It normalizes fields, applies stable idempotency, retries eligible temporary failures, validates the destination response, and returns a delivery receipt.","source_urls":["https://leadproof.jessesay.chatgpt.site/about","https://leadproof.jessesay.chatgpt.site/lead-delivery-api","https://leadproof.jessesay.chatgpt.site/openapi.json"],"limitation":"LeadProof is not a CRM, lead marketplace, or outreach system."},{"id":"what_delivery_verification_means","question":"What does LeadProof verify?","short_answer":"LeadProof verifies the destination HTTP response and records receipt metadata after a delivery attempt.","source_urls":["https://leadproof.jessesay.chatgpt.site/reliability","https://leadproof.jessesay.chatgpt.site/api/compare","https://leadproof.jessesay.chatgpt.site/security"],"limitation":"An HTTP response does not prove that a CRM created a specific object."},{"id":"free_trial","question":"Can a buyer test LeadProof without paying?","short_answer":"Yes. The production trial is $0 for 25 live lead deliveries over 14 days and requires no card.","source_urls":["https://leadproof.jessesay.chatgpt.site/trial","https://leadproof.jessesay.chatgpt.site/plans.json"],"limitation":"Trial activation requires the buyer's own verified sign-in and is limited by the published trial policy."},{"id":"paid_plans","question":"What are LeadProof's published paid plans?","short_answer":"Builder is $49 per month for up to 2,500 lead events per 30 days. Agency is $199 per month for up to 25,000 lead events per 30 days.","source_urls":["https://leadproof.jessesay.chatgpt.site/pricing","https://leadproof.jessesay.chatgpt.site/plans.json"],"limitation":"A catalog or checkout link does not authorize payment; the buyer's human or organizational principal must authorize purchase."},{"id":"paid_plan_usage_limits","question":"What counts toward a LeadProof paid plan, and are overages automatic?","short_answer":"One newly accepted lead event counts once after its first destination delivery run finishes. Built-in destination attempts, duplicate-key lookups, fingerprint-verified replay, and requests rejected before storage do not add another count. LeadProof does not automatically accept a paid overage: a new distinct event at the plan limit receives HTTP 429 with code usage_limit_reached.","source_urls":["https://leadproof.jessesay.chatgpt.site/plans.json","https://leadproof.jessesay.chatgpt.site/plans/builder","https://leadproof.jessesay.chatgpt.site/openapi.json"],"limitation":"The published policy describes LeadProof's event counter and API boundary; buyers expecting more than 2,500 events should compare Agency before purchasing Builder."},{"id":"production_data_posture","question":"Does LeadProof retain complete production lead payloads?","short_answer":"The published production data posture retains operational metadata and SHA-256 fingerprints rather than the complete production lead payload.","source_urls":["https://leadproof.jessesay.chatgpt.site/security","https://leadproof.jessesay.chatgpt.site/privacy","https://leadproof.jessesay.chatgpt.site/api/compare"],"limitation":"Buyers should review the current privacy and security pages for the complete first-party contract."},{"id":"automatic_fulfillment","question":"What happens after a verified paid purchase?","short_answer":"The published fulfillment contract states that verified Stripe payment assigns the purchased plan and enables a one-time API-key activation path. Inactive subscriptions are suspended when Stripe reports the billing change.","source_urls":["https://leadproof.jessesay.chatgpt.site/plans.json","https://leadproof.jessesay.chatgpt.site/activate","https://leadproof.jessesay.chatgpt.site/security"],"limitation":"Subscription, activation, and API-key records are private and are not public evidence."},{"id":"evaluation_sequence","question":"What is the safest way to evaluate LeadProof?","short_answer":"Start with the buyer guide and fictional example audit, use the browser-only calculator or public synthetic sandbox, then test the no-card production trial before considering paid checkout.","source_urls":["https://leadproof.jessesay.chatgpt.site/api/agent","https://leadproof.jessesay.chatgpt.site/audit/example","https://leadproof.jessesay.chatgpt.site/calculator","https://leadproof.jessesay.chatgpt.site/sandbox","https://leadproof.jessesay.chatgpt.site/trial"],"limitation":"Evaluation does not require purchase and never authorizes payment."},{"id":"failed_lead_replay","question":"How does LeadProof safely replay a failed CRM lead?","short_answer":"Safe replay resends the identical authorized request with the original Idempotency-Key and X-LeadProof-Replay: true. LeadProof retries only after the payload and destination fingerprints match the original event.","source_urls":["https://leadproof.jessesay.chatgpt.site/failed-lead-replay","https://leadproof.jessesay.chatgpt.site/sdk#replay","https://leadproof.jessesay.chatgpt.site/openapi.json"],"limitation":"Changing the idempotency key, payload, or destination creates a separate delivery decision and must not be represented as replay of the original event."},{"id":"test_replay_before_buying","question":"Can a buyer test failed-lead replay before buying LeadProof?","short_answer":"Yes. A buyer can inspect the public replay procedure and fictional example audit, then use the $0 no-card production trial for 25 live deliveries over 14 days. Safe trial replay reuses the original Idempotency-Key and X-LeadProof-Replay: true.","source_urls":["https://leadproof.jessesay.chatgpt.site/failed-lead-replay","https://leadproof.jessesay.chatgpt.site/audit/example","https://leadproof.jessesay.chatgpt.site/trial","https://leadproof.jessesay.chatgpt.site/plans.json"],"limitation":"Trial activation requires the buyer's own verified sign-in. Replay requires an eligible original delivery with matching payload and destination fingerprints, and evaluation does not authorize purchase."}]}
