openquery 0.3.1

Query public data sources worldwide via scraping and APIs

OpenQuery

Query public data sources worldwide through a unified CLI and REST API.

OpenQuery provides a plugin-based framework for scraping government websites, public registries, and open data APIs. It handles the hard parts — browser automation, CAPTCHA solving, WAF bypass, caching, and rate limiting — so you can focus on the data.

Features

• Unified interface — one CLI and one API endpoint for all data sources
• Browser automation — Playwright-based scraping for JavaScript-heavy sites
• Multi-engine CAPTCHA solving — PaddleOCR (100%), EasyOCR+Tesseract voting (90%), with cloud and paid fallbacks
• LLM-powered knowledge CAPTCHAs — Ollama (local), HuggingFace, Anthropic, OpenAI fallback chain
• Audit & evidence — screenshots, network logs, and PDF evidence reports for compliance
• WAF bypass — browser-context API calls preserve session cookies
• Caching — in-memory, Redis, or SQLite backends with configurable TTL
• Rate limiting — per-source token-bucket to respect server limits
• REST API — FastAPI server with auto-generated OpenAPI docs
• Extensible — add new data sources by implementing a single class
• Country-organized — sources grouped by country code (co, us, etc.)

Built-in Sources

Installation

pip install openquery

Or with uv:

uv add openquery

System Dependencies

Playwright browsers are required for web scraping:

playwright install chromium

CAPTCHA Engines (pick one or more)

OpenQuery auto-detects installed OCR engines and builds an optimal solver chain:

Engine	Accuracy	Speed	Install
PaddleOCR (recommended)	100%	~130ms	pip install "openquery[paddleocr]"
EasyOCR + Tesseract (voting)	90%	~500ms	pip install "openquery[easyocr]" + brew install tesseract
Tesseract alone	80%	~390ms	brew install tesseract (included by default)

For knowledge-based CAPTCHAs (Procuraduria), you need at least one LLM backend:

Backend	Cost	Setup
Ollama (recommended)	Free	ollama pull llama3.2:1b
HuggingFace Inference	Free	Set HF_TOKEN env var
Anthropic	Paid	Set ANTHROPIC_API_KEY env var
OpenAI	Paid	Set OPENAI_API_KEY env var

Optional Extras

pip install "openquery[paddleocr]"   # PaddleOCR — best CAPTCHA accuracy (100%)
pip install "openquery[easyocr]"     # EasyOCR — good accuracy (85%), combines with Tesseract for 90%
pip install "openquery[huggingface]" # HuggingFace Inference API (OCR + QA)
pip install "openquery[serve]"       # FastAPI server (fastapi, uvicorn)
pip install "openquery[redis]"       # Redis cache backend
pip install "openquery[captcha]"     # 2captcha paid CAPTCHA solving (last resort)

Quick Start

CLI

# List available data sources
openquery sources

# Query Colombian traffic fines by cedula
openquery query co.simit --cedula 12345678

# Query Colombian vehicle registry by plate
openquery query co.runt --placa ABC123

# Query by VIN
openquery query co.runt --vin 5YJ3E1EA1PF000001

# Disciplinary records
openquery query co.procuraduria --cedula 12345678

# Criminal background
openquery query co.policia --cedula 12345678

# Health system enrollment
openquery query co.adres --cedula 12345678

# Pico y placa — is my plate restricted today?
openquery query co.pico_y_placa --placa ABC123

# Toll tariffs
openquery query co.peajes --custom peaje --extra '{"peaje": "ALVARADO"}'

# Fuel prices in Bogota
openquery query co.combustible --custom fuel --extra '{"municipio": "BOGOTA"}'

# EV charging stations in Medellin
openquery query co.estaciones_ev --custom ev --extra '{"ciudad": "Medellin"}'

# Road crash hotspots
openquery query co.siniestralidad --custom stats --extra '{"departamento": "CUNDINAMARCA"}'

# Vehicle fleet lookup by plate
openquery query co.vehiculos --placa ABC123

# Output raw JSON
openquery query co.simit --cedula 12345678 --json

# Generate audit evidence (screenshots + PDF report)
openquery query co.runt --placa ABC123 --audit --audit-dir ./evidence

REST API

# Start the API server
openquery serve

# Or with custom host/port
openquery serve --host 127.0.0.1 --port 3000

Then query via HTTP:

curl -X POST http://localhost:8000/api/v1/query \
  -H "Content-Type: application/json" \
  -d '{
    "source": "co.simit",
    "document_type": "cedula",
    "document_number": "12345678"
  }'

Response:

{
  "ok": true,
  "source": "co.simit",
  "queried_at": "2026-03-31T10:30:00Z",
  "cached": false,
  "latency_ms": 4523,
  "data": {
    "comparendos": 0,
    "multas": 0,
    "total_deuda": 0.0,
    "paz_y_salvo": true
  }
}

API Endpoints:

Method	Path	Description
POST	/api/v1/query	Query a data source
GET	/api/v1/sources	List available sources
GET	/api/v1/health	Health check and cache stats
GET	/docs	Interactive API documentation

Docker

docker compose up

This starts the API server with Redis caching on port 8000.

Adding a New Source

Create a new source by implementing the BaseSource class:

# src/openquery/sources/us/nhtsa.py
from pydantic import BaseModel
from openquery.sources import register
from openquery.sources.base import BaseSource, DocumentType, QueryInput, SourceMeta


class NhtsaResult(BaseModel):
    manufacturer: str = ""
    model: str = ""
    year: int = 0
    recalls: list[dict] = []


@register
class NhtsaSource(BaseSource):
    def meta(self) -> SourceMeta:
        return SourceMeta(
            name="us.nhtsa",
            display_name="NHTSA Vehicle Safety",
            description="US vehicle safety recalls and VIN decoding",
            country="US",
            url="https://vpic.nhtsa.dot.gov/api/",
            supported_inputs=[DocumentType.VIN],
            requires_captcha=False,
            requires_browser=False,
            rate_limit_rpm=30,
        )

    def query(self, input: QueryInput) -> NhtsaResult:
        import httpx
        resp = httpx.get(
            f"https://vpic.nhtsa.dot.gov/api/vehicles/decodevin/{input.document_number}",
            params={"format": "json"},
        )
        data = resp.json()
        # Parse and return NhtsaResult...

The @register decorator automatically makes the source available in the CLI, API, and source listing.
