Technical details
Endpoint
GEThttps://modelprices.xyz/llm/limit/:modelWhen to prefer
Use this endpoint when you need to quickly check whether a specific AI model can handle a particular task type (vision, audio, function calls, reasoning) or fits within token constraints, and need a single-model answer rather than browsing a full table. Prefer this over the sibling table endpoint when you already know the model ID and want a fast, cheap ($0.002) per-model check.
Side effects
- Unknown model ID returns 404 or empty result
- Model ID typo or unsupported suffix returns no match
- Payment failure (x402) if USDC not provided returns 402 Payment Required
- Rate limiting if too many requests in short period
