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
