    {
      "question": "Is there a free B2B enrichment API in this comparison?",
      "answer": "The 12 listed services have positive per-call prices for their task endpoints. Inspect the particular request and provider terms for no-match, free-tier or failure handling; a recorded reference quote does not establish the price of a different request shape."
    },
    {
      "question": "How much do 100,000 B2B enrichment calls cost?",
      "answer": "Using the median selected endpoint, 100,000 calls total $2,650.00 at $0.0265 per call. This assumes the same request shape and paid unit. Retries, follow-up products and request-dependent pricing can change the effective total."
    },
    {
      "question": "Does an HTTP 402 check prove paid delivery?",
      "answer": "It demonstrates a payment requirement from the endpoint. It does not prove that a settled request returns accurate output. The listing reports monitoring and payment observations separately from the provider's advertised capabilities."
    },
    {
      "question": "Does email validation find a work email?",
      "answer": "Validation checks an address or domain already supplied. Discovery attempts to return an address for a matched person and company. DNS or syntax evidence does not establish mailbox existence, so preserve the exact kind of validation performed."
    },
    {
      "question": "What happens when a profile is not found?",
      "answer": "Read the endpoint's result states and billing description. A no-match, source failure, ambiguous identity and accepted background job are different outcomes. Keep those states separate when counting successfully enriched records and estimating effective cost."
    },
    {
      "question": "Are buying-intent signals verified facts?",
      "answer": "Treat them as provider interpretations unless the returned evidence establishes a specific observed event. Keep the source, date, confidence and stated method. Store a recommendation separately from a factual company or person field."
    },
    {
      "question": "How do I avoid merging the wrong company?",
      "answer": "Retain country, legal identifier and source domain, then inspect alternative matches. A trading name or shared website can relate to multiple legal entities. Do not replace a reviewed record solely because another response has a similar name."
    },
    {
      "question": "Does a company search return a batch?",
      "answer": "The paid unit depends on the endpoint. It may be one company, one person, a result page or a bounded batch. Confirm the documented limit before converting a per-call quote into an expected cost per usable profile."
    },
    {
      "question": "What should I store with enriched fields?",
      "answer": "Keep the original match key, returned identity, source URL, observation date and missing or uncertainty reason. Preserve manually reviewed values when a new match is ambiguous, and keep inferred scores separate from source-backed profile facts."
