Open Data API

The Open Data API provides public, read-only endpoints for discovery and transparency — no client credentials required for published reference data.

Typical capabilities

• Code lists and reference values
• Conformance / profile metadata
• Participant and software discovery summaries
• Aggregated published price data (supporting fee-comparison style tools)

Example use

Mattertwo's FeeFinder demo compares published prices using open data only — illustrating transparency without a full consent journey.
