BizVerify Python SDK

Official Python SDK for the BizVerify business entity verification API.

Installation

pip install bizverify

Quick Start

Authentication (Passwordless)

from bizverify import BizVerify

client = BizVerify()

# Request a verification code via email
client.auth.request_access("[e-mail]", accept_terms=True)

# Verify the code — client is automatically configured with the new API key
resp = client.auth.verify_access("[e-mail]", "123456", label="my-agent")
print(resp.api_key)  # Store this for future use

# Or initialize with an existing API key
client = BizVerify(api_key="bv_live_...")

Verify a Business Entity

client = BizVerify(api_key="bv_live_...")

# Synchronous verification (cached result)
result = client.verification.verify("Acme Inc", "us-fl")
print(result.status, result.data)

# Verify and wait for async job to complete
job = client.verification.verify_and_wait("Acme Inc", "us-fl")
print(job.status, job.result)

Search for Entities

# Single page
response = client.search.find("Acme", jurisdiction="us-fl")
for result in response.results:
    print(result.entity_name, result.confidence)

# Auto-paginate through all results
for result in client.search.find_all("Acme"):
    print(result.entity_name)

Response Metadata

Every API call populates last_response_meta with credit and rate limit info:

result = client.verification.verify("Acme Inc", "us-fl")
meta = client.last_response_meta
print(meta.credits_remaining)    # 85
print(meta.credits_charged)      # 15
print(meta.rate_limit_remaining)  # 59

Configuration & Jurisdictions

# Get full API configuration (no auth required)
config = client.config.get()
print(config.pricing)
print(config.jurisdictions)

# List supported jurisdictions
resp = client.config.jurisdictions()
for j in resp.jurisdictions:
    print(j.code, j.name, j.features)

Async Client

import asyncio
from bizverify import AsyncBizVerify

async def main():
    async with AsyncBizVerify(api_key="bv_live_...") as client:
        result = await client.verification.verify("Acme Inc", "us-fl")
        print(result.status)

        async for result in client.search.find_all("Acme"):
            print(result.entity_name)

asyncio.run(main())

Error Handling

from bizverify import BizVerify, NotFoundError, InsufficientCreditsError, RateLimitError

client = BizVerify(api_key="bv_live_...")

try:
    entity = client.entities.get("ent_nonexistent")
except NotFoundError as e:
    print(f"Not found: {e.message} (code={e.code})")
except InsufficientCreditsError:
    print("Need more credits")
except RateLimitError as e:
    print(f"Rate limited, retry after {e.retry_after}s")
