Stip: a spending policy for software agents
Stip lets an operator authorize a USDC budget that software agents can spend on APIs through HTTP 402 payments.
Field notes
The service places spending controls around an agent’s own EOA rather than describing a custodial wallet: operators specify the agent, caps, recipient allowlist, and expiry, then fund the address with Circle native USDC. Its stated operating surface is narrow—Avalanche C-Chain and Base—and it rejects USDC.e and USDT. The page also reports a $0.01 USDC payment to Tavily on Base as a live example, though the supplied evidence does not independently verify the transaction.
