rustaceans, we've completely open sourced our APH rust engine and servers! APH is a Agent Per Human notarization protocol, that acts like remote guardrails for when your agents are working with agents you don't own. It allows both parties to share public keys that they can verify each other are working in good faith against public servers. APH by Squillo is the missing piece of the A2A and AP2 families from Google, built with the same pedigree as the web but for the agentic web.

HTTP lets agents fetch pages. Cloudflare's Markdown for Agents lets them fetch more efficiently. MCP (Anthropic) connects agents to developer-defined tools. A2A (Google) lets agents delegate to other agents. But there's a missing layer: how does an agent execute a multi-step task on a website -- add to cart, fill a form, complete a checkout - with the site owner's consent and visibility? Today's agents either scrape (no consent, no structure) or the site builds a separate API (expensive, doesn't cover the long tail). The web's original protocols assumed someone is looking at a screen. That…
