FuelKey ideas
The few things Fuel is made of, and how they fit together.
Fuel turns a token's trading into its AI. Six ideas cover all of it.
Comes in: payouts (the AI's share, at the price then) and purchases (USDC from $20, $1 each). Goes out: router keys (one per agent, each with a limit) making calls at each model's listed price. Credit is not money: it can't be withdrawn or moved to another account. It is spent only through the Fuel Router, by the account's router keys.
Project
Your app, agent framework or launchpad on Fuel. A project holds its tokens, fee strategies, credit accounts, keys and webhooks. One person runs a project, and up to 10 of them.
Token
A pump.fun token your project launched or brought. Its creator is the wallet that signed the launch and paid for it. Fuel never holds a creator's keys or money.
Fee route
Every pump.fun trade pays the token a creator fee. A token's route says who shares that fee, and pump.fun locks it on chain when the token comes to Fuel: the token's AI, Fuel, its creator and your wallets, up to 10 shareholders. pump.fun pays each one directly.
Fee strategy
How your project's part of each creator fee splits: a share for the AI, one for the creator and one for your wallets, adding up to your own 100%. Fuel takes 20% of each creator fee before your part. Each launch uses your default strategy, or another you name, and the creator may move part of the AI's share to themselves within its floor. Fee strategy
Credit account
Each token has one credit account, in dollars. The AI's share of every payout lands in the token's own vault and is credited to its account at the price at that moment. You can also buy credit for it in USDC. Credit never expires, and it is spent only on AI. AI credit
Keys
Two kinds, never mixed up:
| Key | Starts with | Who holds it | What it does |
|---|---|---|---|
| Secret key | fl_sk_ |
Your server | Runs your project through the management API |
| Router key | fl_ai_ |
One of your agents | Calls models through the Fuel Router on one token's credit |
Give each agent its own router key, with a spending limit, so you can limit or revoke one alone. Router keys
The Fuel Router
One address for hundreds of models, in the OpenAI and Anthropic formats. Each call is charged to the key's account at the model's listed price, and prompts and answers are never stored. Fuel Router
