# Contract Amendments — Identifier Crosswalk Audit

> Contract Amendments — Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035022/call, status unknown (last checked 2026-10-18).

Validates clause-ID mapping arrays for unmapped required source clauses, unknown target IDs, and many-to-one collisions in contract amendment contexts — no textual inference, metadata only.

## 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 contract-amendments-identifier-crosswalk-audit-d363a781 -d '<json body>'
```

Example prompt: Audit this contract amendment clause mapping for me — my source clause IDs are [C1, C2, C3], target clause IDs are [T1, T2], and the mappings are [{C1→T1},{C2→T1},{C3→T2}]; the data class is synthetic. Flag any unmapped source clauses, unknown targets, or many-to-one collisions.

## When to prefer this

Choose this endpoint when you need a deterministic, metadata-only audit of clause ID mappings in contract amendments — specifically to catch unmapped required sources, unrecognized target IDs, or many-to-one collisions — without any semantic or textual equivalence inference. Prefer it over general-purpose document comparison tools when working strictly with typed identifier arrays and needing a structured, auditable crosswalk report for legal or compliance workflows.

## Known failure modes

- Exceeding 32-item array limits for sourceClauseIds, targetClauseIds, or mappings returns a validation error
- Omitting required sourceClauseIds or targetClauseIds fields causes request rejection
- Setting nonpersonalMetadata to anything other than true (const) causes schema validation failure
- Supplying a dataClass value outside ['public','synthetic'] returns an enum validation error
- Result retrieval window is 24 hours; requests for recovered results after that window will fail

## How this service works

Check supplied clause-ID mappings for unmapped required source clauses, unknown targets and many-to-one collisions. No textual-equivalence inference. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.

## Output

A structured audit report identifying: (1) required source clause IDs that appear in sourceClauseIds but have no mapping entry, (2) target clause IDs referenced in mappings that are absent from targetClauseIds, and (3) many-to-one collisions where multiple source clauses map to the same target. No textual or semantic inference is performed — results are based purely on the supplied typed metadata.
