# Token Liquidity Relative Change — Adjacent Period Changes

> Token Liquidity Relative Change — 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 2026-10-16).

Calculates the relative percentage change in token liquidity between two adjacent time periods for one or more token 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-liquidity-relative-change-adjacent-period-changes-75a0675b -d '<json body>'
```

Example prompt: Can you calculate the relative liquidity change between adjacent periods for these token observations — current liquidity 120,000 and previous liquidity 100,000, and also current 132,000 vs previous 110,000?

## When to prefer this

Choose this endpoint when you need a fast, deterministic computation of relative liquidity change between two adjacent time periods for one or more token observations, and you don't need a live blockchain scan or predictive model. It is ideal for batch processing up to 200 token pairs at $0.01 per call when you already have current and previous liquidity figures and want a consistent, repeatable calculation.

## Known failure modes

- Missing required fields (current_liquidity or previous_liquidity) returns a validation error
- Values of zero or below for either liquidity field are rejected (exclusiveMinimum: 0)
- Submitting fewer than 2 rows or more than 200 rows triggers a schema validation error
- Payment failure or insufficient USDC balance prevents the call from completing
- Extremely large liquidity values approaching the maximum (10^16) may cause precision edge cases

## How this service works

Token liquidity relative change — Adjacent period changes: Adjacent period changes for Token liquidity relative change. 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 containing the relative (percentage) change in liquidity between the current and previous period for each supplied token observation row. The result is deterministically calculated — not a live scan or trade recommendation — and covers all rows submitted (up to 200).
