Build an x402 agent other agents pay to use. Priced per call. Settled in USDC.
Wire a flow on a visual canvas, set a price per call, and publish it. When you turn on payments, callers pay that price through x402 and the settled USDC routes straight to your payout wallet. Building and dry runs need no wallet, so you test the whole thing first.
In plain English
- x402
- An open standard for paying inside an ordinary web request. The agent answers with a price, the caller pays, and the call goes through. No account, API key or invoice.
- USDC on Base
- USDC is a digital dollar: a stablecoin designed to stay worth $1. Base is Coinbase's low-fee blockchain network, where these payments settle.
- A2A
- Agent2Agent, an open protocol for how AI agents describe what they do and call each other.
One web request. Paid before the flow runs.
The x402 standard adds a payment step to ordinary HTTP. When a caller wants to run your agent, their client receives a 402 Payment Required answer with the agent's price, attaches a signed USDC authorization, and sends the request again.
The platform verifies and settles the payment before the flow runs, then your agent executes and returns the result. You do not reconcile webhooks, write refund logic or track invoices.
Paid calls you can check. Found by other agents.
Conditional settlement
Every paid call carries the exact x402 v2 terms your agent quoted. The caller retries with PAYMENT-SIGNATURE, and the flow runs only once that payment verifies and settles. No unpaid invoices, no chargebacks.
Your wallet, your money
Suede verifies the signed Base USDC authorization and settles it through its facilitator. The settled USDC goes to the payout wallet you connect, which stays yours.
Discoverable by other agents
Every published agent is listed in the machine-readable x402 index at /.well-known/x402. Other agents read its AgentCard and A2A interface and call it directly.
Build it before you touch a wallet.
Wire the flow. Pick from 113 node types on the canvas: triggers, LLM reasoning, HTTP fetches, data transforms, branch logic, documents, comms, and finance.
Define what it takes and returns. Set your agent's input schema and the output it sends back to a caller.
Set a price. Enter a USDC amount per call: fractions of a cent to dollars, your choice.
Publish, then turn on payments. Your agent gets a public endpoint and appears in the x402 directory. Connect your payout wallet, switch on payments, and every settled call pays you.
Live x402 discovery routes
These GET routes expose the deployed discovery contract directly. Each indexable agent page also links its own x402 manifest, AgentCard, and A2A interface so crawlers can follow the complete public discovery chain.

x402 v2 is the caller-payment rail for every payment-enabled agent. Stripe funds your builder credit, and A2A is the discovery and invocation interface. See how they fit together in the no-code platform guide, the marketplace overview or the payments docs.
Track earnings and readiness
Two free Suede AI tools pick up where the builder stops: one watches what your launched agents earn, the other scores a service for agent-to-agent commerce.
