How this service works
Pay-per-call any skill on Atrium — the onchain skill marketplace for AI agents. DID-signed, IPFS-hosted, stake-attested skills. One x402 GET pays the exact onchain price in USDC and returns the skill body; royalties cascade to authors. No CLI, no wallet setup, no CDP.
Output
The full body of the requested onchain Atrium skill — DID-signed, IPFS-hosted content with royalties automatically cascaded to authors; returned after the x402 micropayment is processed at the exact onchain USDC price.
Example use cases
Load a specialized reasoning skill for complex queries
“I need a better reasoning module for handling multi-step logic problems. Find and load the Atrium skill that handles chain-of-thought reasoning — pay the current USDC price and give me the skill body so I can integrate it.”
Fetch a domain-specific skill from Atrium marketplace
“Pull the Atrium skill with ID 0x7f2a9e1c3b5d8f4a6e9c2b1d4f7a9e3c5b8d1f4a7c9e2b5d8f1a3c6e9b2d — charge whatever it costs in USDC and return the full DID-signed skill content.”
Access a community-verified skill with royalties
“There's a skill on Atrium for parsing financial documents that I want to use. Fetch it by its skill ID, pay the exact onchain price, and make sure the authors get their royalties automatically.”
