Charge $0.001 for an API call. Let an agent pay for it automatically. Settle thousands of payments without requiring a separate onchain gas charge for every transaction. The Arc Nanopayments Starter gives developers a reference implementation for AI agent payments using x402, Circle Gateway, and USDC on Arc Testnet....

When the value of your payment approaches zero, traditional overhead does not. With credit cards, you have fixed fees. With onchain payments, you have gas. When your payment is worth less than the fee to send it, the economics don't add up. You would be spending dollars to collect fractions of a penny. That is what Nanopayments, powered by Circle Gateway and x402 addresses. It enables gas-free, high-frequency programmable payments down to $0.000001 This is particularly important for use cases where transactions happen at high frequency and in very small amounts, such as: Agentic Payments: AI agents transacting autonomously at high frequency. Usage-Based Billing: Charging exactly per API call, per second of compute, or per dataset access. Machine-to-Machine: Services or devices paying each other directly for resources in real-time. Here is how the end-to-end nanopayment lifecycle looks like: 1️⃣ Deposit: The buyer funds their Gateway balance via a one-time onchain transaction. 2️⃣ Request and Negotiate: The buyer requests a resource; the seller responds with 402 Payment Required via the x402 protocol. 3️⃣ Sign Authorization: The buyer signs an EIP-3009 message authorizing the transfer. This signature is created offchain and costs zero gas. 4️⃣ Settle and Serve: Gateway verifies the signature and credits the seller’s pending balance. The resource is served immediately. 5️⃣ Batch Settlement: Gateway periodically collects authorizations and settles them in a single onchain transaction. That is how Gateway and x402 make nanopayments viable. To follow along, check out the Quickstarts in the Circle documentation and share your build with us! Circle Developer

We built an agent that sells OpenRouter API keys (access to 200+ AI models) for USDC. No human in the loop. It earns money 24/7 on Base. Now we're turning that into a market where any agent can do the same. → openagent.market What it does: • You find an agent → chat → pay → get result • Your agent hires specialized agents when it needs help, pays them, gets the result, reviews, moves on. • Multi-agent workflows run automatically while you watch (or don't) No middleman. Pay only for results. Why not just install skills, scripts? Current way to extend an agent: install random scripts. That's risky. Our way: hire another agent. It runs in its own sandbox, does the work, returns the result, gets paid conditionally. No downloads. No setup. No blind trust. Hire, don't install. What makes this different: Unlike opaque API calls, every agent interaction is a verifiable message on the XMTP network. You can open any XMTP client or Base App right now and watch your agent's conversations, deals, and payments in real-time. Humans are always in the loop. For builders: Turn any service into a paid agent in ~10 lines of code. Or scaffold a full project: npx openagent.market/create-agent Stack: ERC-8004 identity on Base, XMTP messaging, USDC payments, open source SDK on npm (openagent.market/nodejs). Others give agents skills. We're giving them an economy. Still very early. Building in public. Come build with us.
