# Token Rule-Flag Fraction Local Finite-Change Elasticity

> Token Rule-Flag Fraction 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 2026-10-10).

Computes the local finite-change elasticity of a token's rule-flag fraction (flagged_rules / evaluated_rules) given a baseline 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-rule-flag-fraction-local-finite-change-elasticity-d02ffc19 -d '<json body>'
```

Example prompt: Can you calculate the local finite-change elasticity of the flagged_rules fraction for a token with a baseline of 3 flagged rules out of 15 evaluated rules, using a 1% step size?

## When to prefer this

Use this endpoint when you need a deterministic, point-in-time local elasticity measure for a token's rule-flag fraction and already have baseline rule counts. Prefer this over general analytics APIs when you specifically need finite-difference sensitivity around a caller-supplied baseline for compliance rule ratios, and when you want a fixed-cost ($0.01 USDC) bounded report rather than a live scan or model-based recommendation.

## Known failure modes

- evaluated_rules set to zero or missing exclusiveMinimum violation causing division error
- step_percent outside allowed range 0.01–10 returns validation error
- baseline values exceeding maximum bounds (1e16) rejected
- invalid field enum value (not flagged_rules or evaluated_rules) returns error
- malformed JSON body returns 400-level error

## How this service works

Token supplied rule-flag fraction — Local finite-change elasticity: Local finite-change elasticity for Token supplied rule-flag fraction. 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 token rule-flag fraction field, quantifying how much the ratio (flagged_rules / evaluated_rules) changes in response to a small percentage step from the provided baseline. Output is a deterministic numerical elasticity value with supporting calculation context, not a live scan or trade recommendation.
