# Catalyst Measurements - Source Coverage Map

> Catalyst Measurements - Source Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035177/call, status unknown (last checked 2026-10-16).

Binds catalyst measurement records to an owner/subject/revision/content/source frame and maps source coverage across rows and sources for public or synthetic data classes.

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 catalyst-measurements-source-coverage-map-0c72a9ee -d '<json body>'
```

Example prompt: Can you run a source coverage map on these 5 catalyst measurement rows against 3 sources, treating the data as public and confirming no personal metadata is included?

## When to prefer this

Choose this endpoint when you need to formally bind catalyst measurement records to their declared source frames — specifically tying rows to owner, subject, revision, content, and source metadata. Prefer this over generic record-linking tools when working with material-lot or method-pinned catalyst measurement data that requires structured source coverage analysis across public or synthetic data classes.

## Known failure modes

- Rows or sources arrays outside 1-32 item bounds return validation error
- dataClass not set to 'public' or 'synthetic' causes rejection
- nonpersonalMetadata not set to true causes request failure
- Malformed row or source references result in binding errors
- Hash strings not matching declared format return frame mismatch errors

## 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 public material-lot/method-pinned catalyst measurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured source coverage map that binds each input row to its declared sources within an owner/subject/revision/content frame, identifying which records are covered by which sources and flagging any coverage gaps. Includes hash-shaped string declarations for record-source bindings. Not an independent certification of source content.
