## How to call it through Zero

```sh
zero fetch --capability agenttoll-base-radar-history-snapshot-ab373062
```

Example prompt: Can you pull the AgentToll radar history snapshot for Base from August 10th, 2026 — I want to see which new token pools were detected that day?

## When to prefer this

Use this endpoint when you need a historical, immutable record of the Base new token radar for a specific past date — particularly when auditability or reproducibility matters (e.g. backtesting, auditing, compliance). Prefer over live radar endpoints when you need a point-in-time snapshot rather than current data. The git-pinned revision makes this suitable for verifiable historical analysis.

## Known failure modes

- Date before history start (2026-08-06) returns no data or error
- Invalid date format returns a validation error
- Date in the future returns no snapshot (not yet captured)
- Network or payment failure results in 402 or connection error
- Malformed query parameter pattern causes rejection

## How this service works

Published radar snapshot pinned to an immutable git revision. The payment receipt proves payment, not snapshot content or capture time. ?date=YYYY-MM-DD, default latest

## Output

An immutable radar snapshot object representing new Base token pool data for the requested date, pinned to a specific git revision for auditability. The snapshot contains pool listings detected on that day, with the content fixed at the git revision at time of capture. Payment receipt proves payment only, not snapshot content or capture time.
