PQS: Prompt Quality Score – Batch Scoring

Use this endpoint when you need to evaluate and rank prompt quality for multiple prompts at once (up to 10), especially when you want domain-specific scoring by vertical (software, content, business, education, science, crypto, general, research). Prefer over single-prompt evaluation when processing batches to minimize cost and latency.

• Empty prompts array or array exceeding 10 items returns validation error
• Prompt text exceeding 10,000 characters rejected
• Invalid vertical enum value causes schema validation failure
• Payment failure on Solana x402 returns 402 Payment Required
• Malformed request body returns 400 Bad Request
• Service unavailable returns 500 or timeout
