# Planetary Measurements Condition Coverage Map

> Planetary Measurements Condition Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035258/call, status unknown (last checked 2026-10-20).

Checks declared observational coverage for requested planetary measurement quantities at a specific site and epoch, verifying that each requested quantity has exactly one declared observation matching the specified target, coordinate conventions, time basis, and method.

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 planetary-measurements-condition-coverage-map-985fc26c -d '<json body>'
```

Example prompt: Can you check whether all required quantities — temperature, pressure, and albedo — have declared observations for Mars at the Olympus Mons site, epoch J2000.0, using the ICRF coordinate frame and TDB time scale, from the synthetic dataset, with method digest abc123?

## When to prefer this

Choose this endpoint when you need to verify that a set of planetary or celestial measurement quantities each have exactly one declared observation at a specific site and epoch, with strict matching on coordinate frame, time scale, target, and method. Prefer this over generic data lookup when you need structured pass/fail coverage status per quantity tied to a specific declared record and method digest, rather than retrieving raw data or independent certification.

## Known failure modes

- Missing or ambiguous observations for one or more requested quantities — returns unknown status for those quantities
- Mismatched coordinate frame, time scale, or epoch convention between request and declared record — validation fails
- Invalid or unrecognized targetRef, siteRef, or epochRef — request rejected
- Exceeding 6 required quantities — request rejected with validation error
- nonpersonalMetadata not set to true — request rejected
- Dataset reference not found or inaccessible — coverage check cannot complete

## How this service works

Check one exact declared observation per requested quantity at one site and epoch, with identical target, coordinate conventions, time basis, method and Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a coverage map indicating whether each requested quantity (up to 6) has a declared observation at the specified site and epoch, with pass/fail/unknown status per quantity, reflecting whether the target, coordinate conventions, time basis, method digest, and dataset reference all match the supplied record. Does not perform independent certification — only checks the supplied record's declared observations.
