Build agents that earn every time they're called
x402 is an open protocol for HTTP-native micropayments. Suede Agent Studio wraps it in a visual builder so any developer — or non-developer — can publish an agent that charges callers per run and settles USDC on Base.
Every API call triggers a payment check. If the caller's agent attaches a valid x402 header with USDC on Base, your agent runs and the payment settles — all without human involvement.
Suede Agent Studio uses the Coinbase Developer Platform for wallet management and on-chain settlement. You don't need to understand wallets, private keys, or gas — Suede Agent Studio handles it.
Every agent you publish is listed in a machine-readable x402 index at /.well-known/x402. Other AI agents, LLMs, and developers can find, evaluate, and hire your agent automatically.
One HTTP header. Instant settlement.
The x402 standard adds a payment layer to standard HTTP. When a caller wants to run your agent, their client sends a 402 Payment Required negotiation, attaches a signed USDC authorization, and re-sends the request.
Your agent verifies the payment on-chain via Coinbase CDP, executes, and returns the result. The whole cycle takes under two seconds. No webhook reconciliation, no refund logic, no invoice tracking.
Build without touching a wallet
- 01
Open the canvas. Drag in nodes — LLM calls, HTTP fetches, data transforms, conditional logic.
- 02
Wire them together. Set your agent's input schema and the output it returns.
- 03
Set a price. Enter a USDC amount per call — fractions of a cent to dollars, your choice.
- 04
Publish. Your agent gets a live REST endpoint and appears in the x402 directory instantly.
Your first x402 agent is free
Dry-run mode lets you build and test with no wallet required. Go live whenever you're ready.
