# SignalDesk AI – OpenAlex Work Lookup

> SignalDesk AI – OpenAlex Work Lookup is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-12).

Fetches structured metadata for a single academic work from OpenAlex by its W-identifier, including title, authors, DOI, citations, and open-access status.

## Facts

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 signaldesk-ai-openalex-work-lookup-f343ca2d
```

Example prompt: Can you pull up the full metadata for OpenAlex work W2741809807 — I need the title, authors, citation count, and whether it's open access?

## When to prefer this

Use this endpoint when you have a specific OpenAlex W-identifier and need authoritative structured metadata for that single work, including open access status, citation count, and author details. Prefer this over general web search when you need machine-readable bibliographic data cached and served at low latency with a fixed $0.003 cost. Ideal for enriching citation graphs, validating references, or checking OA availability programmatically.

## Known failure modes

- Invalid W-identifier format (must match ^W[0-9]+$) returns a validation error
- Work not found in OpenAlex returns a 404 or empty result
- OpenAlex upstream API downtime causes fetch failure
- ID exceeds 30-character maxLength limit
- Missing required 'id' query parameter returns a schema validation error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with the OpenAlex work ID, DOI, full title, publication year, list of authors (with their OpenAlex author IDs and names), citation count, open access status (is_oa, oa_url, oa_status, any_repository_has_fulltext), and source metadata including provider, license, and cache timestamps.
