# Token Circulating Market Cap — Local Finite-Change Elasticity

> Token Circulating Market Cap — Local Finite-Change Elasticity 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).

Computes the local finite-change elasticity of a token's circulating market capitalization with respect to a specified input field (price or circulating supply), given a baseline and a small percentage step.

## 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-local-finite-change-elasticity-7303fd83 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of this token's circulating market cap, using a baseline price of $2.50 and 1,000,000 circulating tokens, varying price_usd by a 1% step.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, single-call computation of how sensitively a token's circulating market cap responds to marginal changes in price or supply — particularly for quantitative analysis, scenario modeling, or risk assessment on user-supplied token data, without needing live market data feeds or complex on-chain queries.

## Known failure modes

- Invalid or missing baseline values (price_usd or circulating_tokens ≤ 0) result in validation error
- step_percent outside allowed range (0.01–10) returns schema validation failure
- Unrecognized field enum value returns bad request
- Payment not included or invalid results in 402 Payment Required
- Server-side computation error returns 500

## How this service works

Token circulating market value — Local finite-change elasticity: Local finite-change elasticity 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 local finite-change elasticity report.

## Output

Returns a bounded local finite-change elasticity report for the token's circulating market cap: a numeric elasticity coefficient indicating how much the market cap changes (proportionally) in response to a small finite percentage change in the selected field (price or circulating supply), calculated deterministically from the supplied baseline values and step size. Not a live market scan or trade signal.
