Summary

Adding Carbon & Cashmere to the x402 ecosystem as a Services/Endpoints project.

Category: Services/Endpoints

What we built

Production crypto trading intelligence API with 49 x402-paid endpoints and 22 MCP tools, powered by own blockchain nodes:

  • Bitcoin Core (pruned): 20 whitelisted RPC methods via x402 pay-per-call
  • Ethereum Nimbus: Beacon chain analytics
  • Kaspa (Rusty Kaspa): Network/hashrate monitoring
  • Bittensor Subtensor: Subnet activity tracking

Intelligence layer: ML ensemble predictions, funding rate analysis (70-85% backtest WR), market regime detection, mempool analytics, exchange flow tracking.

x402 Integration

  • 4-chain USDC payments: Base, Solana, Algorand, Stellar
  • Facilitators: Coinbase CDP (Base/Solana), GoPlausible (Algorand), OZ (Stellar)
  • Pricing: $0.002 - $0.25 per call
  • MCP Server: Streamable HTTP + SSE, 22 tools (7 free, 15 paid)

49 endpoints — that's a serious x402 footprint. Filed #140 for x402-saas (hosted onboarding proxy + multi-tenant facilitator). If you ever want to test a zero-SDK proxy in front of Carbon & Cashmere's surface, free first-tenant for ecosystem builders. No pressure — happy to also just trade notes on edge-cases you've hit running a high-cardinality x402 catalog.
