## What shipped

The x402 discovery routes now provide clearer visibility into pay-per-tool-call execution.

- Discovery documents expose supported payment flows.
- Tool execution endpoints can be enumerated more directly.
- External integrators have a clearer source of truth for payment-gated capabilities.

## Why it matters

Direct discovery reduces integration guesswork and makes EmblemAI easier to index, evaluate, and automate against.

## What this replaces

This replaces a more opaque discovery experience where key pay-per-use behavior had to be inferred from scattered docs or product usage.
