True Value Rankings API

Cryptocurrency research and scoring API. TVR's scoring model evaluates cryptocurrencies using 8 metrics rooted in Sound Value principles to produce TVR Scores (0-100). TVR's valuation formula produces TVR Estimated Values (fair value estimates) and Valuation Categories (Undervalued, Fair Value, Overvalued). All outputs are model-derived assessments. Data updated every 5 minutes. Free endpoints are served under /api. Two paid endpoints for agents, POST /premium/custom-ranking ($0.05) and POST /premium/portfolio-analysis ($0.08), are documented below as 402 then 200 and are paid in-band with x402 (USDC on Base) or MPP (USDC.e on Tempo, tempo charge, push mode); the live x402 offer is published at https://truevaluerankings.com/.well-known/x402.json. The same two products are MCP tools at https://truevaluerankings.com/mcp.
