# Token Assessment Evidence Coverage — Target Gap Calculator

> Token Assessment Evidence Coverage — Target Gap Calculator 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).

Calculates the gap between observed and requested evidence fields for a token assessment, comparing actual coverage against a numeric target threshold.

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-assessment-evidence-coverage-target-gap-calculator-93ee6325 -d '<json body>'
```

Example prompt: Calculate the evidence coverage gap for my token assessment — I observed 8 fields out of 10 requested, and my target coverage score is 100.

## When to prefer this

Use this endpoint when you need a fast, deterministic calculation of how much evidence coverage is missing for a token assessment relative to a numeric target — particularly when you already have counts of observed vs. requested evidence fields and want a gap report without triggering a live scan or receiving investment advice.

## Known failure modes

- requested_fields must be greater than 0 (exclusiveMinimum enforced); passing 0 causes validation error
- observed_fields exceeding requested_fields may produce negative or zero gap
- target value out of allowed range (±1e18) returns validation error
- missing required values object or its required properties causes request rejection

## How this service works

Token assessment evidence coverage — Target gap calculation: Target gap calculation 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 target gap calculation report.

## Output

Returns a deterministic target gap calculation report showing the numerical or threshold-based gap between current evidence coverage (observed vs. requested fields) and the specified target value, without performing a live scan or making trade recommendations.
