langextract-api
Local HTTP API on 127.0.0.1 wrapping google/langextract: structured extractions from unstructured text with optional character grounding.
Environment
| Variable | Required | Description |
|---|---|---|
LANGEXTRACT_SERVICE_TOKEN |
no | If set, every request must send Authorization: Bearer <token>. |
LANGEXTRACT_API_HOST |
no | Bind address (default 127.0.0.1). |
LANGEXTRACT_API_PORT |
no | Port (default 37141). |
LANGEXTRACT_API_KEY |
no | Used by LangExtract for cloud models (e.g. Gemini) when the client does not pass api_key in the JSON body. See upstream docs. |
Endpoints
GET /health— liveness.POST /extract— run extraction. JSON body matches LangExtractextract()parameters where applicable:text,prompt_description,examples,model_id, optionalmodel_url(Ollama),extraction_passes,max_workers,max_char_buffer,api_key,fence_output,use_schema_constraints.
Example examples item:
{
"text": "ROMEO. But soft!",
"extractions": [
{
"extraction_class": "character",
"extraction_text": "ROMEO",
"attributes": {}
}
]
}
Run
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
export LANGEXTRACT_SERVICE_TOKEN='…'
uvicorn app.main:app --host "${LANGEXTRACT_API_HOST:-127.0.0.1}" --port "${LANGEXTRACT_API_PORT:-37141}"
For Ollama-backed models, set model_id to your tag (e.g. gemma2:2b), model_url to http://127.0.0.1:11434, and typically fence_output: false, use_schema_constraints: false per upstream README.
