# Tool Context - Duplicate Record Identity Grouper

> Tool Context - Duplicate Record Identity Grouper is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010299/call, status unknown (last checked 2026-10-15).

Groups and deduplicates call-context IDs within the same run, attempt, and contract-digest frame, separating retries and contract versions without performing invocation deduplication or replay prevention.

## 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 tool-context-duplicate-record-identity-grouper-58807bd3 -d '<json body>'
```

Example prompt: Check this batch of up to 32 call-context IDs from our latest pipeline run and group any duplicates by run, attempt, and contract-digest frame — use public data class and confirm nonpersonal metadata only.

## When to prefer this

Use this endpoint when you need to identify and group duplicate call-context records within a precise run-attempt-contract-digest scope, particularly in agentic pipelines where retries and contract version changes need to be distinguished from true duplicates. Prefer this over general deduplication tools when the frame-based grouping (run + attempt + contract digest) is the key axis of analysis and when working exclusively with offline, nonpersonal, typed metadata.

## Known failure modes

- Array of calls exceeds 32 items — validation error returned
- dataClass not set to 'public' or 'synthetic' — enum validation failure
- nonpersonalMetadata not set to true (const constraint) — request rejected
- Empty calls array (minItems:1 violated) — validation error
- Malformed call-context ID format — may silently group incorrectly or return empty groups

## How this service works

Group call-context IDs within an exact run, attempt and contract-digest frame. Separate retries and contract versions; no invocation deduplication or replay prevention is performed. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

Returns grouped sets of call-context IDs that share the same run, attempt, and contract-digest frame, identifying which records are duplicates. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days. No invocation deduplication or replay prevention is applied.
