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 an ordered array of IP addresses extracted from the header, the total hop count, a trust_decision field (currently 'not_evaluated'), evidence metadata (including whether data was retained, a SHA-256 hash of the input, and external call count), and a status field indicating success.
Example use cases
Identify originating client IP
“I have this X-Forwarded-For header from an incoming request — '203.0.113.1, 198.51.100.7' — can you break it down into the individual IPs and tell me the hop count?”
Audit proxy chain for web reliability
“We're seeing suspicious traffic and I want to inspect the proxy chain. Can you parse this X-Forwarded-For header string '10.0.0.1, 192.168.1.5, 203.0.113.44' and tell me how many hops are involved?”
Validate forwarded header format
“Before trusting this X-Forwarded-For header in our API gateway, can you extract all the IP addresses from '198.51.100.7, 203.0.113.1' and confirm the hop count?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x-forwarded-for-chain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call, no-signup utility to parse X-Forwarded-For headers into structured IP lists with hop counts — especially in agent workflows that require verifiable, in-memory-only processing with cryptographic input hashing for auditability. Prefer it over writing custom parsing logic when you need a reliable, standardized result with evidence metadata.
Side effects
- Malformed or empty header string may yield an empty address array or parsing error
- Header exceeding 8192 characters will be rejected
- Network or payment failure may prevent the call from completing
- Invalid JSON input returns a 4xx error
