# Source Packs - Source Coverage Map

> Source Packs - Source Coverage Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035057/call, status unknown (last checked 2026-10-22).

Compares required source identities and revision/content pins against retained source-pack entries to produce a manifest consistency coverage report.

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 source-packs-source-coverage-map-7ea40fe2 -d '<json body>'
```

Example prompt: Check whether my retained source pack covers all the required sources — I have 3 required sources with their revision and content pins, and I want to know which ones are missing or mismatched. Use public data class and flag it as nonpersonal metadata only.

## When to prefer this

Use this endpoint when you need to verify manifest-level consistency between a list of required source identities (with revision and content pins) and a set of retained pack entries, without requiring actual text retention verification. Ideal for offline, nonpersonal metadata audits of source coverage gaps in pipelines or compliance workflows where only typed metadata is involved.

## Known failure modes

- requiredSources array is empty or exceeds 32 items — validation error
- retainedEntries array exceeds 32 items — validation error
- dataClass not set to 'public' or 'synthetic' — invalid enum error
- nonpersonalMetadata not set to true — request rejected
- Mismatched schema format for source entries — parsing error
- Coverage check timeout if entries are malformed

## How this service works

Compare required source identities and revision/content pins with supplied retained-pack entries. Coverage is manifest consistency, not evidence retention verified against actual text. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns a coverage map indicating which required source identities and revision/content pins are matched by retained pack entries, which are unmatched or missing, and an overall manifest consistency assessment. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
