Two paid tiers sit on top, both billed per call over x402 micropayments (USDC on Base — no account, no API key):
POST /v1/private/topup-crypto — free quote, no x402, no key; we detect
the coin payment with the same view-key scanner the product sells). Drive
it from the API, the MCP tools, or the
WalletConnect control panel.| What | URL | Auth |
|---|---|---|
| REST API | https://api.seneschal.space | None |
| MCP (Streamable HTTP) | https://mcp.seneschal.space | None |
| Control panel (Private Watch) | https://panel.seneschal.space | Wallet |
| Docs | https://docs.seneschal.space | - |
| Live stats dashboard | https://stats.seneschal.space | - |
Rate limit: 120 requests/min/IP at the REST host. The MCP host pipelines requests over a single transport so the same limit applies per session.
curl 'https://api.seneschal.space/v1/liquidations/atrisk?max_hf=1.05&min_debt_usd=1000'
