# Token Net Buy-Count Balance — Local Finite-Change Elasticity

> Token Net Buy-Count Balance — 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 2026-10-14).

Computes the local finite-change elasticity of a token's net buy-count balance given baseline buy/sell counts and a percentage step size.

## 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-net-buy-count-balance-local-finite-change-elasticity-f8bb7808 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity for net buy-count balance using a baseline of 120 buys and 80 sells, with a 1% step on the buy_count field — I want to see how sensitive the net buy share is to a small change in buy volume.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, single-call elasticity calculation for token net buy-count balance microstructure analysis — specifically when you have a known baseline buy/sell count and want to quantify how sensitive the net buy share is to a finite percentage change in either buy or sell count. Prefer it over live market scans or ML-based predictions when you want a pure mathematical sensitivity metric without real-time data dependencies.

## Known failure modes

- Invalid baseline values (e.g. sell_count = 0 violates exclusiveMinimum constraint) returns validation error
- step_percent outside [0.01, 10] range rejected
- Missing required baseline fields returns schema validation error
- Network or payment authorization failure returns 402 or connection error
- Extremely large baseline values near the maximum may produce floating-point precision issues

## How this service works

Token net buy-count balance — Local finite-change elasticity: Local finite-change elasticity for Token net buy-count balance. 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 specified field (buy_count or sell_count) given the provided baseline counts and step percentage. The report quantifies how the net buy-count balance (buy share) changes proportionally in response to a finite percentage change in the chosen input field — a deterministic, one-shot calculation with no live scan or trade recommendation.
