How this service works
Day-over-day x402 rail movement from on-chain settlement: total $ and tx deltas, lanes UP and DOWN (commerce, inference, dev…). Pairs with ylk-spikes for intra-day vs day-over-day reads.
Output
A JSON object containing day-over-day deltas: total dollar change, transaction count change, and per-lane (commerce, inference, dev, etc.) UP/DOWN movement indicators reflecting net shifts in on-chain x402 settlement activity compared to the prior day.
Example use cases
Example prompt
“Can you pull the day-over-day x402 rail shift report — I want to see how total dollar volume and transaction count changed since yesterday, and which lanes like commerce or inference are trending up or down?”
Technical details
Endpoint
GEThttps://ylk.one/v1/shift?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a day-over-day summary of x402 rail activity — specifically the net change in volume and transactions since yesterday, and which lanes are expanding or contracting. Prefer this over the sibling live-snapshot endpoint (ylk-spikes or the live rail endpoint) when you want daily trend context rather than intra-day or real-time pace data.
Side effects
- No data available for prior day if the rail is too new or there was a data gap — may return null deltas or 404
- Rate limit or payment failure (402) if USDC microtransaction is not processed
- Stale data if on-chain indexing is lagging — deltas may not reflect most recent blocks
- Empty lane breakdown if no activity occurred in a specific lane during the window
