# Spectrometry Records – Condition Coverage Map

> Spectrometry Records – Condition Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035174/call, status unknown (last checked 2026-10-25).

Validates that each requested spectrometry reference/revision has exactly one caller-declared calibration within the specified instrument/method frame and time window, returning a coverage map of satisfied vs. unsatisfied calibration requirements.

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-condition-coverage-map-751291a0 -d '<json body>'
```

Example prompt: Check calibration coverage for my spectrometry records: instrument ref 'SPEC-002', method digest 'sha256-abc123', assessment window starting 2024-01-01 and ending 2024-06-30, with public data class — I need to verify that these three required calibrations ['CAL-001','CAL-002','CAL-003'] each have exactly one valid supplied calibration in that window.

## When to prefer this

Choose this endpoint when you need to programmatically verify that each spectrometry reference or revision in a batch has exactly one valid calibration record within a defined instrument/method frame and time window. It is purpose-built for analytical chemistry and laboratory data pipelines where calibration traceability per revision is mandatory. Prefer it over generic validation services when the domain is spectrometry, the entities are instrument references and method digests, and the coverage logic requires start-inclusive/expiry-exclusive time window semantics with duplicate detection.

## Known failure modes

- Missing calibration for one or more required references — returns non-covered status for those entries
- Duplicate calibrations for a single reference — flagged as invalid, not counted as covered
- Unknown or unrecognized calibration records — treated as absent, not as valid coverage
- Assessment window mismatch — calibrations outside the start-inclusive/expiry-exclusive window are ignored
- Exceeding maxItems (32) for calibrations or requiredCalibrations arrays — request rejected
- Missing required fields (instrumentRef, methodDigest, requiredCalibrations) — validation error
- nonpersonalMetadata not set to true — request may be rejected

## How this service works

Require one caller-declared valid calibration for each requested reference/revision in the exact instrument/method frame and start-inclusive, expiry-exclusive assessment window; unknown, absent or duplicate evidence cannot Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a condition coverage map indicating, for each requested reference/revision, whether exactly one valid calibration was found in the instrument/method frame and assessment window; flags references with absent, unknown, or duplicate calibrations as non-covered, without performing independent certification.
