## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-radar-safety-historical-snapshot-ce548241
```

Example prompt: Pull up the Base radar and safety snapshot from 2026-08-10 — I want to see which new pools were flagged that day and the on-chain Base transaction that committed the record.

## When to prefer this

Choose this endpoint when you need a historically committed, on-chain-anchored record of which Base tokens the radar surfaced on a specific past date, along with their safety verdicts. It is the right choice for auditing, back-testing, or verifying immutable historical radar snapshots rather than querying live current data.

## Known failure modes

- Date before history start (2026-08-06) returns empty or error
- Invalid date format (not YYYY-MM-DD) returns 400 validation error
- Date in the future returns no data or error
- Network or Vercel availability issues return 5xx
- Payment of 0.002 USDC not provided returns 402

## How this service works

A past day's radar+safety snapshot, exactly as committed to the public git history the day it was taken - with the Base tx that paid for it. ?date=YYYY-MM-DD, default latest

## Output

Returns the radar and safety snapshot exactly as committed to public git history for the requested date, including new Base pools that appeared that day, their safety check results (honeypot simulation, buy/sell tax, contract verification), and the Base blockchain transaction that paid for and anchors the snapshot.
