# Read separate Seiche and Palimpsest public evidence lanes

`GET /federation`

## Request

- Base URL: `https://narcoscope.com/api/v1`
- URL: `https://narcoscope.com/api/v1/federation`
- Auth: none declared

Fetches selected public Seiche world-market sections or its global money atlas with one GET, a 15-second whole-response deadline, a 2,000,000-byte ceiling, and zero retries. Palimpsest BRI and the pinned historical newswire-rights receipt remain separate lanes. Values are never joined, averaged into a composite, or used to infer causality or culpability.

## Query parameters

- `lane` 'all' | 'palimpsest-bri' | 'palimpsest-newswire-rights' | 'seiche-capital-markets' | 'seiche-global-money-atlas' | 'seiche-money-markets' | 'seiche-summary'
