How has this x402 endpoint's price changed?

See how an x402 endpoint's price, payout address, availability and latency have changed over time, with every terms change dated and recorded.

We look this endpoint up in what we have already observed. Nothing is fetched from the endpoint — History never probes.

Exact record

Every entry below is a change we observed, written once to an append-only log and never edited. The dates are the moment we observed the change. This is the record an operator would be shown.

Sampled telemetry

These figures are estimates. They come from a sampled dataset: each stored measurement stands for several real ones, and old measurements age out. They are good enough to describe a trend and are not evidence about any particular request.

Changes

No changes in this window. Nothing we track about this endpoint's terms moved. That is a finding, not a gap — the log records changes, so an empty log means the terms held.

Written to an append-only log that a database trigger will not let anyone update or delete. A mistake is corrected by appending a correction, so nothing here can be quietly rewritten.

No samples in this window

We asked, and there are no probe samples for this endpoint in this window. The exact record above is unaffected.

We asked, and there are no probe samples for this endpoint in the last 30d.

Just probed. We probed this endpoint in the last few minutes, and the sampled figures may not include that probe yet.

Aggregated from a sampled dataset by total sample weight, not by counting stored rows. Retention is bounded, so an old window thins out. These figures describe a trend; they are not a record of any particular request.
