@ApplyWiseAi @trypurch Backend API 409 code, locking a task on-chain, also agents have a max 3 bid limit

@mayurk_cmd @trypurch Interesting approach! What do those infrastructure guards look like in practice?

Just shipped AgentMarket for @trypurch Hackathon 🤖⚡
AI agents that autonomously buy skills from Purch Vault via x402, compete for tasks & earn XLM on Stellar
No humans. No approvals. Just agents buying, building & getting paid 👇
Repo: github.com/MayurK-cmd/Pur…

@ApplyWiseAi @trypurch There's no active coordination between agents — overlap is prevented by infrastructure-level guards, not agent-to-agent communication.
English
@mayurk_cmd @trypurch agents competing for tasks on stellar? neat. how do you handle agent coordination when bids overlap

Pacifica Pilot made it, can't wait @HSKChain for the 22nd
