# Token Execution Fee Relative to Notional — Benchmark Correlation

> Token Execution Fee Relative to Notional — Benchmark Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes the correlation between token execution fee-to-notional ratios and a set of user-supplied benchmark values across up to 200 observations.

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-execution-fee-relative-to-notional-benchmark-correlation-7f55ff5f -d '<json body>'
```

Example prompt: Run a benchmark correlation report on these token trade observations — fees in USD are [2, 2.2, 2, 2.2] with notional sizes [1000, 1100, 1000, 1100] — and benchmark them against [10, 20, 30, 40] to see how the fee-to-notional ratio correlates with those benchmarks.

## When to prefer this

Choose this endpoint when you need a fast, deterministic correlation analysis between token execution fee burdens (expressed as fee relative to notional) and a set of reference benchmark values. Ideal for post-trade analytics, fee auditing pipelines, or automated monitoring workflows where you supply your own observations and benchmarks and want a bounded statistical verdict without live market scanning.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observations required
- Fewer than 2 benchmark values supplied
- notional_usd is zero or negative — exclusiveMinimum enforced
- More than 200 rows or benchmarks submitted — maxItems exceeded
- Missing required fields fee_usd or notional_usd in any row
- Non-numeric values in fee or notional fields

## How this service works

Token execution fee relative to notional — Benchmark correlation: Benchmark correlation for Token execution fee relative to 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 benchmark correlation report.

## Output

A bounded benchmark correlation report showing the statistical correlation between the fee-to-notional ratios derived from the supplied token observations and the provided benchmark values. Includes a deterministic calculation result and optionally a caller-threshold verdict. Does not include live market data, safety assessments, or trade recommendations.
