# Aayat AI Package Changes

> Aayat AI Package Changes is a paid API for AI agents from aayatai.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Returns release notes, version history, and breaking changes for an npm, PyPI, crates, or Go package between two specified versions.

## Facts

- Endpoint: GET https://aayatai.com/package/changes?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-02

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_i75QVRBFNArEm8M1_jgrY

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 aayat-ai-package-changes-5cb72dad
```

Example prompt: What changed in the hono npm package between version 4.12.0 and 4.13.9? Highlight any breaking changes.

## When to prefer this

Use this endpoint when you need structured release notes and breaking-change extraction for a specific version range of an open-source package across npm, PyPI, crates, or Go modules. Prefer it over generic web search when you want machine-readable output with breaking changes already parsed out, and over the sibling 'changes since a date' endpoint when you know the exact from/to versions rather than a date boundary.

## Known failure modes

- Package not found in the specified ecosystem — returns error or empty result
- Version string not recognized or out of range — may return empty releases array
- No release notes available (private repo or no changelog) — releases may have empty notes fields
- Network timeout fetching GitHub releases or changelog — transient error
- Ecosystem not supported — returns validation error if ecosystem is not npm/pypi/crates/go

## How this service works

Pay-per-use data and tools for AI agents: crypto token safety, prices and wallets, an LLM gateway, web search and documents to Markdown, library docs, package safety and AI model prices for coding agents, company research, news, UK/EU open data and an x402 market guide. Pay per call in USDC on Base or Solana with x402. No account or API key.

## Output

A JSON object containing: the package name, from/to versions, ecosystem, list of releases (newest first) each with version, date, release notes up to 4000 chars, source (GitHub release or changelog), and extracted breaking change lines; plus aggregated breakingHints across all releases, a majorVersionChange boolean, total release count, omitted count, repository URL, and fetchedAt timestamp.
