Orders of Magnitude Scientific Literature API

Choose this endpoint when you need scientific literature data on a specific research topic and are comfortable with micropayment ($0.01 USDC via x402) access. It is suitable for AI agents that need to fetch academic or research content programmatically without managing subscriptions to traditional academic databases. Best for lightweight, on-demand lookups rather than bulk literature mining.

• Missing required 'topic' parameter returns a 400 or validation error
• Payment not authorized or insufficient USDC balance results in 402 Payment Required
• Obscure or misspelled topic may return empty or sparse results
• Service downtime on Railway hosting may return 503
• Rate limiting if too many requests are made in quick succession
