🟢verify_delivery_receipt(receipt, file_sha256)
Proof of delivery check. Verifies a delivery receipt: the seller's signature over the deliverable hash (SHA-256) and, if present, the buyer's countersignature. Returns countersigned, seller-only or invalid, with reasons. Optionally compares a file's SHA-256 with the deliverable hash. Relevant to a delivery dispute or to checking a seller before payment. Free, no sign-up, no API key.

}🟢lookup_delivery_receipt(receipt_id, file_sha256, seller)
Finds countersigned receipts in the public log by receipt ID, deliverable hash (file SHA-256) or seller key. Shows a seller's published proof of delivery history. The log only holds receipts that a seller or buyer chose to publish, and a key is not a verified identity.

}🟢log_stats
Counts from the public log of countersigned receipts: receipts, distinct seller keys, distinct buyer keys and distinct seller-buyer pairs. Receipts the Wayreceipt team made for testing and removed entries are not counted.

}🟡publish_delivery_receipt(receipt, seller_link, buyer_link)
Publishes a countersigned receipt (already signed by both seller and buyer) to the public log, as lasting proof of delivery for a deliverable hash. Signing happens on your side with the free library; this server never holds keys. The server re-verifies the receipt and rejects seller-only or invalid ones. Optional seller_link and buyer_link pages are checked for proof that they belong to the signing key (match, mismatch or unreachable). Published receipts are public.
