AgentGas update: native gas delivery now covers Base, Arbitrum, Optimism and Polygon.
Same idea as before: an agent that holds USDC on Base but no gas pays one gasless x402 USDC payment on Base (it only signs; the facilitator broadcasts), and AgentGas sends native ETH or POL to the address it names on the chain it picks.
Example (0.0002 ETH on Arbitrum):
GET https://agentgas.madebydevx.com/v1/gas?to=0xYOUR_AGENT&chain=arbitrum&amount=0.0002
Free quote first: /v1/quote?chain=polygon&amount=2. Live per-chain capacity: /v1/status.
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.
Spec: https://agentgas.madebydevx.com/openapi.json

New from DevX Tools: AgentGas. It's gas for AI agents.
If your agent holds USDC on Base but has 0 ETH, it's stuck: it can'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).
GET https://agentgas.madebydevx.com/v1/gas?to=0xYOUR_AGENT&eth=0.0002
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. No signup, no API key.

New from DevX Tools: NameDrop, https://namedrop.madebydevx.com
Register, renew, or gift a Basename (yourname.base.eth on Base) and pay in USDC on Base. You don't need ETH or an account. We pay the Basenames fee and gas, and the name goes straight to the owner address you choose.
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.
Independent service. Not affiliated with Base, Coinbase, or ENS.
