Show HN: Delegare – AI 에이전트가 안전하게 결제하도록 합니다(x402, AP2 – base/USDC 및 Stripe)

Let AI agents pay for things—safely. Give agents real spending power with hard limits they can't override. Users set the rules. Agents execute. Merchants get paid. Max 3¢ per transaction. You set a $30 food budget. Your agent finds a restaurant, places the order, and pays — automatically. You stay in control. It can never spend more than you approved. Set up your spending delegate →Add 5 lines of code. When an agent hits your API, Delegare handles authentication, spending validation, and settlement — via Stripe or USDC on Base. You get paid; they get access. See the integration guide →People are rightfully skeptical when money is involved. Delegare is built on strict boundaries and cryptographic guarantees so your agent can never go rogue. Atomic server-side counters enforce your budget to the cent. If your limit is $10, the agent cannot spend $10.01 — even under concurrent requests. Race conditions are mathematically impossible. Agents never see your card number, private keys, or seed phrase. They hold a signed spending mandate— a scoped, revocable credential that proves what they're allowed to spend. Nothing more. Every mandate is locked to the merchants you explicitly approve. A mandate authorized for an API provider cannot be used at a pizza shop. The agent has no way to circumvent this. Mandates have a strict time-to-live and expire automatically. You can also revoke any active mandate instantly from your dashboard — the agent's access is killed in under a second. One integration, two settlement options. Delegare handles the authorization layer — you keep your existing payment stack. Credit cards, debit cards, and bank accounts. Settle in 190+ countries with Stripe Connect. USDC stablecoin on Coinbase's L2. Instant settlement, no chargebacks, near-zero gas. Delegare is not a payment processor — it's the authorization layer that makes your existing payments agent-ready. Think of it as the identity and permissions middleware between your agent and your money. Your Stripe or USDC setup stays exactly as it is. Delegare sits in front of it, handling agent identity, spending limits, and autonomous payment negotiation. Under $1, the fee drops to 3% — making API micropayments and agent-to-agent transactions commercially viable for everyone. For reference: Stripe's base fee on a $25 transaction is ~$1.03. Delegare's authorization layer costs $0.03. These are different things. Both exist on every transaction.
