Endpoint
POSThttps://marcroslencs.vercel.app/api/seriesWhen to prefer
Choose this endpoint when you need programmatic access to specific FRED or World Bank economic time-series data by series ID, especially when you also want AI-powered macro context via MiMo LLM. Prefer this over direct FRED API access when you want a pay-per-use model on Base via x402 without managing API keys, or when you want the MiMo LLM analysis layer on top of raw data.
Side effects
- Invalid or unknown series_id returns success: false with an error message
- Series ID exists but has no data returns an empty data object
- Payment failure on Base blockchain results in HTTP 402 before the endpoint is reached
- Network timeout on upstream FRED or World Bank data fetch
- Rate limiting if too many requests are made in a short window
