# Spectrometry Records Source Coverage Map

> Spectrometry Records Source Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035171/call, status unknown (last checked 2026-10-16).

Maps spectrometry record references to their owner, subject, revision, content, and source frame to assess coverage and binding completeness — not independent instrument certification.

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 spectrometry-records-source-coverage-map-b9d133d5 -d '<json body>'
```

Example prompt: Check source coverage for these 10 spectrometry record rows against 5 declared source references — the data is synthetic and all metadata is non-personal — and tell me which records are missing complete owner, subject, revision, content, or source frame bindings.

## When to prefer this

Use this endpoint when you need to audit or map spectrometry records against their declared source frames at the metadata level — particularly for provenance tracking, coverage gap analysis, or pre-submission validation of public or synthetic spectral datasets. Not suitable for independent instrument calibration verification or raw spectral data certification.

## Known failure modes

- rows or sources arrays empty or exceed 32-item limit — returns validation error
- dataClass not set to 'public' or 'synthetic' — rejected with enum error
- nonpersonalMetadata not set to true — request rejected
- malformed or missing record references — coverage map may show incomplete bindings
- hash-shaped strings treated as declarations only — no independent byte-level verification performed

## 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 instrument/calibration/method-pinned spectrum Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a source coverage map showing how spectrometry record rows bind to declared owner, subject, revision, content, and source frames — identifying which records have complete bindings and which have gaps. Results are declaration-level analysis based on supplied metadata, not independent instrument or calibration certification.
