Supership Scan

The search engine and clearing house for the agent economy. Built by Crest Deployment Systems.

supership indexes the entire x402 economy -- 52,000 services -- so an AI agent can find the right data and fetch it with a receipt. Reading the menu is free. Fetching through supership returns the goods plus a signed delivery receipt: proof of what you got, from where, settled on-chain. That is the part going direct can never give you.

Tools

Tool	What it does
manifest	Search the whole x402 economy (52,000 services) for what you need. Ranked by distinct payers -- real adoption, not call counts. Free.
procure	Fetch any source. supership fronts payment across any chain, delivers the goods, and returns a signed receipt. No wallet needed on the seller's chain. First runs free.
list_catalog	Browse a curated catalog of procurable sources.
scan_directory	Scan a local directory for security issues before you ship.

Free menu, paid kitchen

• The menu is free. manifest shows the real market: every relevant source, free or paid, ranked by who actually paid for it. That ranking is the part you cannot compute yourself -- it takes the whole index and the payment history.
• The kitchen is the product. When you procure, supership crosses to the source (on whatever chain it lives), pays, takes delivery, and hands you the goods plus a signed delivery receipt -- an Ed25519 record of what was delivered (source, SHA-256 of the goods, settlement tx, timestamp), verifiable at /api/pubkey. That receipt is the provenance going direct cannot give you.

What supership does not do

• It does not sell the data. It indexes the market and delivers what you ask for, with a receipt.
• It does not hold your funds. The MCP server holds no keys and moves no money locally.
• It does not give investment advice.
