Full access (paid)

Get an API key instantly with a card at https://api.gocreativeai.com/credits/buy (or pay-per-call in USDC via x402 — no key at all):

c = Client(api_key="gck_...")

c.screen("Some Person")        # full sanctions & PEP coverage

KYB identity / tax-ID validation (paid)

Reject malformed business identifiers before an expensive registry call — deterministic check-digit + reference-data validators for onboarding and vendor due diligence:

c = Client(api_key="gck_...")

c.verify_lei("529900T8BM49AURSDO55")
# {'verdict': 'VALID_ACTIVE', 'checksum_valid': True,
#  'entity': {'legal_name': 'Ubisecure Oy', 'legal_jurisdiction': 'FI', 'entity_status': 'ACTIVE', ...},
#  'registration': {'lei_status': 'ISSUED', ...}}   # ← live GLEIF Level-1 record

c.verify_gstin("27AAPFU0939F1ZV")   # India GSTIN — mod-36 checksum + state + embedded PAN
c.verify_pan("AAPFU0939F")          # India PAN — structure + holder type
c.verify_gtin("4006381333931")      # GTIN/UPC/EAN — GS1 mod-10 check digit + region
c.verify_uk_vat("GB434031494")      # UK VAT — HMRC modulus-97 (9755)

# Or use the dispatcher for any validator:
c.verify("lei", "5493001KJTIIGC8Y1R12")
c.verify("latam-taxid", "GODE561231GR8", country="MX")

Reference-data / identifier validators (paid)

Why this vs the incumbents

Same OpenSanctions data the serious vendors use, but keyless and pay-per-call — a fraction of the cost of Dataspike, ComplyAdvantage, or enterprise contracts, and it adds crypto-wallet OFAC screening most don't. See the comparisons: vs Dataspike · vs sanctions.io · vs ComplyAdvantage.
