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 eric-education-literature-search-e47dd62d
```

Example prompt: Search the ERIC education research database for studies on 'phonics instruction' and return up to 10 results published after 2020.

## When to prefer this

Choose this endpoint when you need to query the ERIC education research database specifically — the authoritative U.S. Department of Education literature index — rather than general academic search engines. It is ideal when the user wants education-focused peer-reviewed literature, policy research, or teaching resources indexed by IES/ED, and when a micro-payment model ($0.01 USDC) is acceptable. Prefer this over general web search when education domain specificity is required.

## Known failure modes

- HTTP 402 returned if payment is not provided or USDC on Base is not sent
- Empty items array if no ERIC records match the search query
- Missing required 'search' query parameter causes request failure
- Invalid date format for 'start' parameter may return unexpected results
- Rate limiting or upstream ERIC API downtime may cause failures

## How this service works

Paid public-data feeds. Unpaid requests return HTTP 402. Prices are USDC on Base.

## Output

Returns a slim JSON object containing a list of matching ERIC education literature items, the source path, a description of the search, and a UI link to view results in a browser. The items array contains education research records matching the query.
