About this Gig

AI agents are starting to pay for things on their own API calls, data, 

compute using stablecoins instead of credit cards or subscriptions. 

The protocol behind most of this is called x402 (built on the HTTP 

"402 Payment Required" status code), backed by Coinbase, the Linux 

Foundation, Google, Stripe, AWS, and Visa.


If you're building an API, SaaS product, or AI agent and want to charge 

per request instead of per subscription or let your agent autonomously 

pay for services it uses I can build that for you.


What I offer:

  • Add x402 payment gating to your existing API (server returns a 402, client pays in USDC on Base, access unlocks automatically)
  • Set up AI agent wallets with spending limits and policy controls, so your agent can pay for tools/APIs safely and autonomously
  • Testnet + mainnet deployment, with clear docs so your team can maintain it after handoff
  • Works with agents built on Claude, GPT, or custom agent frameworks


Why work with me:

I come from a smart contract development background, so this isn't my 

first time working with onchain payments, wallets, or Solidity/EVM 

logic x402 sits right at that intersection of Web3 and AI tooling.
