# Token Circulating Market Cap Waterfall Attribution

> Token Circulating Market Cap Waterfall Attribution 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).

Performs sequential input-change (waterfall) attribution on token circulating market capitalization, decomposing how changes in price and circulating supply drive overall market cap change.

## 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-market-cap-waterfall-attribution-b2f18e9d -d '<json body>'
```

Example prompt: Can you do a waterfall attribution on this token's market cap change — it went from $2.00 per token with 1,000,000 circulating tokens to $2.20 per token with 1,100,000 circulating tokens, and I want to see how much of the market cap increase came from the price move versus the supply increase?

## When to prefer this

Use this endpoint when you need a deterministic, auditable breakdown of how a token's circulating market cap changed between two known states, specifically attributing the delta to price and supply changes sequentially. Prefer it over general financial APIs when you want a structured waterfall decomposition rather than just a before/after difference, and when you are supplying your own token observations rather than needing live market data.

## Known failure modes

- Missing required fields (price_usd or circulating_tokens) in before or after objects returns a validation error
- Zero or negative values for price_usd or circulating_tokens are rejected (exclusiveMinimum: 0)
- Extremely large values approaching the schema maximum may cause precision issues
- Malformed JSON body returns a 400-level error

## How this service works

Token circulating market value — Sequential input-change attribution: Sequential input-change attribution for Token circulating market 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 token circulating market capitalizations, and the step-by-step contributions of each input change (price_usd and circulating_tokens) to the total market cap delta. No live market data is fetched; the calculation uses only the supplied before/after observations.
