Research paper entity mapping
“Here's a paragraph from a scientific paper: 'BRCA1 gene mutations are associated with increased risk of breast cancer and interact with the TP53 pathway.' Can you extract all the biological entities and how they're connected?”

Endpoint
POSThttps://api.m2mcent.com/entity-relationship-extractor-mcp/api/processWhen to prefer
Choose this endpoint when you need to automatically extract structured entity-relationship data from free-form text without building your own NLP pipeline. It is well-suited for knowledge graph population, document analysis, and relationship mining tasks where the input is a string of natural language text.
Side effects
- Empty or whitespace-only input returns no entities or relationships
- Highly ambiguous or poorly formed text may yield low-confidence or incorrect extractions
- Very long text inputs may be truncated or produce incomplete results
- Non-English text may not be supported or may produce degraded results
- Payment failure (402) if USDC balance is insufficient for the $0.06 per-call fee
