x402

What it does

x402 turns any AI agent into a self-funded machine. Every HTTP request carries its own payment and settles instantly in USDC via the 402 (Payment Required) status - one round-trip, no cards, no accounts, no human in the loop. Paste any Python logic into the Generator, set a USDC price, and deploy a paid agent in minutes. Try free demo agents (SEO, Gas, Signal, Models, Chat) or wire your own USDC budget to a cron trading agent that pays for itself.

Протокол x402: ИИ-агенты платят за API в одном HTTP-запросе. Установка x402-wallet и запуск агента. Минимализм, без воды.

Протокол x402 превращает оплату API в обычный платёжный ответ сервера. x402-wallet держит ключи. Агент получает данные — сервис получает USDC. Без карт, без OAuth, без офиса. Открытый платёжный протокол для машин. Вместо редиректов и логинов — стандартный HTTP-ответ 402 Payment Required , несущий платёжные инструкции. Клиент (агент) шлёт обычный запрос. Сервер отвечает 402 с ценой и адресом оплаты в заголовке PAYMENT-REQUIRED . Расчёты в стейблкоине, микросуммы, почти нулевая комиссия. Подходит для тысяч вызовов в минуту. Никаких API-ключей вручную, никаких договоров. Есть баланс — есть доступ. Нет баланса — сервер вежливо отказал. x402 спроектирован так, чтобы им пользовался софт, а не вы.…from x402-ai-agent.space

  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…

  Hi guys, am building SecureLend.ai and when working on our underwriting agents (free trial, paid after) I had issues with seamless payment options. Of course I looked at x402 which I believe is a great protocol but not a fan of a) sharing private keys with the agent b) having a human in the loop or c) similar workaround e.g. pre-funded wallets So I started building out a solution. For my use case it was important to not only have stablecoins but also a fiat rail which is now implemented using Stripe. Initially I build a mandate system internally but am very glad and big shoutout to the guys…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
