Headless wins.
Your next user never sees your screens. People decide, and their agents do the work through your API, MCP server and command line.
"Welcome Salesforce Headless 360: No Browser Required! Our API is the UI." — Marc Benioff, Salesforce

You're not building for humans anymore. You're building for their agents.
Your users are starting to delegate to agents. They'll eventually stop using your UI directly.
If you don't have a plan, you won't be ready when agents start deciding which products get used, and which get skipped.
Level 250 helps you build what agents want: APIs, MCP, CLI, Skills, Plugins and Connectors.
Taught by the 3x VP of Product who led Apiary and Swagger, home to 1.3M APIs.

I'm Emmanuel, 3x VP Product, now a founder at Level 250.
If you built or used APIs in the past 15 years, chances are you've used one of my products: I've led some of the most influential API tools: Apiary (550,000+ APIs), Swagger (750,000+ APIs) and Oracle's first Cloud-Native API Gateway. Before that, I built large B2B API programs at Verisk, Moody's, and Precisely.
Today, I advise Fortune 500 CEOs and AI-forward startup founders on API Strategy, Developer Experience, MCP products, and AI agent readiness. I'm also a member of OpenAPI and a featured speaker at apidays and other global technology conferences.

Build what agents want
AI agents are becoming the main user of your product.
Agent experience is to agents what developer experience is to developers: your platform, usable by the agentic tools your customers run.
Test how agents use your product, every release.
Agents fail quietly. Evals and golden prompts show where, so every release gets better.
"The companies that succeed in the agentic era are those that take a thoughtful approach to designing an agentic user experience (AUX)." — Dharmesh Shah, HubSpot
Agents build on your APIs. Make them solid.
Shortcuts in design, governance and security break at agent scale.
"Every company is an API company now, whether they want to be or not." — Sam Altman, OpenAI
If agents can't find you, you don't exist.
Agents pick tools from registries, docs and AI search. Being listed and readable there is the new shelf space.
"If you don't have an API for a feature, it might as well not exist." — Aaron Levie, Box

Our product and design team found value in Emmanuel's vast understanding of the conventions and histories around API design, and we found the final hands-on exercise of speccing and building a working API and gateway practical and empowering. Recommended to product and design teams with a good foundational technical understanding.
