How this service works
Live sanitized x402 rail snapshot JSON: pace/min, median ticket, top receivers by $, recent settlements. Machine-readable ylk.rails.public.v1 — agents branch on topServices.
Output
A machine-readable JSON object (schema ylk.rails.public.v1) containing: current transaction pace in per-minute rate, median ticket size in USD/USDC, ranked list of top receivers by total dollar volume, and a list of recent settlement events. Structured so agents can branch logic on topServices and rail health indicators.
Example use cases
Example prompt
“Pull the latest x402 rail snapshot for me — I want to see the current pace, median ticket, and top receivers by dollar volume on Base so I can decide what to do next.”
Technical details
Endpoint
GEThttps://ylk.one/v1/x402/rails?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, sanitized, machine-readable view of x402 payment rail activity — specifically for agent decision-branching on which services are active, how busy the rail is, or what the typical transaction size looks like. Prefer this over day-over-day delta endpoints (the sibling endpoint) when you need an absolute snapshot rather than change metrics.
Side effects
- Chain ID not recognized — returns error indicating unsupported chain
- Rail data temporarily unavailable — upstream on-chain indexer lag
- Payment of $0.02 USDC not received — x402 402 response requiring payment
- Malformed query parameter — returns validation error for invalid chain value
