result.
Side effects
- Field names listed do not exist in the provided object — may result in them being flagged as invalid or ignored
- Malformed input JSON causes a 400-level error
- Exceeding 256 field items or 128 object properties triggers input size validation errors
- Non-string values in URL fields may be flagged as invalid URLs
- Network or payment failure via x402 protocol prevents the call from completing
