How this service works
Purchase: Public HTTP Redirect Chain — Status, Origin & Downgrade Evidence
Output
Returns a job_id, initial status string, and thread_id that the agent can use to poll for the completed redirect chain analysis — including each redirect hop's status code, origin server, and any protocol downgrade evidence detected.
Example use cases
Example prompt
“Can you trace the full redirect chain for https://example.com and check whether there are any HTTP-to-HTTPS downgrades or suspicious origin hops along the way?”
Technical details
Endpoint
POSThttps://api.the402.ai/v1/services/svc_eec401d863b44d6f/purchaseWhen to prefer
Use this endpoint when you need to programmatically audit the full HTTP redirect chain for a public URL — especially when investigating protocol downgrades (HTTPS to HTTP), identifying the true origin server behind redirects, or gathering evidence of security misconfigurations in redirect paths. Prefer this over manual browser inspection when you need structured, machine-readable redirect chain data.
Side effects
- Payment failure or insufficient USDC balance returns an authorization error
- Invalid or unreachable URL causes job to fail with error status
- Rate limiting if too many requests are submitted in quick succession
- Job may remain in pending status if the target URL is extremely slow to respond
- Service ID mismatch returns 404 or invalid service error
