# Quantum Calibrations - Condition Coverage Map

> Quantum Calibrations - Condition Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035138/call, status unknown (last checked 2026-10-29).

Validates that every requested metric and ordered-qubit target has exactly one explicitly measured declaration in a supplied quantum calibration record.

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 quantum-calibrations-condition-coverage-map-acbf1e48 -d '<json body>'
```

Example prompt: Check the condition coverage map for quantum calibration run 'qrun-20240315-alpha', revision 'v2', using the 'synthetic' data class — verify that all required qubit targets ['q0','q1','q3','q7'] are each covered by exactly one measurement declaration from the supplied measurements list.

## When to prefer this

Choose this endpoint when you need to confirm that a quantum calibration dataset provides exactly one explicit measurement declaration per required qubit target or metric — specifically for coverage completeness validation against a supplied record, not for independent certification or general quantum simulation. Prefer over generic data validation tools when working with quantum backend calibration runs identified by runRef and revision.

## Known failure modes

- Missing runRef or revision causes validation rejection
- measurements or requiredTargets arrays empty or exceed 32-item limit
- dataClass value outside allowed enum returns schema error
- nonpersonalMetadata not set to true blocks processing
- Mismatch between supplied measurements and requiredTargets results in uncovered target errors
- Invalid backendRef returns backend not found error
- Payment failure via x402 protocol prevents call execution

## How this service works

Require one explicitly measured declaration for every requested metric/ordered-qubit target in an exact Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a condition coverage map indicating whether each requested metric or ordered-qubit target has exactly one explicitly measured declaration in the supplied record, highlighting any gaps, missing declarations, or duplicate coverage conflicts.
