pay.sh

In plain words

pay.sh is an open source payment infrastructure that enables AI agents to autonomously discover, access, and pay for APIs on a per-call basis. Built in collaboration with Google Cloud, it provides real-time payment processing designed specifically for agent workflows. The tool is aimed at developers building AI systems that need to interact with multiple APIs while handling transactions automatically.

From the sources

In collaboration with Google Cloud, we're building the open source real-time payment infrastructure for AI agents so they can discover and pay per call for any API.

pay.sh lets AI agents and command-line tools call paid APIs with no sign-up, no account, and pay-as-you-go access.

pay.sh handles the payment in one line. No accounts. No keys. No subscriptions. APIs gate access behind an account, subscription, API key, and a credit card. Pay.sh replaces credentials designed for people with pay-per-request payments designed for agents. Search the catalog from Claude, Codex, or the command line. Choose the endpoints that fits the task Send curl or fetch call through pay.sh. The agent gives you a quote for how much the services costs The provider returns the data and the agent continues its work. You only pay for a single call Pay.sh is the easiest way to start selling your service to agents. Run pay server in front of your API and publish to the catalog. Agents discover…from pay.sh

  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…
