  "faq": [
    {
      "question": "Is there a free VAT API in this comparison?",
      "answer": "The 16 listed services have positive per-call prices for their task endpoints. A free tier, a free evaluation country or an out-of-scope question refused without charge is a provider statement and does not make the paid route free. Check the terms for the exact request."
    },
    {
      "question": "How much do 100,000 VAT and tax calls cost?",
      "answer": "Using the median selected endpoint, 100,000 calls total $500.00 at $0.005 per call. That assumes one call per number or lookup; retries after a registry timeout and cached reads change the total."
    },
    {
      "question": "Is a VAT format check the same as a VIES check?",
      "answer": "No. A format or checksum check tells you the number could be valid. A VIES or national register check reports the registration status the registry returned. A provider that caches results can answer from an earlier check, so keep the time of the check with the result. The page lists them as separate data types."
    },
    {
      "question": "What happens if VIES is unavailable?",
      "answer": "It depends on the provider. Read each description: a route can report the registry as unavailable without a validity claim, serve a cached answer or fail. Store which kind of answer you received, with its date."
    },
    {
      "question": "Do VAT checks return the registered company name and address?",
      "answer": "Only where the endpoint documents it and the member state publishes it. Check the response fields before relying on a name match, and handle an empty name as unknown rather than a mismatch."
    },
    {
      "question": "Can I get the VAT rate of any country?",
      "answer": "Check the route and the description. Confirm that each country you need has a route, that reduced and zero rates are included where you need them, and what the route returns for a jurisdiction without a VAT."
    },
    {
      "question": "Does the comparison include US sales tax?",
      "answer": "As of October 26, 2026, 1 listed service documents US sales and use tax. The answer depends on the exact address, the taxability of the product and nexus, so send complete inputs and keep the rate breakdown with the order."
    },
    {
      "question": "Is a tax calculation from these APIs tax advice?",
      "answer": "No. A calculation applies the provider's rules to your inputs. Providers state their sources and limits; x402-list has not verified the results. Keep the inputs and outputs, and have a qualified person review the rules behind your filings."
    },
    {
      "question": "Does an HTTP 402 check prove a correct VAT answer?",
      "answer": "It shows that the endpoint asks for payment. It does not show that a settled request returns a correct registry or rate answer. The listing reports monitoring and payment observations separately from provider claims."
    },
    {
      "question": "Does latency show how long a VAT check takes?",
      "answer": "No. The latency column comes from unpaid monitoring checks. A paid registry check also waits for VIES or the national register, which can be slower or unavailable at times."
