# Token Average Reported Trade Notional — Local Finite-Change Elasticity

> Token Average Reported Trade Notional — 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 2026-10-12).

Computes the local finite-change elasticity of a token's average reported trade notional with respect to a small percentage step in volume or trade count.

## 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-average-reported-trade-notional-local-finite-change-elasticity-f54ac4f5 -d '<json body>'
```

Example prompt: Can you calculate the local finite-change elasticity of average token trade notional with respect to volume_usd, using a baseline of 100000 USD volume and 200 trades, with a 1% step?

## When to prefer this

Choose this endpoint when you need a deterministic, point-in-time local sensitivity estimate (finite-change elasticity) for a token's average reported trade notional relative to a specific baseline, rather than a live market scan or a full elasticity curve. Best suited for quantitative model calibration, liquidity analysis, or risk parameterization where a single bounded elasticity coefficient at a known baseline suffices.

## Known failure modes

- Invalid field enum value (must be 'volume_usd' or 'trades')
- Baseline values of zero or negative (exclusiveMinimum:0 enforced)
- step_percent outside allowed range (0.01–10)
- Payment failure or insufficient USDC balance for x402 protocol
- Malformed JSON body returns validation error

## How this service works

Token average reported trade notional — Local finite-change elasticity: Local finite-change elasticity for Token average reported trade notional. 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's average reported trade notional, quantifying how the metric responds to a small percentage perturbation in the chosen field (volume_usd or trades) relative to the provided baseline. Returned as a deterministic calculation, not a live market signal or trade recommendation.
