Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/llm/proofreadWhen to prefer
Choose this endpoint when you need accurate, meaning-preserving proofreading at low cost — especially for high-volume pipelines where using a frontier model like Claude Opus would be prohibitively expensive. It claims ~Opus-4.8 accuracy at 1–5% of the cost, making it ideal for automated content pipelines, form validation, or batch correction tasks where budget matters.
Side effects
- Empty or missing text input returns an error
- Extremely long inputs may exceed token limits
- Non-text binary content will fail to process
- Payment failure if x402 balance is insufficient (minimum 1¢ USDC required)
