Bluedoor Overview

Bluedoor is a platform that provides free, hosted data APIs designed to give AI applications, developers, and organizations access to structured, cleaned, and usable real-world data. It transforms scattered public records into ready-to-use datasets across key domains like finance, employment, and law, abstracting away the complexity of data sourcing and normalization.

How to use Bluedoor

Bluedoor is accessed via its public REST APIs. Developers can explore available datasets through the documentation, which includes OpenAPI specifications and client library examples in languages like Shell, Node.js, Python, PHP, and Ruby. To get started, you can query API endpoints for health checks, route catalogs, and source metadata. Specific data queries are made via GET requests to endpoints like /v1/.... The platform provides an interactive API explorer to test requests directly in the browser.

Core Features of Bluedoor

  • Federated API with Consensus: Aggregates data from 26+ provider sources (e.g., Yahoo, Google, Nasdaq for finance) and returns a normalized consensus result when possible, while preserving per-source observations and provenance.
  • Extensive Pre-cleaned Datasets: Offers live, structured data streams including 1M+ US job postings, 26+ financial data providers, SF Superior Court records back to the 1970s, 6.6M H1B LCA filings, and 5.4M licensed contractor events.
  • Developer-Friendly & Free: The public routes are free to use. APIs support CORS preflight and provide clear, structured JSON responses with common evidence envelopes for error handling and status reporting.
  • Transparent Health & Provenance: Includes dedicated endpoints (`/v1/health`, `/v1/source-health`) to check API status and source reliability. The API gracefully handles partial source failures.

Use Cases for Bluedoor

Bluedoor is ideal for building AI models and applications that require real-world data. Use cases include: training machine learning models on job market trends; developing financial analysis tools with multi-source market data; powering legal tech applications with court case history; conducting labor market research with H1B visa filing data; and creating market intelligence platforms for sectors like real estate or contracting.

Advantages of Bluedoor

The primary advantage is eliminating the 'dirty work' of data acquisition. Bluedoor finds, cleans, normalizes, and makes data freely available through a stable API. This saves developers significant time and resources. Its federated approach enhances data reliability through consensus, while maintaining detailed provenance. The explicit free-to-use model lowers the barrier to entry for experimentation and development.
