Trace URL redirect chains via an x402-payable endpoint.
What it does
This endpoint at netintel-production-440c.up.railway.app/redirect/trace appears to provide URL redirect-chain tracing as a paid x402 service. The endpoint is live and returns an HTTP 402 challenge when accessed via GET, indicating it is configured for per-request payment via the x402 protocol.
Very little documentation is available. The provider's origin server returns 404 on all standard documentation paths (/docs, /api, /pricing, /README), and the 402 challenge body is empty, so pricing details (token, amount, network) could not be determined from the probe. The endpoint name "redirect/trace" strongly suggests it follows HTTP redirects for a given URL and returns the full chain of intermediate hops, status codes, and final destination — a common network-intelligence operation used in security analysis, link auditing, and ad-tech verification.
Because no OpenAPI schema, examples, or pricing information were captured, consumers should treat this listing as a stub. The endpoint is reachable and responds correctly with 402, but all functional details are inferred from the URL path alone.
Capabilities
Use cases
- —Tracing the full redirect chain of a shortened or obfuscated URL to reveal the final destination
- —Auditing advertising click-through URLs for compliance and fraud detection
- —Security analysis of suspicious links to identify malicious redirect hops
Fit
Best for
- —Security researchers analyzing suspicious URLs
- —Ad-tech teams verifying click-through redirect chains
- —Developers building link-auditing or URL-inspection tools
Not for
- —General-purpose web scraping or content extraction
- —Bulk domain reputation scoring (no evidence of batch support)
Quick start
curl -i https://netintel-production-440c.up.railway.app/redirect/trace?url=https://example.comEndpoint
Quality
The endpoint is live (returns 402) but the challenge body is empty, there is no documentation, no OpenAPI schema, no pricing info, and no examples. All capabilities are inferred solely from the URL path. This is effectively a stub listing.
Warnings
- —Empty 402 challenge body — pricing (token, amount, network) is unknown
- —No documentation found at any standard path (/docs, /api, /pricing, /README)
- —No OpenAPI or schema available; request/response formats are unknown
- —All functional claims are inferred from the URL path '/redirect/trace' only
