# Token Supply Relative Change — Local Finite-Change Elasticity

> Token Supply Relative Change — 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 2026-10-11).

Computes the local finite-change elasticity of token supply relative change given a baseline old/new supply and a step percentage.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-supply-relative-change-local-finite-change-elasticity-ca45c009 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of token supply relative change for a baseline where old supply is 1000 and new supply is 1100, using a step percent of 1, with the field set to new_supply.

## When to prefer this

Use this endpoint when you need a fast, deterministic, single-call elasticity calculation for a token supply relative change scenario with known baseline values and do not require live market data, Monte Carlo simulation, or multi-asset analysis. Prefer this over general-purpose math APIs when you specifically need a tokenomics-scoped, bounded local finite-change elasticity report with a configurable step size.

## Known failure modes

- new_supply or old_supply set to 0 or negative — violates exclusiveMinimum constraint, returns validation error
- step_percent outside 0.01–10 range — rejected by schema validation
- Missing required baseline fields — returns 400 bad request
- Values exceeding maximum (1e16) — schema rejection
- Network or payment failure — 402 or 5xx returned if x402 payment is not correctly processed

## How this service works

Token supply relative change — Local finite-change elasticity: Local finite-change elasticity for Token supply relative change. 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

A deterministic bounded local finite-change elasticity report quantifying how much the token supply relative change responds to a marginal perturbation of the specified field (new_supply or old_supply) at the given baseline, expressed as an elasticity coefficient. No live market data, safety guarantees, or trade recommendations are included.
