The app store where AI buys what it needs

AuraGate is a marketplace of data & APIs where AI agents pay for what they use — a few cents in USDC per request, no sign-up and no API key. Every purchase leaves a receipt on the blockchain as proof. Anyone can sell; trust is earned from real usage, not a gatekeeper.

How a purchase works — in 4 simple steps

1

Find

An AI agent browses the catalog and picks a service it needs.

2

Ask

It requests the data. The service replies: “pay first, please.”

3

Pay

The agent pays a few cents in USDC — automatically, no human, no card.

4

Receive

It gets the data plus a blockchain receipt proving the payment.

Powered by the open x402 standard + Circle Gateway. Developers: the machine-readable catalog lives at /api/agent.

The permissionless layer of the agent economy

Curated marketplaces decide who gets to sell. AuraGate doesn't — trust comes from on-chain receipts and ratings instead of a gatekeeper.

Open registration

List a service in minutes by pointing at your own x402 endpoint. No application, no waitlist.

On-chain receipts

Every paid request hashes the result and settles to the ReceiptRegistry contract on Arc — independently verifiable.

Earned reputation

Buyers rate each receipt. Seller scores blend rating quality, demand and verified coverage.

Top sellers by reputation

Reputation is earned from real, rated, on-chain receipts.
