# Token Unlock Notional Value — Adjacent Period Changes

> Token Unlock Notional Value — Adjacent Period Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes period-over-period changes in token unlock notional value (tokens × spot price) across a supplied sequence of unlock observations.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-unlock-notional-value-adjacent-period-changes-b702a1ae -d '<json body>'
```

Example prompt: Calculate the adjacent period changes in token unlock notional value for these four observations: 100,000 tokens at $2.00, then 110,000 tokens at $2.20, then 100,000 tokens at $2.00, then 110,000 tokens at $2.20.

## When to prefer this

Use this endpoint when you need a deterministic, caller-supplied calculation of how token unlock notional value changes between adjacent periods at a given spot price, without requiring live market feeds. Ideal for tokenomics analysis, vesting schedule review, or period-over-period unlock value reporting where you supply all observation data yourself.

## Known failure modes

- Fewer than 2 rows provided — minimum input requirement not met
- Row missing required fields (unlock_tokens or price_usd) — validation error
- price_usd or unlock_tokens set to zero or negative — violates exclusiveMinimum constraint
- More than 200 rows supplied — exceeds maxItems limit
- Non-numeric values in numeric fields — schema validation failure
- Payment not included or insufficient — x402 payment required error

## How this service works

Token unlock at supplied spot price — Adjacent period changes: Adjacent period changes for Token unlock at supplied spot price. 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 report of adjacent period changes in token unlock notional value (tokens × price_usd) for each consecutive pair of input observations, computed deterministically from the supplied rows without any live market data or trade recommendations.
