Example prompt: Search the EBI Electron Microscopy Data Bank for cryo-EM maps related to the SARS-CoV-2 spike protein and show me the results.

## When to prefer this

Use this endpoint when you need to search the official EBI Electron Microscopy Data Bank for cryo-EM maps by keyword, protein name, molecule, or any free-text query. Prefer this over generic web search when you need structured EMDB metadata in JSON format for downstream processing in a structural biology or bioinformatics pipeline.

## Known failure modes

- Empty results if query matches no EMDB entries
- Malformed JSON if the upstream EMDB API is unavailable
- HTTP 402 if payment is not provided or fails
- Slow response if the EMDB search index is under load
- Unexpected fields if EMDB changes its response schema

## How this service works
