How to Sell AI API Access and Get Paid in Crypto

FreeTheAI is an AI API marketplace: buyers use one key and one balance for models from many sellers, and each request goes to a provider they follow, usually the cheapest. Sellers are anyone who can serve AI models over an API and has the right to resell that access:

• teams with more API capacity or credits than they use;
• GPU owners running open models such as Qwen, GLM, DeepSeek, or Llama on vLLM, SGLang, or Ollama;
• gateway operators running New API, One API, One Hub, or Done Hub;
• labs that want more buyers for their own models.

1. Create a FreeTheAI account and open Sell in the dashboard.
2. Paste your endpoint's base URL and API key, add your name or company and a contact email (both private), say how many requests a minute it can take, and accept the Seller Terms.
3. FreeTheAI reads your model list and turns each model into a draft, with context and output limits and, when your endpoint publishes them, prices.
4. Set your prices. The pricing helper shows each model's official price, so you can price at a share of it, like 50% or 80%.
5. Submit the drafts. Review usually takes up to a day.
6. Approved models go live. Set a payout address, turn on two-factor authentication, and withdraw your earnings once they are past the hold.

Under Sell > AI agent access you make a token, choose what it may do and when it expires, and copy a setup prompt for Claude Code, Codex, Cursor, or any MCP client. Paste it into your agent and tell it what you want. For Claude Code the setup is one command:

claude mcp add --transport http --scope user freetheai-seller https://mcp.freetheai.org/seller --header "Authorization: Bearer YOUR_SELLER_MCP_TOKEN"

Then ask, for example: "Apply with my endpoint, import my models, price each one at 60% of its official price, and show me the list before you submit." The agent shows you a summary and waits for your yes before anything buyers can see. Changing your endpoint key or payout details needs a code from your authenticator app, and every change is kept in each listing's history.

A buyer's key picks the cheapest provider it follows by default, so a lower price wins more traffic. A price cut applies at once; a rise applies after 24 hours, with the coming price shown to buyers. You can also list a model for free with your own daily limits.

• Serve the model each listing names.
• No advertising: no links, contact details, handles, or your brand in names, descriptions, or replies.
• Do not resell access that comes from FreeTheAI.
• Handle buyers' request content only to answer it.

The Seller Terms are the full version, and the Sell page has fees, payouts, and setup in one place.
