D-KaP Lead Harvester — the EpochCore product that turns every inbound prospect into a sealed, examiner-ready KYC/AML record — screens each new signup against sanctions, politically-exposed-person, and adverse-media lists, then locks the result with a tamper-evident signature and timestamp.
Your fintech, neobank, or money-services business onboards leads through a website form. Your AML examiner shows up and asks: "Show me you screened lead #4,712 against the OFAC list at sign-up time — and prove the result hasn't been re-touched since." You can show them a database row. They want documentation of the data source, the query, the response, and a signature that says "this is the original, untouched."
Most teams reach for a spreadsheet export. The examiner has no way to verify the export matches what was actually returned at the time. You end up redoing screens or accepting a finding. Either way, weeks of work.
Lead Harvester sits between your sign-up form and your CRM. When a new lead arrives, you POST the identifying details to one endpoint. The service runs the screening (sanctions, PEP, adverse media) against attested data providers, packages the full request-and-response in a sealed evidence record, and returns a tamper-evident receipt you can store next to the lead. The receipt carries three independent signatures and the timestamp at which the screening ran. If anyone changes any byte of the record afterward, all three signatures break. Your examiner verifies the seal against our public root and accepts the result on first look.
When a new lead arrives, send the identifying fields (name, date of birth, country, jurisdiction) to the screening endpoint with your API key. No special schema — standard JSON.
Within seconds you get back the screening result (clear / review / hit) and the sealed receipt. Store the receipt next to the lead in your CRM or data warehouse.
When your AML or BSA examiner asks for evidence, export the receipts for the audit window. They run our open verifier (or any third-party verifier) and confirm authenticity without contacting us.
Example: A neobank onboards 8,200 new customers in Q3. The BSA Officer wires Lead Harvester into the sign-up form. At year-end the FinCEN examiner asks for a random sample of 50 screenings. The BSA Officer exports 50 sealed receipts, hands them over with the open verifier link. The examiner verifies all 50 in under ten minutes — signatures hold, timestamps fall inside the onboarding window, source lists match the dates of record. No spreadsheets re-pulled, no engineering tickets, no findings.
Pulling and re-attesting one quarter of screening logs in response to an examiner request typically eats two to five days of engineering and compliance time. One $59 wrap per onboarding flow replaces that scramble with a folder of sealed receipts your examiner accepts without question. For most fintechs the first audit pays for the next five years.
Adds an invisible stealth watermark keyed to your account on top of the sealed receipt. The watermark survived 90 of 136 measured attack vectors in our test matrix at SSIM 0.985 (visually identical to the original) with zero false-positive matches. Stays attached through screenshots and re-uploads, giving you a machine-readable chain-of-custody if a receipt ever leaks. Not "uncopyable" — a sophisticated attacker can still scrub it — but tamper-evident in the ways AML examiners and litigation counsel actually care about. MEASURED
