## 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 omniapi-ai-changelog-endpoint-60134102 -d '<json body>'
```

Example prompt: Search the AI changelog for any recent updates related to 'language model improvements' and show me what changed.

## When to prefer this

Use this endpoint when you need to programmatically search or retrieve AI changelog entries with a natural language query, and you are operating in a pay-per-call x402 crypto payment context. Prefer this over manual changelog browsing when automating release monitoring or integrating changelog data into an agent workflow.

## Known failure modes

- Empty or overly broad query may return no relevant results
- Payment failure via x402 results in 402 Payment Required response
