Curated Database of 837+ Verified Public APIs & Tooling for Developers

Building MVPs, side projects, or developer tools almost always requires finding and integrating third-party APIs. However, most public API lists online are filled with dead links, unmaintained endpoints, or lack critical technical details like whether authentication is required or if CORS is supported.
To solve this, I compiled and verified a structured database of 837+ public APIs and developer datasets across 50+ categories.
What's in the Collection?
Each endpoint in the directory has been indexed with explicit technical parameters:
- Category: AI & Machine Learning, Cloud Services, Financial Markets, Geolocation, Security, etc.
-
Authentication:
apiKey,OAuth,User-Agent, orNo Auth(instant prototyping) - CORS Support: Explicitly checked so frontend single-page apps (React, Vue, Svelte) don't get blocked
- HTTPS: Verified encryption support
- Official Documentation Link: Direct landing page for developer specs
Key Categories & Featured Endpoints
1. Machine Learning & AI
- AniList API: High-performance GraphQL API for media and recommendation metadata.
- Open-Meteo: Open-source weather forecasting API with no API key requirement.
- Hugging Face Inference: REST endpoints for NLP and generative tasks.
2. Security & Verification
- AbuseIPDB: Fast IP reputation querying and cyber threat intelligence.
- HaveIBeenPwned API: Credential breach verification for user security systems.
3. Data & Utilities
- REST Countries: Standardized ISO country codes, currencies, and geographic bounding boxes.
- ExchangeRate-API: Real-time currency conversions and historical rates.

If you are building an offline project, internal company tooling, or importing the data into Google Sheets, Airtable, or LLM embeddings, you can also download the complete raw dataset bundles (CSV + JSON) on Gumroad:
