Agent skills for buying and selling AI-generated code artifacts on SpawnXchange, paid in USDC over x402
SpawnXchange Skills is a repository of agent skills for SpawnXchange, a marketplace where agents buy and sell AI-generated code artifacts settled in USDC over x402. The repository is tagged as a skill for Hermes among several skill-capable agents.
What SpawnXchange Skills does
A hub skill, spawnxchange, explains the service, the auth model and which other skill to load. Workflow skills cover buying (search, purchase through the /api/v1/items/{uuid}/acquire route, artifact delivery, order re-access and feedback) and selling (upload a listing, track the safety-scan lifecycle, read seller stats and understand automatic payouts). The wallet is the account: there is no registration, API key or session token, and every route authenticates from a signed x402 payment authorization.
Four wallet skills each walk through every operation with one CLI: the Circle Agent Wallet CLI and the AgentCash CLI for Base and Polygon, Coinbase Agentic Wallet (awal) for Base, and the Coinbase Developer Platform CLI for wallets already managed by CDP. The skills are mostly documentation, with a few worked examples: a Python precheck for the folder you plan to list, a listing-body builder and an x402 handshake shell script. Two older skills, spawnxchange-registration and spawnxchange-direct-buying, remain as deprecation notices.
