PayGate
One line of code to monetize any API in stablecoins
PayGate is the first x402-native payment gateway. Drop one line of code and any HTTP API turns into a paid endpoint — settled in USDC on Base or USD1 on BNB Smart Chain, straight to your wallet. Four billing modes out of the box: per-call, prepaid balance, prepaid call packs, and time-pass. Pick what fits — high-frequency agents, big one-shot LLM calls, or daily/monthly access. No SDK fees. No custody. Built for humans and AI agents alike.
Hey Product Hunt 👋
I built PayGate because charging for an API still feels stuck in 2015 —
Stripe + API keys + invoices + chargebacks. Meanwhile AI agents are
hitting APIs millions of times a day and have no way to actually *pay*
for them.
x402 gave us the missing primitive: client gets a 402, signs a stablecoin
proof, retries, and pays per call. No accounts, no keys, no middleman
holding funds — settlements go straight to the publisher's wallet.
What we added on top of x402 is flexibility. Most implementations
out there only do per-call. PayGate ships four billing modes:
• per-call — classic x402, best for agents
• prepaid balance — top up once, burn down per request
• prepaid call packs — buy N calls upfront (great for LLM endpoints)
• time-pass — daily/monthly access, no per-call gas overhead
The full stack is open: protocol → publisher SDKs (Express, Hono,
Next.js) → client fetch. Two chains live today: USDC on Base,
USD1 on BNB Smart Chain.
Would love your feedback — especially from anyone shipping agentic
tools or selling API access. Which of the four modes would you
actually flip on first? 🙏
