## When to prefer this

Choose this endpoint when you need to extract structured entity information from unstructured text without managing API keys, paying per call in USDC on Base via the x402 protocol. Ideal for agents needing lightweight NLP entity extraction as part of a pipeline, especially when integrating with other ApexAPI endpoints covering crypto, finance, or social media data.

## Known failure modes

- Empty or missing query field returns an error or empty entity list
- Extremely long text may be truncated or exceed processing limits
- Ambiguous or highly domain-specific terms may be misclassified
- Non-English text may produce poor or no entity recognition results
- Malformed JSON request body returns a 400-level error
- Payment failure in USDC on Base results in 402 response and no processing
