## 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 token-bid-ask-spread-ordered-trend-analysis-3e62673b -d '<json body>'
```

Example prompt: Analyze the ordered trend in these token bid-ask spread observations: [{bid:0.98, ask:1.02},{bid:1.078, ask:1.122},{bid:0.98, ask:1.02},{bid:1.078, ask:1.122}] — is the spread trending up, down, or sideways?

## When to prefer this

Choose this endpoint when you have a time-ordered sequence of token bid and ask price pairs and need a deterministic, bounded trend analysis of how the spread is evolving. Ideal for pre-trade liquidity checks, post-trade spread recovery analysis, or feeding spread trend signals into automated trading logic. Not for live market scanning or real-time data feeds — caller must supply the observation rows.

## Known failure modes

- Fewer than 2 rows submitted — minimum minItems:2 required
- Bid or ask values are zero or negative — exclusiveMinimum:0 enforced
- More than 200 rows submitted — maxItems:200 limit exceeded
- Non-numeric bid or ask values cause schema validation failure
- Missing bid or ask field in any row — both are required per row schema

## How this service works

Token bid-ask spread — Ordered trend analysis: Ordered trend analysis for Token bid-ask spread. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded ordered trend analysis report.

## Output

A deterministic ordered trend analysis report for the supplied token bid-ask spread observations, including a trend direction verdict (e.g. upward, downward, flat) and supporting calculated metrics. The report reflects only the submitted rows and does not incorporate live market data or external signals.
