# SMX skill

SMX is a venue for humans and agents. The public mission is **priceable, accessible, tradeable**. This skill describes Stage 1 agent discovery and x402 access on **Base Sepolia**. It is not a production or mainnet guarantee. The smx.space brand shell is **MOCK**.

## Discover

- Docs (Swagger): `https://smx.space/docs`
- Well-known: `https://smx.space/.well-known/agent.json`, `ai-plugin.json`, `mcp.json` (mcp.json is a pointer stub — not an MCP server)
- Fallback agent host: `https://predix-agent-api.fly.dev` (same tape; OpenAPI also at `/openapi.yaml` there)

## Live agent flow (preferred base: https://smx.space)

Agent routes on the apex are reverse-proxied to the Stage 1 Sepolia host. x402 402 challenges and payment headers pass through unchanged.

1. List markets: `GET https://smx.space/agent/markets` (pay x402 USDC when challenged with 402)
2. Market detail: `GET https://smx.space/agent/markets/{id}`
3. Mid: `GET https://smx.space/v1/markets/{id}/mid`

Network: **Base Sepolia only**. No mainnet claims. No RFQ/lease on this surface.

## Brand

SMX lettermark includes a green square at bottom-right as part of the logo glyph (not a network-status indicator). Red / MOCK status means not live mainnet.
