## When to prefer this

Use this endpoint when you need to retrieve specific EPUB content units from The Volcanic Engine by concept reference for personal study or internal organizational reading, and require exact edition pinning. Not suitable for real-time hazard forecasting, factual scientific certification, or general web-based volcanic information lookup.

## Known failure modes

- Invalid or unsupported unit identifiers return an error
- Concept array exceeds 8 items or is empty — validation error
- Data class value not in allowed enum returns 400
- Requesting more than 3 units results in schema validation failure
- Payment failure via x402 prevents content delivery
- Unavailable edition pin returns not-found error

## How this service works

Deliver up to three current selected-EPUB units of The Volcanic Engine with caller-declared concept references. Exact edition pins; personal/internal reading only; no hazard forecast or factual certification.

## Output

Returns up to three EPUB content units from a pinned edition of The Volcanic Engine, each matched to the caller-declared concept references. Content is scoped for personal or internal reading only; no hazard forecasting or factual certification is included.
