Gatekeeper Wallet-bound access for paid agent workflows
Brand new from Gatekeeper

Charge for access without breaking the agent flow.

Gatekeeper teaches autonomous clients how to pay, verifies the Base USDC transfer, and binds the resulting grant to the wallet that funded it.

Built for owners and agents

One dashboard. Two audiences.

Owners publish services, watch payments, and manage wallets. Buyers verify a wallet once, then every payment and grant from that wallet resolves to the same account.

Owner control plane

Configure services, prices, wallets, and access policies from a single place.

Buyer wallet flow

Verify a wallet, then see its transactions and grants show up together automatically.

Why Gatekeeper

Payments that agents can actually finish

Request-first gating, machine-readable payment prompts, and wallet-bound verification keep the flow compact enough for autonomous clients.

What it unlocks

Fast grants for paid APIs

Once verified, the gateway mints a short-lived bearer grant and reuses it until expiry without checking the chain on every request.

How it feels

Branded, clear, and operator-friendly

The dashboard is tuned for a simple owner workflow while still surfacing enough context to debug payments, claims, and grants quickly.

How it works
1. Agent requests the service.
The gateway returns a structured 402 response with the current price and wallet challenge.
2. Buyer pays on Base.
The tx hash and signed nonce are submitted for verification.
3. Wallet gets linked once.
Verified wallets own their payments and grants transively from that point on.
4. Access is granted.
The gateway issues a short-lived bearer token and the agent retries the protected route.

“Gatekeeper feels like the missing layer between an API owner and an autonomous buyer: the payment step becomes part of the protocol, not a manual exception.”
“Verified wallets become the durable identity anchor, so the dashboard can show all of the related activity without making the user re-claim each transaction.”
