## 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 suverse-openalex-concepts-search-7bffa52f -d '<json body>'
```

Example prompt: Search the OpenAlex scholarly graph for concepts matching 'transformer neural networks' and give me the top ranked results with their concept IDs and metadata so I can use them for a literature review.

## When to prefer this

Choose this endpoint when you need to map free-text research keywords to canonical scholarly concept identifiers in the OpenAlex knowledge graph, especially for literature review automation, academic metadata enrichment, or citation graph analysis. It is ideal when you do not have an OpenAlex API key and want a pay-per-use proxy with no authentication setup. Prefer this over direct OpenAlex API calls when operating in an agentic context that supports x402 micropayments.

## Known failure modes

- No matching concepts found for highly niche or misspelled keywords
- Payment failure (x402) if USDC balance is insufficient or payment not processed
- Empty or ambiguous keyword produces low-quality or irrelevant ranked results
- Rate limiting or proxy errors from the underlying OpenAlex API
- Network timeout if OpenAlex backend is slow or unavailable

## How this service works

Search the OpenAlex open scholarly graph for concepts by keyword, no key. Returns ranked matches with identifiers and metadata. For AI agents doing literature review, research enrichment, and citation analysis.

## Output

Returns a ranked list of scholarly concept matches from the OpenAlex open knowledge graph, each including a unique concept identifier (OpenAlex ID), the concept name, and associated metadata such as relevance score, hierarchy level, and descriptive information useful for literature review and research enrichment workflows.
