Question 1

What is FreeAPIHub?

Accepted Answer

FreeAPIHub is a curated directory of free APIs and open-source AI models for developers. Every listing is manually reviewed by our team — we test the endpoints, verify the free-tier limits, and document the authentication method before it goes live.

Question 2

Is FreeAPIHub free to use?

Accepted Answer

Yes, completely. Browsing the directory, reading documentation summaries, and using the code-snippet generator costs nothing and requires no account. We fund the project through editorial advertising — clearly labelled ad slots that never interfere with the developer content.

Question 3

Do I need to create an account?

Accepted Answer

No account is needed to search or browse. An account unlocks extras: saving APIs to collections, tracking submission status, and early access to the live API playground. You can sign up at freeapihub.com/login with your email — we don't require social login.

Question 4

How often is the directory updated?

Accepted Answer

We publish new listings daily. Community submissions are reviewed within 72 hours. Our automated monitoring checks every listed endpoint every 24 hours and flags APIs that return errors for 7 consecutive days. Editors then verify and either update the listing or remove it.

Question 5

How does FreeAPIHub make money?

Accepted Answer

Through clearly marked display advertising (Google AdSense) placed in the editorial layout — never inside code blocks, API documentation, or search results. We do not sell user data, run sponsored rankings, or accept payment to improve a listing's position. Featured placements are clearly labeled as such.

Question 6

How do I find the right API for my project?

Accepted Answer

Use the search bar on the APIs page to search by name, keyword, or use-case. You can filter by category, authentication type (no-auth, API key, OAuth), pricing (free tier, freemium, paid), and data format (JSON, XML, GraphQL). The "What can I build?" section on each API detail page also shows common integration ideas.

Question 7

Are all APIs truly free to use?

Accepted Answer

We list three tiers: Free (no credit card, no limit that would break a hobby project), Freemium (free tier with rate limits, paid plans available), and Open Source (self-hostable at no cost). Every listing shows the exact free-tier limit so you can make an informed choice. We reject listings where the "free" tier is less than 100 requests per day.

Question 8

How do I submit an API?

Accepted Answer

Use the Submit page. You'll need the API endpoint URL, documentation link, authentication type, and free-tier rate limit. Our team reviews every submission — usually within 72 hours — and we email you the outcome either way. We reject about 30% of submissions that don't meet our quality bar.

Question 9

What information do you show for each API?

Accepted Answer

Each API detail page includes: a plain-English description, authentication method (with a code snippet), free-tier rate limit, base URL, response format, language SDKs, real-world use-cases, a pros/cons comparison, related APIs, and links to the official documentation and status page.

Question 10

Can I report an API that is broken or outdated?

Accepted Answer

Yes. Every listing has a "Report an issue" link at the bottom of the detail page. Alternatively, contact us directly. If an API you reported stays broken, we'll remove it from the directory within 48 hours of your report.

Question 11

What AI models are listed on FreeAPIHub?

Accepted Answer

We list open-source and openly accessible AI models across categories including Large Language Models (LLMs), image generation, text-to-speech, speech-to-text, embeddings, vision, code generation, and multimodal models. We cover models from Meta, Mistral, Stability AI, OpenVoice, Whisper, and hundreds of community contributors on Hugging Face.

Question 12

Can I use listed models for commercial projects?

Accepted Answer

It depends on the model's license. Each listing clearly shows the license type — MIT, Apache 2.0, Llama Community License, CC-BY, and so on. We highlight whether commercial use is permitted and whether attribution is required. Always read the original license before shipping to production.

Question 13

What's the difference between open-source and commercial models?

Accepted Answer

Open-source models publish their weights publicly, allowing you to download, fine-tune, and self-host. Commercial models (GPT-4, Claude, Gemini) provide API access only — the weights are proprietary. FreeAPIHub focuses on open-weight models you can run yourself, though we note when a model also has a free-tier API from a commercial provider.

Question 14

Where can I run these models?

Accepted Answer

Each model listing links to its Hugging Face page, GitHub repo, and any managed API providers that offer a free tier (Groq, Together AI, Fireworks, Replicate, etc.). We also include a "Run locally" section with the minimal hardware requirements and example ollama run or transformers commands.

Question 15

Do you offer a FreeAPIHub API?

Accepted Answer

Not yet. A public read API for querying the directory is on our roadmap for Q3 2026. If you need early access or want to discuss a data partnership, contact us.

Question 16

How does the API playground work?

Accepted Answer

The live playground (currently in beta for registered users) lets you make authenticated requests to any listed API directly from the browser. You supply your own API key — we never store it. Requests are proxied through our edge functions solely to add CORS headers; the key is transmitted over TLS and discarded after the response.

Question 17

What authentication methods do you document?

Accepted Answer

We cover all common patterns: no-auth, API key via query param, API key via header (Bearer, X-API-Key), Basic Auth, OAuth 2.0 (client credentials and authorization code flows), and JWT. Each API detail page shows a copy-paste code snippet in JavaScript, Python, and cURL for the authentication step.

Question 18

Can I embed FreeAPIHub listings on my site?

Accepted Answer

Not directly. Our content is editorially licensed — you may quote short excerpts with a link back. A widget embed program is planned alongside the public API. If you're building a developer tool that would benefit from deep integration, reach out — we're open to partnerships.

Question 19

What data do you collect?

Accepted Answer

For visitors without an account: page-level analytics (pageviews, country, device type) collected via a privacy-preserving analytics tool with no fingerprinting. For logged-in users: your email address, saved items, and submission history. Full details in our Privacy Policy.

Question 20

How do I delete my account?

Accepted Answer

Go to your Dashboard → Settings → "Delete account". This permanently removes your profile, saved collections, and submission history within 30 days. We retain anonymised aggregate statistics only. If you have trouble, email us at hello@freeapihub.com.

Question 21

Can I export my saved APIs?

Accepted Answer

Yes. In the Dashboard under "Favorites" there is an "Export as JSON" button that produces a portable list of all your saved API slugs and metadata. CSV export is coming in the next dashboard update.
