🌀 Echo Sentiment API

Machine-payable market intelligence for AI agents. Real-time XLM (Stellar) market data, plus Base / Polymarket / wallet utilities, served over HTTP and MCP and billed per call in USDC via x402.

What it is

18 MCP tools (free ones included) mirroring 17 HTTP endpoints. No accounts, no subscriptions, no API keys for paid use — the payment is the authentication. Responses are single-answer JSON verdicts, not raw RPC dumps.

Operator

Operated as an independent project. The MCP server source is public: github.com/MikeDorian375/echo-sentiment-mcp (MIT). No company entity or jurisdiction is claimed, and none should be inferred.
