Inputs

Field	Type	Required	What it is
`vat_number`	string	No	EU VAT number with country prefix (e.g. ATU14189108). Optional — used for VIES validation when the registry lookup does not return one (e.g. AT, SK); auto-derived from registry data where possible.
`gemi_number`	string	Yes	Greek GEMI registry number

How to call it

# Needs an API key. The whole check is charged once, at the listed price.
curl -X POST https://api.strale.io/v1/solutions/kyb-essentials-gr/execute \
  -H "Authorization: Bearer $STRALE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "inputs": {
      "gemi_number": "000237954001"
    },
    "max_price_cents": 150
  }'

# No account. The first request answers 402 with the price in USDC;
# an x402 client pays it from your wallet and repeats the request.
curl -i -X POST https://api.strale.io/x402/v2/solutions/kyb-essentials-gr \
  -H 'Content-Type: application/json' \
  -d '{
    "gemi_number": "000237954001"

Limitations

Data comes from the official registry's public API under its open-data terms (https://opendata.businessportal.gr/license/); results carry the registry as their source.
From step: Greek Company Data
Known GEMI status descriptions map to active, inactive, dissolved, bankrupt or liquidation; unrecognised descriptions are preserved and missing descriptions return unknown. These mappings are not independently confirmed against live GEMI responses.
From step: Greek Company Data
The GEMI Open Data API enforces a maximum of 8 requests per minute per API key. Requests exceeding this limit return HTTP 429.
From step: Greek Company Data
What to do instead: Space requests to stay within 8 per minute.
When AFM is missing the derived vat_number is null; vat-validate downstream steps will soft-fail for those entities.
From step: Greek Company Data
What to do instead: Provide the AFM as input directly when known, or use a separate VAT validation source.
GEMI includes branch records (is_branch=true) alongside main-entity records. Some KYB use cases want the parent only.
From step: Greek Company Data
What to do instead: Check the is_branch field before using the record as the principal counterparty.
VIES can be unavailable or throttle requests under unpublished per-member-state limits. Transient faults are retried, and cached results, including older fallback results, can be returned during outages.
From step: EU VAT Validation
What to do instead: Lookups within 48 hours can use cached results; if VIES is unavailable and no cached result exists, retry later.
Results can be cached for 48 hours, and national registry changes can take a further 24 hours to appear in VIES. Check the national tax authority directly for same-day registration or deregistration confirmation.
From step: EU VAT Validation
What to do instead: For real-time same-day verification, contact the national tax authority directly.
Swiss UID validation returns valid or invalid only, without a company name or address. This tool does not perform the separate enrichment lookup, whose public service is limited to 20 requests per minute.
From step: EU VAT Validation
What to do instead: For Swiss company name + address, call the swiss-company-data capability.
GB VAT numbers return a credentials-pending error when the HMRC connection is not configured.
From step: EU VAT Validation
What to do instead: Use vat-format-validate for GB format checks; it does not confirm VAT registration.
Sanctions lists updated daily from OFAC, EU, and UN sources — newly sanctioned entities may take up to 24 hours to appear
From step: Sanctions Check
What to do instead: For same-day compliance, subscribe to OFAC's RSS feed and cross-reference against today's additions
Name matching uses fuzzy logic — common names may produce false positives. Always verify flagged results
From step: Sanctions Check
What to do instead: Filter results by match confidence score and verify flagged entities against the primary sanctions list PDF
Covers entities with LEI registration via GLEIF — only ~2.5 million entities worldwide have LEIs, primarily financial institutions
From step: LEI Lookup
What to do instead: If no LEI is found, search by company name and jurisdiction; consider that smaller entities may not have an LEI
