# Token Assessment Evidence Coverage — Named Scenario Comparison

> Token Assessment Evidence Coverage — Named Scenario Comparison 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).

Compares named alternative scenarios against a baseline for token assessment evidence coverage, calculating how many observed fields cover requested fields across up to 20 labeled scenarios.

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-named-scenario-comparison-00f96af1 -d '<json body>'
```

Example prompt: Run a named scenario comparison for token evidence coverage: my baseline has 8 observed fields out of 10 requested, and I want to compare it against one alternative scenario called 'High Coverage' with 9.5 observed fields.

## When to prefer this

Use this endpoint when you need a deterministic, multi-scenario comparison of token evidence coverage ratios using only your supplied field observation counts — no external data, live scans, or trading signals involved. Prefer it over single-point coverage checks when you have 2–20 named alternative scenarios to evaluate simultaneously against a common baseline.

## Known failure modes

- Missing or invalid baseline observed_fields/requested_fields causes validation error
- Scenarios array empty or exceeds 20 items returns schema violation
- requested_fields must be greater than 0 (exclusiveMinimum enforced)
- Scenario label exceeds 80 characters or is empty returns validation error
- Scenario overrides object must have at least one property or request is rejected
- Non-numeric field values cause type validation failure

## How this service works

Token assessment evidence coverage — Named scenario comparison: Named scenario comparison 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 named scenario comparison report.

## Output

A bounded named scenario comparison report showing evidence coverage calculations for each labeled scenario relative to the baseline (observed_fields vs requested_fields ratios), with deterministic verdicts based on supplied field counts. No live scan or external data is fetched.
