USGS minerals fundies
Annual USGS Mineral Commodity Summaries for metals and minerals — preferred over monthly Pink Sheet indicative prints for fundies context.
Why not Pink Sheet for metals fundies?
Pink Sheet metals can be monthly indicative with licensing nuance. USGS MCS is the cleaner annual fundies document path for agent reasoning.
Is USGS real-time?
No — Mineral Commodity Summaries are annual. freshness_class reflects that cadence.
How do agents discover the path?
Listed in /llms.txt, /openapi.json, and /.well-known/x402.json; MCP get_fundamentals covers USGS.
