Installation

pip install vynco

Or with uv:

uv add vynco

Quick Start

import vynco

client = vynco.Client("vc_live_your_api_key")

# List companies with filtering
result = client.companies.list(query="Novartis", canton="BS")
print(f"Found {result.data.total} companies")

# Get a single company
company = client.companies.get("CHE-105.805.080")
print(f"{company.data.name}: {company.data.legal_form}")

# Sanctions screening
screening = client.screening.screen(name="Suspicious Corp")
print(f"Risk: {screening.data.risk_level} ({screening.data.hit_count} hits)")

# AI risk score
risk = client.ai.risk_score(uid="CHE-105.805.080")
print(f"Risk score: {risk.data.overall_score}/100 ({risk.data.risk_level})")

# Credit balance
credits = client.credits.balance()
print(f"Credits remaining: {credits.data.balance}")

Async Usage

import vynco

async def main():
    async with vynco.AsyncClient("vc_live_your_api_key") as client:
        result = await client.companies.list(query="Novartis")
        print(result.data.items[0].name)

API Coverage

Response Metadata

Every response includes header metadata for credit tracking and rate limiting:

resp = client.companies.get("CHE-105.805.080")

print(f"Request ID: {resp.meta.request_id}")          # X-Request-Id
print(f"Credits used: {resp.meta.credits_used}")       # X-Credits-Used
print(f"Credits remaining: {resp.meta.credits_remaining}")  # X-Credits-Remaining
print(f"Rate limit: {resp.meta.rate_limit_limit}")     # X-Rate-Limit-Limit
print(f"Data source: {resp.meta.data_source}")         # X-Data-Source

Configuration

client = vynco.Client(
    api_key="vc_live_xxx",
    base_url="https://api.vynco.ch",  # default
    timeout=30.0,                      # seconds, default
    max_retries=2,                     # default, retries on 429/5xx
)

The API key can also be set via the VYNCO_API_KEY environment variable:

export VYNCO_API_KEY=vc_live_your_api_key

client = vynco.Client()  # reads from VYNCO_API_KEY

The client automatically retries on HTTP 429 (rate limited) and 5xx (server error) with exponential backoff (500ms x 2^attempt). It respects the Retry-After header when present.

Error Handling

All API errors are mapped to typed exceptions:

try:
    company = client.companies.get("CHE-000.000.000")
except vynco.AuthenticationError:
    print("Invalid API key")
except vynco.InsufficientCreditsError:
    print("Top up credits")
except vynco.ForbiddenError:
    print("Insufficient permissions")
except vynco.NotFoundError as e:
    print(f"Not found: {e.detail}")
except vynco.ValidationError as e:
    print(f"Bad request: {e.detail}")
except vynco.ConflictError:
    print("Resource conflict")
except vynco.RateLimitError:
    print("Rate limited, retry later")
except vynco.ServerError:
    print("Server error")
except vynco.VyncoError as e:
    print(f"Error ({e.status}): {e.detail}")
