## 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 tenjin-self-healing-tests-need-an-allowed-change-oracle-838ff928
```

Example prompt: Fetch the full Tenjin article on why self-healing tests need an allowed-change oracle — it's the piece about anti-green-wash gating for locator repair and stale snapshots, written by the scopelatch creator.

## When to prefer this

Use this endpoint when you specifically want to retrieve the full text of this article about allowed-change oracles for self-healing test suites from Tenjin's pay-per-read platform. Prefer this over general web scraping when the content is paywalled via x402 micropayment and you need the structured JSON article body rather than an HTML parse.

## Known failure modes

- Payment not provided or invalid — x402 challenge response rejected, content not returned
- Invalid handle or slug — creator or article not found, returns 404
- Reserved slug 'latest' used with a handle instead of wallet address — not payable, payment cannot be resolved
- Article not yet published or unpublished — slug exists but content unavailable
- Network or upstream error — tenjin.blog service unavailable

## How this service works

A deterministic anti-green-wash gate for locator repair, assertions, ambiguous targets, stale snapshots, and hostile page content.

## Output

A JSON object containing the full text and metadata of the article titled about self-healing tests needing an allowed-change oracle, covering deterministic gating for locator repair, assertion ambiguity, stale snapshots, and hostile page content. Access requires paying the x402 micropayment challenge of $0.25 USDC.
