supership

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

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.
