Agentic API Grader by SaaStr.ai

What it does

API Report Card is a free tool from SaaStr.ai that grades any B2B API for how well it works in an agent-first world. It scores APIs across categories like authentication, error handling, documentation, pagination, idempotency, and overall agent-readiness, surfaces a letter grade from F to A+, and generates ready-to-paste prompts that developers can drop into Cursor, Claude, or Replit to fix the issues.

Free AI tools for B2B founders: pitch deck analyzer, VC matchmaking with 400+ investors, valuation calculator, and AI mentor. Powered by SaaStr.

  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…
