# Quantum Calibrations - Source Coverage Map

> Quantum Calibrations - Source Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035135/call, status unknown (last checked 2026-10-16).

Binds record references to an exact owner/subject/revision/content/source frame and maps source coverage across supplied rows and sources for bounded analysis.

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-source-coverage-map-18c8f5e5 -d '<json body>'
```

Example prompt: Can you run a source coverage map on these 5 quantum calibration rows against 3 sources, using public data class, and confirm nonpersonal metadata only?

## When to prefer this

Choose this endpoint when you need to declaratively bind a batch of quantum calibration records to an exact owner/subject/revision/content/source frame and produce a coverage map, particularly for public or synthetic (non-personal) datasets up to 32 rows. It is suited for governance, auditing, and bounded analysis workflows rather than independent source certification.

## Known failure modes

- Exceeds maximum of 32 rows or 32 sources — request rejected
- dataClass not one of 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Malformed rows or sources array — schema validation failure
- Network timeout or upstream compute unavailability — 5xx error

## How this service works

Bind record references to an exact owner/subject/revision/content/source frame; hash-shaped strings are declarations, not independently verified source bytes for bounded backend/run/register/measurement-pin Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured source coverage map that declares how the supplied rows bind to the given sources under an exact owner/subject/revision/content/source frame, indicating which sources cover which records without independently certifying source bytes.
