How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
A JSON object containing three fields: 'start' (the original input URL), 'hops' (an ordered array of intermediate redirect URLs visited along the way), and 'final' (the ultimate destination URL after all redirects are resolved).
Example use cases
Unwrap suspicious shortened link
“Someone sent me this link: https://t.co/abc123xyz — can you follow all the redirects and tell me the final URL it lands on? I want to make sure it's not sending me somewhere sketchy.”
Verify affiliate link destination
“I have this affiliate link https://go.example.com/offer42 and I need to know every hop it passes through before reaching the final page — trace the full redirect chain for me.”
Audit marketing campaign URL
“Can you check where https://email.campaign.co/click?id=99 redirects to and list all the intermediate hops? I want to confirm our marketing link lands on the right product page.”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/redirects?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically resolve a URL's full redirect chain — especially for shortened links, affiliate links, or tracking URLs — and you want both the intermediate hops and the final destination. It pays per-request in USDC via x402, making it suitable for on-demand agentic use without a subscription. Prefer this over browser-based resolution when you need machine-readable structured output of the redirect path.
Side effects
- Invalid or malformed URL returns an error
- Redirect loop causes timeout or excessive hop count
- Target URL is unreachable or returns a non-redirect HTTP error
- Private or firewalled URLs may not be resolvable
- Payment failure via x402 prevents request from being processed
