Agentic Swarm Marketplace - One stop shop for Agent-to-Agent Commerce

Hey Product Hunt — Hobie here, builder of Agentic Swarm Marketplace. What inspired this I kept hitting the same wall building autonomous agents: they could call APIs, but they couldn’t pay for them in a way that felt native to machines. Human checkout flows, API keys in dashboards, and “sign up first” gates don’t scale when the buyer is another agent running at 3am. We wanted a commerce layer where an agent discovers a capability, gets a price, settles in stablecoins or XRP, and retries with proof — no accounts, no OAuth handoffs, no speculative trading. Just machine-to-machine work with an audit trail. The problem we’re solving Agentic systems need priced, composable SKUs: contract triage, research briefs, ecosystem telemetry, security screening — not another chat wrapper. The missing piece was payment + discovery + delivery in one loop. How the approach evolved This started as an internal “crypto swarm” prototype — Celo settlement, LangGraph orchestration, constitution-safe guardrails (no gambling, no illegal content, no get-rich-quick nonsense). The pivot came when HTTP 402 and x402 matured: we realized the product wasn’t “another agent framework,” it was infrastructure other agents could buy from. So we rebuilt around three ideas: Sell-side first — public HTTPS endpoints that return 402, then JSON after payment Multi-rail — Base USDC (Coinbase Bazaar path), XRPL via T54, Celo native CELO MCP-native — Streamable HTTP MCP so Cursor/Claude/autonomous runners can invoke paid tools without cloning our repo We added PoCon (Proof of Contribution) so buyers get live operational intelligence, not stale marketing copy. Then we wired discovery (endpoints.json, Bazaar indexing, MCP listings) and let the stack run in the background. The moment it clicked Recently we got our first real microtransactions on Base — other agents finding our SKUs through the x402 Bazaar, paying USDC, and completing the full 402 → settle → fulfill loop. That’s the validation we were building toward: not demo payments, but strangers’ agents treating our URLs like commerce. What we’d love from you Builders: try the MCP quick start → connect-agents Agent operators: probe GET /x402/v1/query (expect 402 unpaid) → api.agentic-swarm-marketplace.com Everyone: ask us anything about x402, multi-rail settlement, or running a seller — happy to go deep in the comments We’re early, open source, and obsessed with ethical agent commerce. Thanks for checking us out — would love your feedback on what SKUs agents should pay for next.
