Get started

Choose your path

Start from the question you have now and move to the smallest set of Blue concepts that answers it.

You do not need to read the documentation in one fixed order. Choose the route that matches the work in front of you.

Read one progressive overview, then process a small document in the Playground.

Start with a complete solution pattern and reveal packages in context.

Learn operations, agent attribution, KYA, Mandates, revocation, and explainable denial.

Understand provider-specific trust, completeness, portal independence, and operator boundaries.

Go directly to Language, Contracts, BEX, Coordination, Mandates, PayNotes, or Agreements.

See how one portal turns Blue documents into practical work and then inspect the technology underneath.
