# Ceramic Measurements - Source Coverage Map

> Ceramic Measurements - Source Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035195/call, status unknown (last checked 2026-10-20).

Binds ceramic lot/method-pinned measurement record references to an exact owner/subject/revision/content/source frame to produce a declared source coverage map.

## 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 ceramic-measurements-source-coverage-map-feea8064 -d '<json body>'
```

Example prompt: I have a batch of ceramic measurement rows and a set of declared sources — can you run them through the source coverage map using the 'synthetic' data class and confirm nonpersonal metadata is set, so I can see how each row binds to its owner/subject/revision/content/source frame?

## When to prefer this

Choose this endpoint when you need to produce a declared source coverage map for ceramic lot or method-pinned measurement records, binding rows to exact owner/subject/revision/content/source frames. It is specifically suited for ceramic measurement data provenance analysis where declared (not independently certified) coverage suffices and data is either public or synthetic and non-personal.

## Known failure modes

- rows or sources arrays exceed 32 items — request rejected
- nonpersonalMetadata not set to true (const) — validation error
- dataClass not one of 'public' or 'synthetic' — enum validation failure
- empty rows or sources arrays (below minItems:1) — validation error
- malformed record references that cannot be pinned to a frame — partial or null coverage output

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

## Output

Returns a declared source coverage map binding each input measurement row to its exact owner, subject, revision, content, and source frame. Output reflects declared pins from the supplied records and is not independently certified or verified source data; it represents supplied-record analysis within the ceramic lot/method-pinned measurement scope.
