# MacroLens Series Data Endpoint

> MacroLens Series Data Endpoint is a paid API for AI agents from marcroslencs.vercel.app, paid per call via x402, $0.35/call, status unknown (last checked 2026-09-14).

Fetches macro-economic time-series data for a given FRED or World Bank series ID, powered by AI analysis via MiMo LLM

## Facts

- Endpoint: POST https://marcroslencs.vercel.app/api/series

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability macrolens-series-data-endpoint-66077637 -d '<json body>'
```

Example prompt: Can you pull the FRED series data for US GDP (series ID GDPC1) so I can see the historical quarterly output numbers?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

AI-powered macro-economic analysis. FRED + World Bank data + MiMo LLM. 20 endpoints. x402 on Base.

## Output

Returns a JSON object with a success boolean and a data object containing the time-series observations, metadata, and values for the requested macro-economic series from FRED or World Bank sources.
