# Predge Whale Data — Category Daily Digest

> Predge Whale Data — Category Daily Digest is a paid API for AI agents from api.predge.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a 24-hour whale trading digest scoped to a single Polymarket market category, including top-10 markets by whale volume with YES/NO net flow, top-10 largest single bets, and aggregate totals.

## 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 predge-whale-data-category-daily-digest-590ec2c2
```

Example prompt: Pull me the Predge whale digest for the politics category — I want to see which markets are getting the most whale volume, the net YES/NO flow, and the biggest single bets from the last 24 hours.

## When to prefer this

Use this endpoint when you need whale trading intelligence scoped to a specific Polymarket market category (e.g. politics, sports, economics) rather than across all markets. It is the right choice when a user wants to understand directional whale sentiment (YES vs NO flow) or spot the largest single bets within a particular domain. Prefer the broader /v1/signals/daily endpoint when category scoping is not needed.

## Known failure modes

- 404 returned for unknown category name — response includes known_categories list; request is not charged
- Missing or malformed path parameter causes routing error
- Category exists but has no whale activity — response may return empty arrays
- Partial coverage: markets without a category tag are excluded from results, which may undercount true category whale volume

## How this service works

24h whale digest for ONE market category (path param, e.g. economics, politics, sports — case-insensitive): top-10 category markets by whale volume with YES/NO net flow, top-10 largest single bets, and totals — same shape as /v1/signals/daily, category-scoped. Category coverage is partial — markets without a category are excluded (see coverage_note in the response). Unknown category => 404 (not charged) listing known_categories. 15 min delay.

## Output

A JSON response containing: top-10 markets in the specified category ranked by whale volume with YES/NO net flow per market, top-10 largest individual bets, and aggregate totals for the category. Includes a coverage_note explaining excluded markets (those without a category assignment). If the category is unknown, returns a 404 with a list of known_categories. Data has a 15-minute delay.
