## 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-drawdown-from-peak-adjacent-period-changes-a8349675 -d '<json body>'
```

Example prompt: Can you calculate the adjacent period changes in token drawdown from peak for these four price observations: peak prices of 2.0 and 2.2 with current prices of 1.5 and 1.65 — give me the deterministic drawdown change report?

## When to prefer this

Choose this endpoint when you have a sequence of token price observations and a known peak price and need a deterministic, period-over-period calculation of how the drawdown from that peak is changing between adjacent periods. It is purpose-built for drawdown delta analysis rather than raw drawdown magnitude, making it ideal for trend detection in drawdown recovery or deterioration. Prefer this over generic analytics services when you need a cheap ($0.01 USDC), bounded, caller-supplied-data computation with no live market scanning.

## Known failure modes

- Fewer than 2 rows provided — minimum of 2 row items required
- peak_price or current_price of 0 or negative — exclusiveMinimum constraint violation
- More than 200 rows submitted — maxItems exceeded
- Missing required fields peak_price or current_price in any row — validation error
- Payment failure or insufficient USDC balance — x402 payment required error

## How this service works

Token drawdown from supplied peak — Adjacent period changes: Adjacent period changes for Token drawdown from supplied peak. 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 adjacent period changes report.

## Output

A bounded adjacent period changes report showing how token drawdown from the supplied peak price shifts between consecutive observation pairs — deterministic calculation results, not a live scan or trade recommendation. Covers up to 200 row pairs of peak_price and current_price inputs.
