## When to prefer this

Choose this endpoint when you need fast, pay-per-call keyword extraction without managing your own NLP infrastructure. It is well-suited for agents that need to tag, index, or summarize textual content on demand. Prefer this over general-purpose LLM prompting when you want a dedicated, cost-predictable extraction pipeline billed in USDC via x402 on Base chain.

## Known failure modes

- Empty or missing text input returns an error or empty keyword list
- Very short inputs (single words or fragments) may yield poor or no keywords
- Extremely long texts may be truncated or time out
- Non-English text may produce degraded keyword quality or errors
