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 reported-locked-token-supply-adjacent-period-changes-bdf8316e -d '<json body>'
```

Example prompt: I have four periods of token data — period 1: 600,000 locked out of 2,000,000 total; period 2: 660,000 locked out of 2,200,000 total; period 3: 600,000 locked out of 2,000,000 total; period 4: 660,000 locked out of 2,200,000 total — can you calculate the adjacent period changes in locked token supply across those observations?

## When to prefer this

Choose this endpoint when you have a time-ordered sequence of locked token supply observations (2–200 rows) and need a deterministic, cost-efficient ($0.01 USDC) report of how locked supply changed between each adjacent period. It is purpose-built for tokenomics analytics, vesting schedule review, and unlock event detection. Prefer it over general-purpose analytics tools when you specifically need period-over-period locked supply deltas from raw locked_tokens and total_tokens pairs.

## Known failure modes

- Fewer than 2 rows submitted — minimum of 2 rows required
- locked_tokens or total_tokens missing from a row — required fields
- total_tokens set to 0 — exclusiveMinimum constraint violated
- Array exceeds 200 rows — maxItems limit
- Values exceed 10^16 — maximum constraint violated
- Malformed numeric inputs causing schema validation failure

## How this service works

Reported locked token supply — Adjacent period changes: Adjacent period changes for Reported locked token supply. 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

Returns a bounded adjacent period changes report showing the differences in locked token supply between each consecutive pair of observation rows, based on deterministic calculation. The report covers only the submitted token observations and is not a live scan or trade recommendation.
