Welcome to the RAE API Organization. We provide tools and resources for developers who want to interact with the Spanish language programmatically. Our flagship project, rae-api.com, is an unofficial API for querying the Real Academia Española (RAE) dictionary.
- rae-api.com — Unofficial API for the RAE dictionary: definitions, conjugations, reverse search, word of the day, polysemic words and locutions.
- go-rae — Go client library for the RAE API.
- rae-tui — Terminal-based interface for exploring the dictionary.
- rae-raycast — Raycast extension for quick lookups.
- rae-mcp — Model Context Protocol server for LLM integration.
Due to continuous attacks (DDoS, abusive scraping) affecting service quality, we've implemented rate limiting. API keys are free — this isn't monetization, it's abuse protection.
| Tier | Requests/min | Requests/day | How to get it |
|---|---|---|---|
| Free | 10 | 100 | No API key needed |
| Developer | 60 | 5,000 | Request for free |
| Extended | 300 | 50,000 | Request (high-volume projects) |
- Fuzzy search for partial matches and derived words
- Inverse indexing for definition-based lookups
- Improved parsing for RAE's HTML changes
The RAE hasn't provided a public API or database for their dictionary. Many developers have struggled to find a reliable way to query Spanish words programmatically. This project fills that gap.
Is this official?
No. This is an unofficial API with no affiliation to the RAE.
Can I use this for my project?
Yes. It's free for everyone. Donations help keep the servers running: Ko-Fi.
What if the RAE changes their website?
The API relies on scraping. Changes to their HTML can temporarily break features. We store data locally to ensure continuity.
If you find this useful, consider supporting the project:
- Ko-Fi
- Share rae-api.com with others
