FAQ from Mycelia Signal Sovereign Oracle
How does pricing work?
Each endpoint has a fixed price in USDC: $0.01 for crypto, stablecoin, metals, FX, and gas oracles; $0.05 for indices, funding rates, and DeFi yield; $0.10 for economic indicators, commodities, marine, weather, and COT. Payment is handled via x402, a HTTP 402-based payment protocol on Base.
How can I verify signed data?
Every paid response includes an Ed25519 signature over a canonical attestation string (e.g., v1|PRICE|BTCUSD|73242.09|USD|2|...). Use the public key returned from the /health endpoint to verify. See the docs at myceliasignal.com/docs/verification/.
Is there a free tier?
Yes. Append /preview to any paid endpoint URL to receive unsigned sample data at no cost. The free DLC oracle endpoint also requires no payment.
What dependencies are needed for the MCP server?
The MCP server requires Python with the fastmcp and pynacl packages. No additional environment variables or external API keys are needed.
What integrations are supported?
The server is available as an MCP server (17 tools, Python + FastMCP), a LangChain package (langchain-mycelia-signal on PyPI), an OpenAPI specification, and Agent Discovery via agent.json and agent-card.json.
