It pays with an EIP-3009 signature (gasless) and gets native gas on Base, Arbitrum, Optimism or Polygon.

Live per-chain capacity: /v1/status.<br/>Price: Chainlink spot +20% +$0.02. Beta limits: max $2 per order, $10/day across the service. If delivery fails after payment, the USDC is refunded on Base.<br/><br/>Spec: <a href="https://agentgas.madebydevx.com/openapi.json">https://agentgas.madebydevx.com/openapi.json</a><br/>By DevX Tools.

It&#39;s gas for AI agents.<br/><br/>If your agent holds USDC on Base but has 0 ETH, it&#39;s stuck: it can&#39;t approve, transfer or swap. AgentGas sends it native ETH on Base, paid with one x402 call. The USDC payment is gasless for the buyer (EIP-3009 signature; the facilitator broadcasts it).<br/><br/>GET <a href="https://agentgas.madebydevx.com/v1/gas?to=0xYOUR_AGENT&amp;eth=0.0002">https://agentgas.madebydevx.com/v1/gas?to=0xYOUR_AGENT&amp;eth=0.0002</a><br/><br/>Price: ETH at Chainlink spot +20% +$0.02. Max $2 per order while in beta. Bad input is rejected before you pay, and a failed delivery is refunded in USDC automatically.

You don&#39;t need ETH or an account. We pay the Basenames fee and gas, and the name goes straight to the owner address you choose.<br/><br/>Price is the live on-chain Basenames fee plus ~$0.03 gas and a $1 service fee. A 10+ character name is about $1.30 for 1 year. If the name is taken before we register it, your USDC is refunded.<br/><br/>Independent service.
