Overview

Expands shortened URLs by tracing the full redirect chain hop-by-hop. Each step returns status code, Location header, redirect_type (permanent / temporary / meta / js), per-hop duration, and content-type, plus the final landing URL and total trace time. Useful for unmasking shortened links before fetch, and for forensic / security analysis of suspicious redirects. Use it as a URL expander, redirect chain tracer, link unshortener, shortlink resolver, bit.ly + t.co + lnkd.in + goo.gl + tinyurl resolver, final-URL fetcher, or phishing redirect inspector.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/expand-url \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/expand-url \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
