Scored across 4 tools
Each tool has a clearly distinct purpose: stats aggregation, receipt lookup, receipt publication, and cryptographic verification. The lookup versus verify boundary is explicit in the descriptions, with lookup retrieving records and verify assessing signatures/countersignatures.
All names use snake_case and a verb_noun pattern, which is predictable and readable. The three receipt-specific tools share the _delivery_receipt suffix, while log_stats is a minor deviation in object naming but still consistent in style.
Four tools is well-scoped for a server focused on publishing, finding, verifying, and summarizing delivery receipts. Each tool earns its place without redundancy or extreme thinness.
The core lifecycle is covered: publish a countersigned receipt, look it up, verify signatures, and view aggregate stats. Minor gaps exist, such as lookup by buyer key or broader listing/pagination, but these are not fatal for the stated purpose.
Available Tools
4 toolslog_statsPublic log statisticsARead-onlyInspect
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.
Inputs: no named parameters.
lookup_delivery_receiptLook up a countersigned receiptARead-onlyInspect
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.
Inputs: seller, receipt_id, file_sha256.
publish_delivery_receiptPublish a countersigned receiptAIdempotentInspect
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.
Inputs: receipt (required), buyer_link, seller_link.
verify_delivery_receiptVerify a delivery receiptARead-onlyInspect
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.
Inputs: receipt (required), file_sha256. Returns: state, valid, reasons
