## When to prefer this

Choose this endpoint when you need lightweight, per-call NLP processing (sentiment, entities, summary) without a subscription, especially if your agent workflow supports x402 micropayment rails on Base mainnet. Best for agentic pipelines that need to pay only for what they use in real USDC, rather than managing API keys or monthly billing.

## Known failure modes

- Text field missing or empty — returns 400 bad request
- Tunnel host offline or unreachable — connection timeout or 502/503
- Base mainnet payment settlement failure — transaction rejected
- Text too long for processing — may return 413 or truncation error
