## 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 tradeos-tech-82eae557 -d '<json body>'
```

Example prompt: Pull the last 24 hours of TradeOS fusion signal history for ETH — I want up to 200 rows showing scores, decision states, and timestamps so I can audit what changed and backfill my dashboard.

## When to prefer this

Choose this endpoint when you need a short, recent audit window (today's history) rather than multi-day research — ideal for dashboard backfills, intraday behavior checks, or quick context snapshots without the cost of the 7-day history endpoint. Use over the real-time snapshot when you need to replay or audit what changed, not just the current state.

## Known failure modes

- No signals found for the specified filters in the 24h window — returns empty rows array
- Invalid filter parameters cause a 400 validation error
- Payment not received or insufficient USDC causes 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Token symbol not recognized returns empty or error response

## How this service works

A one-day signal history window for dashboard backfills, recent behavior audits, and agents that need context beyond the latest snapshot. It returns up to 200 sanitized historical rows with filters, timestamps, scores, decision states, and freshness metadata, so consumers can replay what changed without buying or reselling a raw feed. Read-only history, not execution.

## Output

A JSON array of up to 200 sanitized historical signal rows covering the past 24 hours, each containing signal scores, decision states, filter metadata, timestamps, and freshness indicators — no raw feed, no execution data, read-only research output.
