# Contract Amendments — Revision Delta Map

> Contract Amendments — Revision Delta Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.021292/call, status unknown (last checked 2026-10-19).

Enumerates exact scope, currency, amount, and effective-time changes between two pinned amendment declarations, validating against tenant/contract frames without semantic or legal analysis.

## 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-revision-delta-map-0cb3c6d5 -d '<json body>'
```

Example prompt: Compare these two contract amendment declarations and map out every exact change in scope, currency, amounts, and effective dates — treat this as public synthetic data and flag anything that doesn't align with the contract frame.

## When to prefer this

Choose this endpoint when you need a precise, typed metadata diff of contract amendment revisions — specifically for scope, currency, amount, and effective-time fields — without requiring semantic interpretation or legal analysis. It is ideal for compliance, audit, and finance workflows that need a structured, offline delta map between two explicitly pinned amendment states, validated against tenant/contract frames, using only non-personal metadata.

## Known failure modes

- Missing or malformed 'before' or 'after' objects cause validation errors
- Invalid or unsupported dataClass enum value returns rejection
- nonpersonalMetadata not set to true (const) causes schema violation
- Tenant or contract frame mismatch returns validation failure
- Expired retained results (beyond 24 hours) are no longer retrievable
- Ambiguous or unpinned amendment declarations may cause incomplete delta output

## How this service works

Enumerate exact scope, currency, amount and effective-time changes between pinned amendment declarations while checking tenant/contract frames. No semantic equivalence or legal analysis. Offline typed metadata only. Retained-result recovery: 24 hours; minimal receipt metadata: 90 days.

## Output

A structured delta map enumerating exact field-level differences between the before and after amendment objects, covering scope changes, currency differences, amount modifications, and effective-time adjustments, along with validation results against the specified tenant and contract frames. Results are retained for 24 hours; minimal receipt metadata is kept for 90 days.
