# Token Fully Diluted Value — Sequential Input-Change Attribution (Waterfall)

> Token Fully Diluted Value — Sequential Input-Change Attribution (Waterfall) is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes a sequential (waterfall) attribution of how changes in token price and total supply each contribute to a change in a token's fully diluted value (FDV).

## 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-fully-diluted-value-sequential-input-change-attribution-waterfall-c022288d -d '<json body>'
```

Example prompt: My token was priced at $2.00 with 2,000,000 fully diluted tokens before, and now it's $2.20 with 2,200,000 tokens — can you run a waterfall attribution to show how much of the FDV change came from the price increase vs the supply increase?

## When to prefer this

Use this endpoint when you have two snapshots of a token's price and fully diluted supply and need to decompose the FDV change into its constituent drivers in a sequential (waterfall) format. Prefer this over a simple FDV delta calculation when you need to separate the price effect from the supply/dilution effect for investor reporting, post-event analysis, or financial model attribution. This is not a live market scanner or a trade signal — it is a deterministic, offline computation on caller-supplied data.

## Known failure modes

- Missing required fields (price_usd or fully_diluted_tokens in before or after) returns a validation error
- Zero or negative values for price or token count are rejected (exclusiveMinimum: 0)
- Extremely large values near the schema maximum may produce precision edge cases
- Payment failure (insufficient USDC balance) blocks the call before computation
- No live market data is fetched — results are only as current as the caller's supplied observations

## How this service works

Token fully diluted value — Sequential input-change attribution: Sequential input-change attribution for Token fully 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 sequential input-change attribution report.

## Output

A deterministic sequential (waterfall) attribution report showing the before and after fully diluted values, the step-by-step contribution of each input change (price_usd and fully_diluted_tokens) to the total FDV delta, and the residual or interaction term if any — allowing the caller to understand exactly how much of the FDV movement is explained by price changes versus token supply changes.
