What is Cloudflare Clef?
Cloudflare Clef lets teams using agents classify requests and provide structured decisions. It analyzes text, images, and videos, assigns probabilities, and assesses incident urgency and severity.
According to its documentation, Cloudflare Clef lets you:
- classify a request into predefined categories
- assign a probability to each possible response
- assess the urgency and severity of an incident
- analyze text, images, and videos
- provide structured decisions to an agent
We file it under Model APIs and platforms, the category of tools to access models through an API, and it also overlaps with developer tools and aI agent builders. The category lists 23 verified tools on this site.
The publisher is Cloudflare, Inc., based in United States. The service launched in 2026: it is still very new.
Who is it for?
It is mostly useful to these profiles: developers and data analysts. The need it covers is simple to state: access models through an API.
Cloudflare Clef is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you want to read the code or host it yourself
The best test is a concrete case from your daily work: if the tool does not beat your current method within a week, move on to an alternative.
How much does Cloudflare Clef cost?
Pricing model: open source (public code). A free plan is offered, usually limited in volume or features.
The first paid plan costs $0.04 pay as you go (Clef-flash, per million input tokens; no output token cost. Clef standard: USD 0.24 per million input tokens), according to the pricing page, checked on October 24, 2026.
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: yes (details on the official site). Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Cloudflare Clef runs on: web browser and API.
Interface languages: English.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
