Pay.sh – Discover, access, and pay for any API autonomously

What it does

The missing payment layer for HTTP — x402 & MPP payment challenges with user-authorized stablecoin signing. # Without pay — you get a 402 curl https://debugger.pay.sh/mpp/quote/AAPL # With pay -- it handles the 402 challenge and returns the response pay curl https://debugger.pay.sh/mpp/quote/AAPL Key Features 💵 Transparent 402 Handling Wrap your CLI ( curl , claude , codex , etc.) -- when an API returns 402, pay detects the payment protocol, prepares the stablecoin transaction, asks the local wallet to authorize and sign it, then retries with the payment proof. Stablecoins deployed to Solana are supported out of the box. pay ships with a built-in MCP server, letting AI assistants request…from github.com

  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…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
