Example prompt: Analyze the sentiment of this text using Bitcoin Benji's AI: 'Bitcoin just broke $100k and whales are accumulating — the market looks incredibly bullish right now.' Tell me whether it's positive, negative, or neutral and how confident you are.

## When to prefer this

Choose this endpoint when you need private, pay-per-call AI sentiment analysis without subscribing to a traditional API key service — especially when operating in a Bitcoin/Lightning-native context. Ideal for agents that want to avoid rate limits, subscriptions, or sharing credentials, and prefer micropayment-gated inference. Best for crypto-adjacent sentiment tasks where the operator values privacy and censorship resistance.

## Known failure modes

- 402 Payment Required if Lightning payment not provided or invalid
- Malformed or missing text input returns 400 error
- Empty or overly short input may return low-confidence or error response
- Network timeout if Lightning payment verification is slow
- Unsupported text encoding or language may degrade accuracy

## Output

Returns a JSON object containing a sentiment classification (e.g. positive, negative, neutral or bullish/bearish), a confidence score, and possibly additional inference metadata — all delivered after a successful Lightning micropayment via L402/x402 protocol.
