    {
      "question": "Is there a free lead enrichment API here?",
      "answer": "The 15 listed services have positive per-call prices for their task endpoints. An uncharged miss or a free polling route does not make the paid lookup free; check the exact route and the provider's terms."
    },
    {
      "question": "What do 100,000 lead enrichment calls cost?",
      "answer": "At the median selected quote, 100,000 calls total $5,000.00 at $0.05 per call. This reference calculation assumes one call per lead and excludes verification calls, charged misses and refreshes."
    },
    {
      "question": "What is the difference between lead enrichment and lead generation?",
      "answer": "Enrichment completes a record you already hold, starting from an email, domain, profile URL or name. Generation, or discovery, finds new records that match criteria. This page compares enrichment and lists discovery routes as an adjacent output."
    },
    {
      "question": "Does a work-email lookup guarantee the address reaches the person?",
      "answer": "No. A lookup returns a candidate address under the provider's definition of a deliverable result. Mailbox existence, the person's current employment and their consent to contact are separate questions."
    },
    {
      "question": "Can a lead verification result replace KYC or KYB checks?",
      "answer": "A lead check confirms what a sales record holds, such as register status, tax number or mail domain. Customer due diligence for regulated onboarding needs its own documented process and evidence."
    },
    {
      "question": "How reliable is a prospect fit score?",
      "answer": "A fit score applies rules or a model to public evidence. Keep the evidence and the rule version with it, review a sample by hand and avoid treating the score as a probability of winning a deal."
    },
    {
      "question": "How often should enriched data be refreshed?",
      "answer": "Titles, employers and headcounts change. Store the observation date with each field and refresh the fields that drive routing or outreach before using them, rather than on a fixed schedule for the whole record."
    },
    {
      "question": "Does HTTP 402 establish a correct paid answer?",
      "answer": "It establishes a payment requirement for the request. A stored challenge, an observed payment and an accurate profile are different evidence; inspect the resource and request schema before paying."
