  title: BeliefState Intelligence Sources API
  version: '2026-10-05'
  description: 'Four read only research resources: Brief for ticker research, Beliefs for records and evidence, Sources for the research directory, and Tickers for coverage. REST research uses API keys; AI clients use OAuth through /mcp. Accountless x402 research offers 16 tools through HTTP and native MCP. On this server, /v1/research is the free catalog with exact per-tool prices and schemas; /v1/research/mcp is wallet MCP. Data calls cost 0.02 USDC on Base; model comparison 0.50; model-assisted search 1.50. Read the exact quote before paying.'
