API Alert

What it does

When Stripe goes down, you find out from a flood of support tickets — not your monitoring tools. API Alert watches your critical third-party APIs and fires instant Slack, Discord and e-mail alerts. Set up in 5 minutes. 14-day trial.

Monitor third-party APIs in real time. Get instant Slack and Discord alerts when Stripe, OpenAI, or any API fails or degrades.

APIAlert monitors real API behavior — not just uptime. Silent failures, schema changes, and degraded responses that return 200 while your checkout breaks. The pre-filled URL returns HTTP 200 with an empty body — a classic silent failure. Stripe's status page shows All Systems Operational. Your checkout silently breaks — every API call returns 200. Your uptime monitor reports green. No 503, no timeout — nothing to trigger an alert. By 9 AM, your support inbox has 47 'payment failed' tickets. Your team debugs your own code for hours. The API was never down. Alert at 2:03 AM: Stripe /v1/charges → HTTP 200 but charges.data is empty APIAlert detected the behavioral change — not just the status…from apialert.io

  Talanoa▲340

  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…
