Quantum Calibrations - Condition Coverage Map

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.

• 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
