ProofOfFunds · ProofOfFunds Title / Escrow API

Embed source-verified buyer ProofOfFunds in your title or escrow workflow.

Title + escrow API for source-verified buyer proof-of-funds. Real estate offers, M&A bids, high-value transactions. $1,995/yr base + $1.95 per verify.

In plain English

What this API does for you.

If you're a real-estate broker, M&A advisor, escrow officer, or fund admin, this is the short answer for what Proof-of-Funds replaces in your day. Engineers, your bit is the endpoints below.

If you're a real-estate broker

Today you accept screenshots, faxed bank letters, or a 'trust me' from the buyer's lender. JIL's Proof-of-Funds returns a signed, timestamped CREB(TM) showing the buyer's institution confirmed sufficient liquid funds at the moment of the offer - with a coverage ratio (typically 1.10x or higher of offer price). The seller's listing agent can verify the signature on their end without calling you.

If you're an M&A advisor

Bidder PoF goes from 'letter of comfort on bank letterhead' to a portable cryptographic credential the seller's banker can verify. The 30-day reuse window means a serious bidder doesn't have to re-pull for every round. PoF tier covers institutional ranges; the per-verify fee is rounding-error against deal size.

If you're an escrow officer

Funds-good cuts down to one API call. Coverage-ratio + institution-name + pulled-at timestamp + signed CREB™ all land in your callback. If a transaction is later challenged (collusion, forged statement), the audit trail goes back to the buyer's bank, not to you.

If you're a fund admin or family office

Use Proof-of-Funds to clear LP capital calls in real time, not 5 business days after wires 'should have' hit. Same CREB(TM) format works for both side-letter LP confirmation and direct-investment offers.

If you're a buyer

You authorize a one-time read of your liquid balances at your bank or brokerage (Plaid Assets pipe; JIL never sees your login). You walk away with a portable credential good for 30 days that any seller, broker, or escrow can verify cryptographically. No more screenshotting your account or asking your banker for a letter on Friday afternoon.

What this is NOT

Not a credit check. Not a guarantee of funds at closing. Not a substitute for the underwriter's loan-commitment letter on financed deals. JIL proves the funds existed at a specific moment, signed by the bank's confirmation - not that they're irrevocably reserved for this transaction.

Capacity, not commitment

PoF CREBs reflect available balance at the moment of the institutional data pull. Balances may change. JIL does not guarantee that funds remain available, will be wired, will clear, or will be applied toward any specific transaction.

Counterparties relying on a PoF CREB™ should treat it as evidence of capacity at point in time, not as a payment commitment. JIL is not a bank, payment processor, fiduciary, or escrow agent.
