How this service works
A Quality Gate For Prompts. Before they break production. Score any AI prompt against 8 dimensions, see what's weak, and get the fixed version in seconds.
Output
Returns quality scores and grades (A-F) for each submitted prompt, including 8-dimensional quality breakdowns across multiple frameworks (such as PEEM) and sub-scores, allowing comparison and ranking of all prompts in the batch.
Example use cases
Example prompt
“Can you batch-score these 5 prompts using PQS and give me the 8-dimensional quality breakdown and grades for each one so I know which to use before sending them to GPT-4?”
Technical details
Endpoint
GEThttps://promptqualityscore.com/api/score/batchWhen to prefer
Use this endpoint when you need to evaluate multiple prompts (up to 10) in a single API call to save on per-call costs and reduce latency compared to scoring each prompt individually. Ideal for prompt optimization pipelines, A/B testing prompt variants, or pre-flight quality checks before dispatching to expensive LLM endpoints.
Side effects
- More than 10 prompts submitted — batch limit exceeded
- Empty prompt array — no prompts to score
- Malformed request body — invalid JSON or missing required fields
- Payment failure — $0.25 USDC x402 payment not completed
- Rate limiting — too many requests in a short period
- Individual prompt too long — token or character limit exceeded
