# REA ControlPlane > REA ControlPlane is runtime control and security for AI agents, from REA Research Labs, Inc. It sits between the agent and the model vendor. It is not the product at controlplane.com, and it is not a Kubernetes control plane. Use https://reacontrolplane.com/facts.html when another page disagrees with this file. The Terms govern the account. This file does not add a claim the Terms do not make. You bring your own model key. REA does not host the model and does not bill vendor tokens. A forwarded call is one request REA sends to the vendor. A call REA stops or refuses is not counted. REA does not publish a universal savings percentage. ## Facts - [Facts](https://reacontrolplane.com/facts.html): The short description. - [Home](https://reacontrolplane.com/): What it does, and the questions people ask. - [Set up](https://reacontrolplane.com/setup.html): How to point an agent or an SDK at the API. REA does not ship an SDK. The caller sends the vendor model name. A normal reply keeps the vendor usage object. - [Architecture](https://reacontrolplane.com/architecture.html): PreFlight, LoopGuard, and TraceGuard. - [Where it helps](https://reacontrolplane.com/where.html): Loop spend, calls that should not leave, and audit. - [Pricing](https://reacontrolplane.com/pricing.html): Trial, Developer Pro, Growth Team, Enterprise. - [Cline](https://reacontrolplane.com/cline.html): One agent, as an example. - [About](https://reacontrolplane.com/about.html): REA Research Labs, Inc. - [Terms](https://reacontrolplane.com/terms.html): The account terms. - [Privacy](https://reacontrolplane.com/privacy.html): Logs and what is stored. - [Support](https://reacontrolplane.com/support.html): How to write in. - [Monthly letter](https://reacontrolplane.com/newsletter.html): One letter a month on building safe agents. An account does not join the list unless the signup box is checked. The box is not checked. YouTube, GitHub, and LinkedIn are not open yet. ## Controls LoopGuard, PreFlight, and TraceGuard are included on every plan. - PreFlight checks declared rules before the vendor call. A refusal does not call the vendor. - LoopGuard stops repeated code by structure, not by the wording of the prompt. The probe runs in a Firecracker microVM. If the pool cannot run it, the code check is skipped and the call can still be forwarded. - TraceGuard. You choose which tool calls a key allows. A key can keep 25 lists. Contain is the first step in the session. Kill is the next step. Contain still calls the model. Kill returns HTTP 403 traceguard_killed and ends the hop. The console names the step. Until the list is locked, the call is not stopped. The receipt has no message content and no tool arguments. LoopGuard is the cost control. ## What it is not - Not the product at controlplane.com. - Not a Kubernetes control plane. - Not a model. It does not train, and it does not rewrite the vendor's answer. - Not a partner of OpenAI, Anthropic, Google, xAI, Mistral, DeepSeek, Groq, Together, Fireworks, Amazon, OpenRouter, or of any coding agent named on the site. ## Account and plans Signup asks for a name, work email, company, and a password. Phone and role are optional. Stripe collects the billing address. The password is stored only as a hash. The key is shown once. The console sign-in is the email and the password. The key is how an agent calls the API. An account does not join the monthly letter unless the signup box is checked. The box is not checked. A checked box sends a confirm message and does not create the key. - Trial: Stripe collects the payment method. REA does not store the card number. The card is not charged during the 7 days. Calls stop at 2,000 forwarded calls, and the 7 days still run. 60 requests a minute. When the 7 days end, that card is charged for the first month of the plan chosen at signup, unless you cancel first. - Developer Pro: $79 a month, or $758.40 a year paid in full. 50,000 forwarded calls a month. 300 requests a minute. - Growth Team: $299 a month, or $2,870.40 a year paid in full. 250,000 forwarded calls a month. 1,200 requests a minute. - Enterprise: no set price and no published allowance. A separate contract. elijah@reacontrolplane.com. Prices are in US dollars. Tax is added on top where it applies. There are no refunds. The public site is https://reacontrolplane.com. The API is https://api.reacontrolplane.com. ## Controls Each control has a page. All three are on every plan. - [Controls](https://reacontrolplane.com/controls/): The three, together. - [PreFlight](https://reacontrolplane.com/controls/preflight.html): Declared rules before the vendor call. A refusal does not call the vendor. - [LoopGuard](https://reacontrolplane.com/controls/loopguard.html): Repeated code, by structure. The probe runs in a Firecracker microVM. - [TraceGuard](https://reacontrolplane.com/traceguard.html): You choose which tool calls a key allows. A key can keep 25 lists. Contain is the first step in the session. Kill is the next step. Contain still calls the model. Kill returns HTTP 403 traceguard_killed and ends the hop. The console names the step. No message content and no tool arguments. ## Agents These use the chat door, https://api.reacontrolplane.com/v1. They are not partners of REA. - [Agents](https://reacontrolplane.com/agents/): Hermes, Cline, Continue, Cursor, OpenCode, Kilo Code, Roo Code, Aider, Goose, Qwen Code, Zed, and Pi. - [Cline](https://reacontrolplane.com/cline.html): The step-by-step gallery. ## CLIs These do not share a path. - [CLIs](https://reacontrolplane.com/clis/): Claude Code, Codex CLI, and Gemini CLI. - [Claude Code](https://reacontrolplane.com/clis/claude-code.html): Messages. No /v1 on the base URL. - [Codex CLI](https://reacontrolplane.com/clis/codex.html): Responses. wire_api stays responses. - [Gemini CLI](https://reacontrolplane.com/clis/gemini-cli.html): Gemini. The base URL is the origin only. ## Paths The model id picks the host. REA does not bill the Bedrock account or the OpenRouter account. Neither company is a partner of REA. - [Paths](https://reacontrolplane.com/paths/): Bedrock's three routes, and OpenRouter. - [Amazon Bedrock](https://reacontrolplane.com/paths/bedrock.html): One Bedrock API key. The prefix is bedrock/. Invoke and Converse are not translated. - [Bedrock Chat Completions](https://reacontrolplane.com/paths/bedrock-chat.html): POST /v1/chat/completions. - [Claude on Bedrock](https://reacontrolplane.com/paths/bedrock-messages.html): POST /v1/messages. The chat path does not carry these models. - [Bedrock Responses](https://reacontrolplane.com/paths/bedrock-responses.html): POST /v1/responses. wire_api stays responses. - [OpenRouter](https://reacontrolplane.com/paths/openrouter.html): Chat only. The prefix is openrouter/ and it is not sent. ## Memberships REA Research Labs is a member of the NVIDIA Inception program and of AWS Activate. Membership is not a product partnership and not an endorsement. Amazon Bedrock is still not a model partnership. - [Memberships](https://reacontrolplane.com/memberships.html) ## Programs A confirmed program price replaces the list price. The allowance does not change. You still pay the model vendor. REA confirms each one and can end it. - [Programs](https://reacontrolplane.com/programs/) - [Startups](https://reacontrolplane.com/programs/startups.html): 30% off Developer Pro or Growth Team. $55.30 a month or $663.60 a year. Growth Team is $209.30 a month or $2,511.60 a year. The percent comes off the monthly price, or off twelve months at that price. It is not also taken off the prepaid annual price. - [University clubs](https://reacontrolplane.com/programs/university.html): Developer Pro at no charge for the REA plan, for an active university AI club. No card. No trial clock. 50,000 forwarded calls a month. REA does not pay the model vendor. - [Medicine](https://reacontrolplane.com/programs/medical.html): Investigators and clinicians in medical research or treatment may apply for a 50% reduction on the REA plan. Work in neuroendocrine oncology or radiation medicine, including treatment, may qualify for a full waiver of the REA fee. Model charges remain with the vendor. REA does not diagnose or treat.
