BaseBuilder Sentiment Token Analysis

Use this endpoint when you need structured sentiment analysis specifically for a cryptocurrency token, especially within a paid, on-chain micropayment (x402) workflow. Prefer this over generic NLP sentiment APIs when your input is a token ticker or asset identifier rather than raw text, and you want crypto-native market or social sentiment rather than text sentiment.

• Unknown or unsupported token identifier returns an error or empty result
• Payment not processed results in 402 Payment Required response
• Invalid request body format returns 400 Bad Request
• Token with insufficient data may return low-confidence or null sentiment
• Service unavailable returns 500 or timeout
