# Orbital Records - Revision Delta Map

> Orbital Records - Revision Delta Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.021328/call, status unknown (last checked 2026-10-16).

Enumerates owner, subject, revision, content, and scope pin changes between two supplied revisions of stable orbital record IDs, comparing before/after record sets for target/centre/frame/time-scale/solution-pinned orbital data.

## 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 orbital-records-revision-delta-map-57ab1d21 -d '<json body>'
```

Example prompt: Compare my two sets of orbital records — I have up to 32 IDs in the 'before' snapshot and 32 in the 'after' snapshot, both public data class — and enumerate every owner, subject, revision, content, and scope pin that changed between the two revisions.

## When to prefer this

Choose this endpoint when you need to enumerate pin-level changes (owner, subject, revision, content, scope) between two specific revisions of orbital records identified by stable IDs. It is ideal for auditing, change tracking, or validating dataset hand-offs where you have explicit before and after record sets of up to 32 items each and need a structured diff rather than a full record fetch or independent certification.

## Known failure modes

- before or after array exceeds 32-item limit — request rejected
- nonpersonalMetadata not set to true — validation failure
- invalid dataClass value outside 'public' or 'synthetic' enum — rejected
- malformed record IDs in before/after arrays — processing error
- empty arrays on both sides — no delta to enumerate, empty result
- payment failure via x402 protocol — call not executed

## How this service works

Enumerate owner, subject, revision, content and scope pin changes by stable record ID in two supplied revisions for target/centre/frame/time-scale/solution-pinned orbital Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured delta map keyed by stable record ID, listing all pin-level changes (owner, subject, revision, content, and scope) between the supplied before and after revision arrays. The analysis is based on the supplied records only and does not constitute independent certification.
