Frequently Asked Questions

01

Why is this 300 credits per call?

Wiley finance journals and textbooks are licensed, premium academic content — the most expensive sources to access. The endpoint is priced at 300 credits (≈ $0.30 per call), still far below a single-article paywall or a journal subscription seat.

02

Which sources are covered?

Two licensed Wiley collections: peer-reviewed finance journals and finance textbooks. Both are queried in parallel. (Wiley's Health & Life Sciences collection requires a higher plan tier and is not yet included.)

03

Do I get full article text?

Results return ranked passages with source URLs and citation metadata, suitable for grounding LLM answers and literature review. Full-text access follows Wiley's licensing terms.

04

Date filtering?

Yes. Pass start_date and end_date in YYYY-MM-DD to scope to a publication window.

05

Tool schema for OpenAI / Claude?

GET /api/search/wiley/tool-schema returns ready-to-paste OpenAI function and Claude tool-use definitions.
