Full-text semantic search across authoritative financial theory, empirical research, and applied methodology - including figures, equations, and tables. ## How it works Valyu provides a single **Search API** that lets you search across Wiley's finance content using natural language queries. You send a query, and the API returns relevant passages from Wiley finance papers and books. These results can then be fed directly into an AI model as context for generating answers, analysis, or reports. ``` Your query --> Valyu Search API --> Wiley finance results --> Feed into AI model ``` There is **one API endpoint** to use: the [Search API](/api-reference/endpoint/search) (`POST /v1/search`). You do not need any other endpoints for searching Wiley content. You can test this in four ways (examples below): 1. **No code** - Use the [Search API Playground](#how-to-test-in-the-playground-no-code-required) in your browser 2. **Python** - Use the [Python SDK](#how-to-use-the-python-sdk) (`pip install valyu`) 3. **JavaScript** - Use the [TypeScript SDK](#how-to-use-the-javascript-sdk) (`npm install valyu-js`) 4. **Any language** - Call the [REST API directly](#how-to-use-the-api-directly) with cURL or any HTTP client ## Dataset overview | Property | Value | | -------------- | -------------------------------------------------------------------------------- | | **Source IDs** | `wiley/wiley-finance-books`, `wiley/wiley-finance-papers` | | **Size** | 4,400+ books and 100,000+ papers across 43 journals | | **Coverage** | Quantitative finance, economics, accounting, governance, ESG, management science | | **Data Type** | Unstructured (full-text, figures, equations, tables) | ## Content types | Source | Description | Best For | | ------------------------------ | -------------------------------------------------------------------- | ----------------------------------------------------- | | **wiley/wiley-finance-books** | 4,400+ textbooks and reference works with full chapter-level content | Methodology walkthroughs, frameworks, applied theory | | **wiley/wiley-finance-papers** | 100,000+ articles across 43 peer-reviewed Wiley Finance journals | Empirical evidence, cross-country studies, literature | You can search one or both datasets in a single query. To search both, include both source IDs. ## What you get * **Full-text search** - Search across complete book chapters and journal articles, not just abstracts or metadata * **Rich content types** - Figures, equations, tables, and worked examples are indexed and retrievable alongside prose * **Structured depth** - Access step-by-step methodologies, proofs, case studies, and Excel/R walkthroughs that web sources cannot provide * **Bibliographic metadata** - Authors, ISBNs, ISSNs, titles, and publisher attribution for proper citation * **Semantic ranking** - Results ranked by conceptual relevance to your query, not keyword overlap ## Subject coverage | Domain | Examples | | ----------------------------- | ----------------------------------------------------------------------------------- | | **Quantitative Finance** | Derivatives pricing, real options, stochastic modelling, Monte Carlo methods | | **Financial Economics** | Asset pricing, monetary policy spillovers, market microstructure, banking stability | | **Accounting & Audit** | Fraud detection, revenue recognition, audit analytics, activity-based costing | | **Corporate Governance** | Board composition, ownership structure, agency theory, gender diversity | | **ESG & Sustainable Finance** | Climate risk disclosure, cost of capital, green bonds, post-Paris regulation | | **Management Science** | Decision-making, operations research, HR strategy, innovation management | ## How to test in the playground (no code required) The fastest way to test Wiley finance content is through the **Search API Playground**. No code or SDK installation is needed. Go to [platform.valyu.ai/playground/search](https://platform.valyu.ai/playground/search). You can also open the playground with Wiley datasets pre-selected using this direct link: ``` https://platform.valyu.ai/playground/search?sources=wiley%2Fwiley-finance-books%2Cwiley%2Fwiley-finance-papers ``` If you use the direct link above, the Wiley datasets will already be selected and you can skip to the "Enter a query" step. On the left side of the playground, click **Advanced Settings** to expand the settings panel. This is where you select which datasets to search. Click Advanced Settings to expand the settings panel Click **Included Datasets** at the top of the panel. In the dataset selector, find and select: * **Wiley Papers** (Finance Journals) * **Wiley Books** (Finance Books) Make sure only these two datasets are selected if you want to test Wiley content specifically. You can use the search box to search for "Wiley". Select Wiley Papers and Wiley Books datasets in the dataset selector Type a natural language query in the search box at the top and click **Run**. For example: ``` Black-Scholes options pricing derivation with worked examples ``` The results appear on the right side. Each result shows: * The **title** of the paper or book chapter * A **relevance score** (percentage match) * The **source** (e.g. `wiley/wiley-finance-papers`) * A **content preview** of the matched text * Options to **Copy Citation** and **View Source** Search results from Wiley finance papers showing matched content You can switch between **Results**, **JSON**, and **Table** views using the tabs above the results. At the bottom of the results panel, click **Show Code Snippets** to see the exact code you need to reproduce this search in your own application. Click Show Code Snippets at the bottom of the results panel The Snippets panel opens with ready-to-use code in **Python**, **TypeScript**, and **cURL**. You can copy this code directly into your project - it includes your query, the selected Wiley datasets, and your API key. Code snippet panel showing Python code for the Wiley finance search ## How to use the API directly ### Using cURL ```bash theme={null} curl -X POST 'https://api.valyu.ai/v1/search' \ -H 'Content-Type: application/json' \ -H 'x-api-key: YOUR_API_KEY' \ -d '{ "query": "derivatives pricing Black-Scholes options valuation", "included_sources": ["wiley/wiley-finance-papers", "wiley/wiley-finance-books"], "max_num_results": 10 }' ``` ### Key parameters | Parameter | Value | Description | | ------------------ | ----------------------------------------------------------------------- | ------------------------------------------------------------------------------- | | `query` | Any natural language text | Your search query in plain English | | `included_sources` | `["wiley/wiley-finance-papers"]` and/or `["wiley/wiley-finance-books"]` | Which Wiley datasets to search. Use one or both. **This is the key parameter.** | | `max_num_results` | `1` to `20` | Number of results to return | **Important:** Use `included_sources` to specify the Wiley datasets. If you omit `included_sources`, the search will return results from all available datasets, not just Wiley. ## How to use the Python SDK ```bash theme={null} pip install valyu ``` ```bash theme={null} export VALYU_API_KEY="your-api-key" ``` ```python theme={null} from valyu import Valyu valyu = Valyu() # Search both Wiley finance papers and books response = valyu.search( "derivatives pricing Black-Scholes options valuation", included_sources=[ "wiley/wiley-finance-papers", "wiley/wiley-finance-books" ], max_num_results=10 ) for result in response.results: print(f"Title: {result.title}") print(f"Source: {result.source}") print(f"URL: {result.url}") print(f"Content: {result.content[:500]}...") print("---") ``` For full Python SDK documentation, see the [Python SDK Search guide](/sdk/python-sdk/search). ## How to use the JavaScript SDK ```bash theme={null} npm install valyu-js ``` ```bash theme={null} export VALYU_API_KEY="your-api-key" ``` ```javascript theme={null} import { Valyu } from "valyu-js"; const valyu = new Valyu(); // Search both Wiley finance papers and books const response = await valyu.search( "derivatives pricing Black-Scholes options valuation", { includedSources: [ "wiley/wiley-finance-papers", "wiley/wiley-finance-books" ], maxNumResults: 10 } ); response.results.forEach((result) => { console.log(`Title: ${result.title}`); console.log(`Source: ${result.source}`); console.log(`URL: ${result.url}`); console.log(`Content: ${result.content.slice(0, 500)}...`); console.log("---"); }); ``` For full JavaScript SDK documentation, see the [TypeScript SDK Search guide](/sdk/typescript-sdk/search). ## Example queries Below are example queries that work well with Wiley finance content.
