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 containing the resolved absolute URL under result.resolved_url, operation status ('pass'), and an evidence block confirming no data was retained (retained: false), zero external calls made, and the SHA-256 hash of the input for verifiability.
Example use cases
Redirect chain analysis for web crawler
“I'm crawling https://shop.example.com and got a 302 response with Location header '/checkout/start' — can you resolve that to the full absolute URL so I know where to follow next?”
Verify OAuth callback redirect URL
“My auth server returned a Location header of '/oauth/callback?code=abc123' and the base URL is https://auth.myapp.io — what's the fully resolved URL that the client should be redirected to?”
Normalize API redirect for downstream processing
“I got a Location header value of '../v2/resource/42' from a response to https://api.service.com/v1/resource/ — can you compute the absolute URL that resolves to?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/location-header-resolve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, privacy-preserving URL resolution with an audit trail (input hash, no retention guarantee) and are already operating in an x402 micropayment context. Prefer it over home-rolled URL joining when you need cryptographic proof of the input processed and confirmation that no external calls were made — useful in compliance-sensitive or agent-to-agent trust scenarios.
Side effects
- Malformed or unparseable base_url returns an error status
- Location header value that cannot be meaningfully resolved against the base URL yields an error
- Input strings exceeding 8192 characters are rejected
- Invalid URL schemes may cause resolution failure
- Payment via x402 must succeed before result is returned; failed payment yields no result
