# Token Annualised Simple Issuance Rate — Local Finite-Change Elasticity

> Token Annualised Simple Issuance Rate — 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 annualised simple issuance rate with respect to a specified input field, given baseline token observations and a step size.

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-annualised-simple-issuance-rate-local-finite-change-elasticity-99b97aa4 -d '<json body>'
```

Example prompt: Calculate the local finite-change elasticity of the annualised token issuance rate with respect to issued_tokens, using a baseline of 1000 issued tokens, 1,000,000 starting tokens, and a 30-day period — apply a 1% step size.

## When to prefer this

Choose this endpoint when you need a deterministic, local sensitivity metric (elasticity) for a token's annualised simple issuance rate with respect to a specific input variable, given a known baseline. It is ideal for tokenomics analysis, protocol design stress-testing, or economic modelling where you want to quantify marginal rate sensitivity without running a live market scan or building a custom model.

## Known failure modes

- Invalid field value not in enum ['issued_tokens','starting_tokens','period_days'] returns validation error
- starting_tokens or period_days set to zero (exclusiveMinimum violated) returns schema error
- step_percent outside [0.01, 10] range returns validation error
- Missing required baseline fields returns 400 bad request
- Extremely large token values near maximum boundary may produce numeric precision artefacts

## How this service works

Token annualised simple issuance rate — Local finite-change elasticity: Local finite-change elasticity for Token annualised simple issuance rate. 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 bounded local finite-change elasticity report for the token annualised simple issuance rate, indicating how much the output metric changes (proportionally) in response to a small percentage perturbation in the specified input field, computed deterministically from the supplied baseline values.
