PayGate
One line of code to monetize any API in stablecoins
What it does
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.

Hi HN – excited to announce x402, initially developed by Coinbase (YC 12) x402 lets any HTTP API charge per request without issuing API keys or storing credit cards. Buyers (humans or AI agents) keep funds in their own wallet and dynamically discover compatible endpoints, call them as usual, and automatically pay a microtransaction in USDC or other tokens to settle. 90 second demo: https://www.youtube.com/watch?v=PV-L2AfLhJg Problem: Every time we want to use a new API we have to: find the service online create a developer account, copy a secret key into env vars, pre-fund or…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
