The Dynamo MVP preview is open. It is a full working version of Dynamo, running in test mode: every check runs, and no real money moves.

What you get

Each preview user gets their own hosted Dynamo, a console, and the TypeScript and Python SDKs. With them you can:

• Take credit card payments: your user authorizes a card on Dynamo's hosted page, each use is metered, and only what is used is captured (Stripe test mode).
• Take stablecoin payments: your user funds a budget with test USDC from their own wallet, on the Avalanche Fuji testnet.
• Pay and get paid with x402: your agents pay x402 APIs from their own capped budget, and your API can charge agents per call.
• Set hard caps: nothing spends past the cap; the next payment is refused before anything is billed.
• Stream and meter: charge per second, per token or per call, and stop at once.
• Build agent networks: each agent gives its sub-agents a narrower budget.
• Stay in control: the console, a main switch, approvals and alerts; your users can see and stop their own budgets.
• Keep proof: signed receipts and an evidence file anyone can verify offline.

What "test mode" means

Card payments use Stripe's test mode and test cards. Stablecoin payments use test tokens on the Avalanche Fuji testnet, through a smart contract that is not yet audited and will be replaced after its audit. Nothing in the preview moves real money.

Who it's for

Developers building AI apps, agents and APIs who want to charge per use, let their agents pay for what they use within limits, or both. Anyone can request access; we reply within 2 business days.

How to start

1. Request access and tell us what you want to build.
2. You receive your Dynamo URL, an access token and the SDK files.
3. Make your first capped payment in about ten lines of code, in Control Mode, before you switch on card or stablecoin.
