# Free Web Services: the full directory > Free-Web-Services.com is a hand-picked directory of free web services and APIs that developers can add to a website or application. This file holds the whole directory: every category, and every service with its description, whether it needs an API key, what is free, its formats and when its address was last checked. The services are run by their own providers, who set their own terms and limits; the facts below are taken from each service's listing and its documentation. Every address is checked about once a week, and services that stop working or stop being free are removed. Short version: https://free-web-services.com/llms.txt. Each page also has a Markdown version: replace .html with .md, or add index.md to a category address. ## Free AI APIs Page: https://free-web-services.com/web-services/ai/ AI APIs let your own code generate and summarise text, chat, write code, create images and voices, or search and read the web for an AI agent. Every service here has a lasting free plan or free tier, usually with a free API key and a rate limit; check what the free plan allows, and what the provider may do with your data, before you build on it. ### Free LLM and AI Model APIs Page: https://free-web-services.com/web-services/ai/llm/ LLM APIs give your code access to large language models for chat, text generation, summaries, translation, coding help and tool calling. Many follow the OpenAI request format, so one client library works with several providers. The free plans have rate or token limits, and some may use your prompts to improve their models, so read the terms before you send private data. #### Services | Service | API key | Formats | Free use | |---|---|---|---| | [Bytez Model API](https://free-web-services.com/web-services/ai/llm/bytez-model-api.html) | Needed, free | JSON | Free with a free API key and $1 of credit that refreshes every 4 weeks, for open models up to 7B parameters (one request at a time) and closed models; paid plans unlock larger models. | | [Cloudflare Workers AI](https://free-web-services.com/web-services/ai/llm/cloudflare-workers-ai.html) | Needed, free | JSON | The Workers Free plan includes 10,000 'neurons' (Cloudflare's unit of AI compute) per day; requests above that fail until the daily reset, unless you move to the paid plan. | | [Cohere API](https://free-web-services.com/web-services/ai/llm/cohere-api.html) | Needed, free | JSON | Free trial key without a time limit, limited to 1,000 calls per month and a per-minute rate limit; production use needs a paid key. | | [GitHub Models](https://free-web-services.com/web-services/ai/llm/github-models.html) | Needed, free | JSON | Free for every GitHub account, with daily and per-minute request limits per model that depend on your Copilot plan; paid usage is available for more. | | [Google Gemini API](https://free-web-services.com/web-services/ai/llm/google-gemini-api.html) | Needed, free | JSON | Free tier for most text, speech and embedding models with a free API key and rate limits; content sent on the free tier may be used by Google to improve its products, so use the paid tier for private data. | | [Groq API](https://free-web-services.com/web-services/ai/llm/groq-api.html) | Needed, free | JSON | Free plan with a free API key and rate limits per model; paid plans for higher limits. | | [Kilo AI Gateway](https://free-web-services.com/web-services/ai/llm/kilo-ai-gateway.html) | Not needed | JSON | Free without a key for models tagged :free, up to 200 requests per hour per IP address; other models need a Kilo API key and paid credits. | | [OpenRouter](https://free-web-services.com/web-services/ai/llm/openrouter.html) | Needed, free | JSON | Free models are limited to 20 requests per minute and 50 per day, or 1,000 per day once you have bought at least 10 credits; other models are paid per token. | | [OVHcloud AI Endpoints](https://free-web-services.com/web-services/ai/llm/ovhcloud-ai-endpoints.html) | Not needed | JSON | Free without a key at up to 2 requests per minute per IP address and per model; an API key from a paid Public Cloud project raises this to 400 requests per minute, billed per token. | | [Requesty](https://free-web-services.com/web-services/ai/llm/requesty.html) | Needed, free | JSON | Free with a free API key for models marked free, up to 200 requests per day, no credit card; other models are paid per token. | | [Vercel AI Gateway](https://free-web-services.com/web-services/ai/llm/vercel-ai-gateway.html) | Needed, free | JSON | Free with a free API key and a monthly included credit for a subset of models, at lower rate limits; Vercel may ask for a payment method before the free credit can be used. | | [Z.ai API (GLM Flash models)](https://free-web-services.com/web-services/ai/llm/z-ai-api.html) | Needed, free | JSON | Free with a free API key for the Flash models: GLM-4.7-Flash, GLM-4.5-Flash and GLM-4.6V-Flash. | #### Questions **Which free LLM and AI model APIs work without an API key?** Kilo AI Gateway and OVHcloud AI Endpoints work without a key, according to their documentation.

Together they are the retrieval part of retrieval-augmented generation (RAG). Check the free token allowance and whether your vectors stay compatible when a model is updated. #### Services | Service | API key | Formats | Free use | |---|---|---|---| | [Pinecone API](https://free-web-services.com/web-services/ai/embeddings/pinecone-api.html) | Needed, free | JSON | Free on the Starter plan: up to 2 GB storage, 1 million read units and 2 million write units a month, 5 million embedding tokens a month per hosted model and 500 rerank requests a month. | | [Qdrant Cloud](https://free-web-services.com/web-services/ai/embeddings/qdrant-cloud.html) | Needed, free | JSON | Free forever: one cluster with 1 GB RAM and 4 GB disk and free small embedding models, no credit card needed; unused free clusters are suspended after a week and deleted after four weeks. | | [Upstash Vector](https://free-web-services.com/web-services/ai/embeddings/upstash-vector.html) | Needed, free | JSON | Free plan with up to 10 indexes, 1 GB of data and 10,000 queries and updates a day; pay as you go after adding a card. | | [Voyage AI API](https://free-web-services.com/web-services/ai/embeddings/voyage-ai-api.html) | Needed, free | JSON | Free with a free API key for the first 200 million tokens per account on most current models; paid per token after that. | #### Questions **Are these embedding and reranking APIs really free?** The services here can be used without paying, at least on a free plan or free tier, often with limits such as a number of requests per day or non-commercial use only.

All components of Uploadcare, from widget to CDN, work seamlessly together, require almost no configuration and allow maximum flexibility exactly when you need it. Uploadcare consists of three components: Upload, Storage and CDN. Upload interfaces, such as browser widget and components for mobile applications, allow users to upload files. Whenever a file is uploaded, your application receives CDN link or file UUID which can be used by API to get detailed information about the file, store or copy it. Any file you’ve stored is available via CDN, which delivers original files to your users, as well as versions of them tailored for your needs: thumbnails and whatnot. In order to use Uploadcare, you will need to sign up. Registration is free (no credit card required) and very easy, in fact, you can sign up with your Google or GitHub account, so you don't have to think up a new password. After successfully completing your registration, you will get public and private keys for your project that allow you to interact with the service. - API key: Needed, free - From the browser: Yes (CORS) - Formats: JSON, XML - Interface: REST, HTTP-GET, Javascript - Provider: uploadcare.com - Last checked: Working on November 2nd, 2026 ### Free Security APIs Page: https://free-web-services.com/web-services/web-development/security/ Security APIs check links, files, domains, passwords and certificates: whether a URL or file is malicious, whether a password has leaked, who owns a domain and how well a site's HTTPS is set up.

Most keyless services ask you to keep the number of requests reasonable, and some ask for a User-Agent that names your app. **Are these testing and mock data APIs really free?** The services here can be used without paying, at least on a free plan or free tier, often with limits such as a number of requests per day or non-commercial use only. The table above quotes what each service says about its free use; check the provider's own terms before you rely on it. **How up to date is this list?** The address of every service is checked about once a week, and services that stop working or stop being free are removed.
