# Token Assessment Evidence Coverage — Distribution Summary

> Token Assessment Evidence Coverage — Distribution Summary 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 a distribution summary report showing how completely a set of token observations covers requested evidence fields, using a deterministic calculation against caller-supplied data.

## 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-assessment-evidence-coverage-distribution-summary-b7b6762a -d '<json body>'
```

Example prompt: Can you run a distribution summary on my token evidence coverage? I have 4 rows — first two rows each observed 8 out of 10 requested fields, and the last two observed 8.8 out of 11 requested fields.

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC), deterministic distribution summary of token evidence field coverage across multiple observation rows — particularly when you already have structured observed vs. requested field counts and want a statistical summary rather than a live data scan or trade recommendation.

## Known failure modes

- Fewer than 2 rows supplied — minItems violation causes request rejection
- requested_fields set to 0 or negative — exclusiveMinimum constraint violation
- More than 200 rows submitted — maxItems exceeded
- Non-numeric values for observed_fields or requested_fields — schema type mismatch
- observed_fields or requested_fields exceed maximum allowed value (10^16)

## How this service works

Token assessment evidence coverage — Distribution summary: Distribution summary for Token assessment evidence coverage. 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 distribution summary report.

## Output

A bounded distribution summary report describing how observed token evidence fields are distributed relative to requested fields across the supplied rows, computed deterministically from the caller's input — not a live scan or safety verdict. Includes aggregated coverage statistics per the 50-profile engine preset.
