# Token Circulating-to-Diluted Value — Adjacent Period Changes

> Token Circulating-to-Diluted 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 2026-10-16).

Calculates period-over-period changes in the ratio of a token's market cap (circulating value) to its fully diluted valuation (FDV) across a supplied time series of observations.

## 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-circulating-to-diluted-value-adjacent-period-changes-c00fa081 -d '<json body>'
```

Example prompt: Here are four consecutive daily snapshots for a token — market caps of $2M, $2.2M, $2M, $2.2M and FDVs of $4M, $4.4M, $4M, $4.4M — can you calculate the adjacent period changes in the circulating-to-diluted value ratio across those observations?

## When to prefer this

Choose this endpoint when you have a time-ordered series of market cap and fully diluted valuation snapshots for a token and need to quantify how the circulating-to-diluted ratio changes between consecutive periods. It is purpose-built for tokenomics time-series analysis and returns a deterministic, bounded result — ideal when you want a repeatable calculation rather than a live market lookup or subjective score.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observations required for adjacent period comparison
- fdv_usd or market_cap_usd is zero or negative — values must be strictly greater than zero
- More than 200 rows supplied — exceeds maxItems limit
- Missing required fields market_cap_usd or fdv_usd in any row
- Payment of 0.01 USDC not provided — x402 payment required per call

## How this service works

Token circulating-to-diluted value — Adjacent period changes: Adjacent period changes for Token circulating-to-diluted value. 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 adjacent (period-over-period) changes in the circulating-to-diluted value ratio derived from the supplied market_cap_usd and fdv_usd time-series rows. Each output element reflects the difference or change in the ratio between consecutive input observations. Result is deterministic given the same input; not a live scan or trade recommendation.
