# Token Assessment Evidence Coverage — Two-Input Scenario Grid

> Token Assessment Evidence Coverage — Two-Input Scenario Grid 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).

Generates a deterministic two-input scenario grid report evaluating evidence coverage for token assessment based on supplied observed and requested field counts.

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-two-input-scenario-grid-f66cd598 -d '<json body>'
```

Example prompt: Run a two-input evidence coverage scenario grid for token assessment using observed_fields on the X axis with values [6, 8, 10] and requested_fields on the Y axis with values [8, 10, 12], with a baseline of 8 observed fields and 10 requested fields.

## When to prefer this

Use this endpoint when you need a deterministic, low-cost ($0.01 USDC) two-dimensional scenario analysis of token evidence coverage across combinations of observed and requested field counts. It is purpose-built for coverage stress-testing across a grid rather than a single-point calculation. Prefer it over single-input or single-point assessments when you need to understand how coverage verdicts shift across a range of field count scenarios simultaneously.

## Known failure modes

- values_x or values_y arrays exceed 10 items — request rejected
- requested_fields baseline set to 0 or negative — violates exclusiveMinimum constraint
- field_x and field_y set to the same enum value — may produce degenerate or uninformative grid
- extreme field count values near the maximum (1e16) may produce unexpected numeric results
- payment not processed — endpoint returns 402 and no report is generated

## How this service works

Token assessment evidence coverage — Two-input scenario grid: Two-input scenario grid 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 two-input scenario grid report.

## Output

A bounded two-input scenario grid report containing deterministic coverage verdicts or caller-threshold outcomes for each combination of the specified X and Y axis field count values, relative to the supplied baseline. The report covers all pairwise combinations of values_x and values_y entries.
