x402stock

What it does

Pay-per-call US stock market data API for AI agents. Real-time prices, snapshots, OHLC bars, fundamentals, corporate actions, SEC filings, technical indicators, and news across every US ticker. No API keys, no accounts. Pay per request in USDC via x402 on Base.

Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.

US stocks, options, forex, crypto and on-chain perps, energy commodities, US and global macro, SEC filings, congressional trades, and market sentiment — built for AI agents. No API keys, no accounts. Your agent pays a few cents per request in USDC and gets clean JSON back. Prefer a key over per-call billing? One plan, $99/mo, unlimited calls to every endpoint . x402stock is plain HTTP + the x402 payment standard — any agent with a USDC wallet can pay and call it. No SDK lock-in, no accounts. The highest-value calls on the API — each one bundles or computes what would otherwise take an agent a dozen requests. One call fans out across ~16 sources and an LLM writes the bull/bear case,…from x402stock.xyz

  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▲341

  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…

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
