list_catalog
List sources supership can procure across substrates: real-time crypto market data, news, on-chain analytics, prices, and more. Returns each source's URL, price, network, and description. Pass any of these URLs to procure.
LABSCO SUMMARY
Not needing the target chain's token is the thing that makes cross-chain procurement usable rather than theoretical.
The normal blocker for paying an x402 service on a chain you do not use is acquiring that chain's token first — a bridging exercise that costs more attention than the service is worth. Abstracting it removes the reason most cross-chain purchases never happen. The directory scanner sitting in the same server is an odd pairing on the face of it, and the connective logic is 'check before you ship' — reasonable, though it means attaching a payments server to get a secret scanner or the reverse. Worth being deliberate: procure spends money, and scan_directory reads your local filesystem.
What it is
An x402 procurement client with a security scanner attached: search the indexed service economy, fetch from a source on any supported chain, list what is procurable, and check a local directory before release.
What you get
- manifest searches the indexed x402 economy for the data or service you need.
- procure fetches from any x402 source across Base, Solana or Polygon without the caller holding that chain's token — the cross-chain settlement is handled rather than delegated.
- list_catalog enumerates what is procurable across substrates, including real-time market data among the categories.
- scan_directory checks a local directory for security problems including exposed secrets, framed as a pre-ship check.
Requirements
Procurement spends across x402, though the chain-token requirement is abstracted away.
Setup effort
One command — npx -y -p supership-scan supership-mcp
USE CASES
01
Finding a service that provides what you need
Search the indexed economy, or list the catalogue by category when you are not sure what exists.
02
Buying from a chain you do not hold tokens on
Fetch from the source directly — Base, Solana or Polygon — without acquiring that chain's token first.
03
Checking a repo before release
Scan the local directory for exposed secrets and other problems as a pre-ship gate.
4 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
manifest
Search the entire indexed x402 economy (52,000 services) for the data or service you need. Results are ranked by distinct payers -- real adoption -- not call counts, which wash trades inflate. Returns sources with price, network, payer count, and links to procure. The fastest way to find the right source.
procure
Fetch any x402 source across any chain (Base, Solana, Polygon) without holding a wallet on the seller's chain. supership fronts payment, delivers the goods, and returns a signed delivery receipt -- proof of what you got, settled on-chain. Find sources with the manifest tool. First runs are free.
scan_directory
Scan a local directory for security vulnerabilities before you ship: exposed secrets, auth holes, injection, config and Supabase misconfig. Code is analyzed by supership; the free tier returns score and grade only and stores no source.
