# 402 History

Window: last 30 days · generated 15 Aug 2026, 15:16 UTC

## Two kinds of number on this page

- **Exact record** (exact · append-only 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** (sampled · estimate) — 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.

Every sampled figure below is prefixed `≈`. No exact figure is.

## Exact record — exact · append-only record

> **Short record.** We first observed this endpoint today, so this window is almost entirely before our record begins.

### Price, as observed

| Observed at | Price | Network |
| --- | --- | --- |
| 15 Aug 2026, 04:00 UTC | 0.002500 USDC | eip155:8453 |

The price held at each value until the next row. No value here is interpolated.

### Changes

- **15 Aug 2026** — First observed — this is where our record of this endpoint begins.
  Observed 15 Aug 2026, 05:15 UTC, recorded by crawler, scoring in force then: v1.

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 row, never by editing one.

## Sampled telemetry — sampled · estimate

- Availability over 30d: **≈100.00%** (sampled)
- Median response: **≈133 ms** (sampled)
- Slowest 5%: **≈133 ms** (sampled)
- Probe samples in window: ≈1

### Availability by bucket (sampled)

| Bucket | Availability | Samples |
| --- | --- | --- |
| 15 Aug 2026, 00:00 UTC | ≈100.00% | ≈1 |

### Latency by bucket (sampled)

| Bucket | Median | 95th | Samples |
| --- | --- | --- | --- |
| 15 Aug 2026, 00:00 UTC | ≈133 ms | ≈133 ms | ≈1 |

Aggregated by total sample weight, not by counting stored rows: the dataset samples under load,
so counting rows would under-report exactly when an endpoint is busiest.
