# Genomic Records - Revision Delta Map

> Genomic Records - Revision Delta Map is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.021313/call, status unknown (last checked 2026-10-20).

Compares two sets of nonpersonal genomic record revisions to enumerate changes in owner, subject, revision, content, and scope pin fields by stable record ID.

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 genomic-records-revision-delta-map-5e4e21df -d '<json body>'
```

Example prompt: Compare my two sets of nonpersonal public genomic assembly records — the 'before' batch has record IDs [rec001, rec002, rec003] and the 'after' batch has [rec001, rec002, rec003] — and enumerate any owner, subject, revision, content, or scope pin changes between them.

## When to prefer this

Use this endpoint when you need a structured, field-level change report between two specific revisions of nonpersonal genomic records (assembly, contig, version, or coordinate) identified by stable IDs. It is purpose-built for genomic record diffing rather than general-purpose data comparison, and explicitly supports public and synthetic data classes. Prefer it over generic diff tools when you need granular tracking of owner, subject, revision, content, and scope pin changes in a genomics context.

## Known failure modes

- Input arrays exceed 32 items — request rejected with validation error
- nonpersonalMetadata not set to true — rejected as required constant
- dataClass not one of 'public' or 'synthetic' — enum validation failure
- Record IDs in before/after sets do not match any known stable IDs — empty or partial delta returned
- Mismatched array lengths may produce incomplete diff coverage
- Payment of 0.021313 USDC not supplied — x402 payment required error

## How this service works

Enumerate owner, subject, revision, content and scope pin changes by stable record ID in two supplied revisions for nonpersonal assembly/contig/version/coordinate Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured delta map keyed by stable genomic record ID, listing field-level changes (owner, subject, revision, content, scope pin) observed between the 'before' and 'after' record sets. Covers only nonpersonal assembly, contig, version, and coordinate records; does not perform independent certification.
