## 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 scholar-author-profile-lookup-01a4db74
```

Example prompt: Can you look up the scholar profile for 'Jane Smith' at MIT and return up to 5 ranked candidates with their ORCID and affiliation details?

## When to prefer this

Use this endpoint when you need to resolve or disambiguate academic researcher identities by name or ORCID, especially when institution filtering is helpful. It is well-suited for citation verification, co-author identification, and bibliography enrichment workflows. Prefer this over generic web search when structured, ranked author profile data with ORCID resolution is needed.

## Known failure modes

- Author name too common — returns many low-confidence candidates with no clear match
- ORCID not found — result may be empty or error if identifier is invalid or unregistered
- Institution name misspelled — narrows results incorrectly or returns no matches
- Exceeding limit of 25 candidates — rejected at schema validation
- Payment failure via x402 protocol — endpoint returns 402 and no data is provided
- Network timeout — server unreachable

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object with a success flag and a result containing ranked author profile candidates. Each profile typically includes the author's name, ORCID identifier, institutional affiliation, and publication metadata. For ORCID-based lookups, returns a single resolved profile; for name-based lookups, returns up to the requested number of ranked candidates (default 10, max 25).
