Install any OpenAI-compatible SDK, point it at api.aimlapi.com/v1, and set the model to inference-net/schematron-v2-small.
import requests

r = requests.post(
    "https://api.aimlapi.com/v1/chat/completions",
    headers={"Authorization": "Bearer " + AIMLAPI_KEY},
    json={
      "model": "inference-net/schematron-v2-small",
      "messages": [
        {
          "role": "user",
          "content": "Hello!"
        }
      ]

)
print(r.json())
const r = await fetch("https://api.aimlapi.com/v1/chat/completions", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.AIMLAPI_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "model": "inference-net/schematron-v2-small",
    "messages": [
      {
        "role": "user",
        "content": "Hello!"
      }
    ]
  }),
});

Frequently asked questions

Schematron V2 Small is an HTML-to-JSON extraction model from Inference.net that turns messy HTML into clean, schema-conforming JSON. It is built for structured extraction rather than general chat.

It takes raw HTML plus a JSON schema, such as Pydantic, Zod, or JSON Schema definitions. Extraction instructions are carried through the schema rather than through a system or user prompt.

It returns schema-conformant structured output in JSON. Inference.net describes the output as valid JSON by construction and strictly schema-compliant.

Yes, it supports structured output. The model is designed to return validated JSON that conforms to the provided schema.

Yes, the provider catalogue lists streaming as a capability for this model. The model is also described as having strict JSON mode for schema-compliant output.

It is targeted at web scraping, product data ingestion, financial document parsing, and search-augmented pipelines that need reliable structured output. Inference.net also describes it as useful for complex schemas and long pages.

Do not write a conversational prompt; send the schema and the HTML instead. The schema acts as the interface for extraction.

No. It is a specialized extraction model focused on HTML-to-JSON conversion and schema-constrained decoding.

It is intended for messy HTML and long pages that need clean typed JSON extraction. Inference.net says it delivers frontier-level extraction quality on complex schemas and long pages.

Developers usually look for whether they need reliable HTML-to-JSON extraction, schema-constrained output, and structured data pipelines. They also check that their workload fits a model built for extraction rather than open-ended generation.
