How this service works

Premier and open-source LLMs — Mistral Large, Medium, Small, Codestral, Magistral reasoning, Pixtral vision, text embeddings, and content moderation.

Output

Returns a JSON object with a `data` field containing the Mistral chat completion (choices, message content, tool calls, usage stats), a `success` boolean, a `payment` object showing settled and authorized USDC amounts, and a `request` object with a UUID and status URL for tracking the metered call.

Example use cases

On-demand code review with Codestral

“Run my Python function through Codestral and ask it to identify bugs and suggest improvements — here's the code: `def fib(n): return fib(n-1)+fib(n-2)`. Use max_tokens 500 and temperature 0.2.”

Structured JSON extraction from raw text

“Send this customer support ticket to Mistral Small and ask it to extract the issue category, urgency level, and customer name as a JSON object: 'Hi, John here — my order #4421 hasn't arrived in 3 weeks, this is urgent!' Set response_format to json_object and max_tokens to 200.”

Multimodal image understanding with Pixtral

“Use the Pixtral vision model to describe what's in this product photo and tell me if there are any visible defects — here's the image URL: https://example.com/product123.jpg. Keep max_tokens at 400.”

Endpoint

When to prefer

Choose this endpoint when you need pay-per-call access to Mistral's model family (including Codestral for code, Magistral for reasoning, and Pixtral for vision) without a Mistral subscription, paying only $0.001 USDC per call via the x402 micropayment protocol. Ideal for agents that need sporadic, metered LLM access billed on-chain, or for workflows that specifically require Mistral's open-source model lineup rather than OpenAI or Anthropic models.

Side effects

Insufficient USDC balance or failed x402 payment authorization — returns payment failure error
Invalid or unsupported model ID — returns model not found error
max_tokens not specified — may be rejected since it's required to bound the metered authorization
Messages array malformed or empty — returns validation error
Rate limits or upstream Mistral API errors — returns 5xx with error detail
Tool definitions malformed — function calling fails with schema validation error
