# Seerium News Catalyst to Prediction-Market Links Feed

> Seerium News Catalyst to Prediction-Market Links Feed is a paid API for AI agents from api.seerium.xyz, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-15).

Returns ranked, confidence-scored links between breaking news catalysts and related prediction markets, with freshness, urgency, liquidity, and probability context for crypto tickers.

## 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 api-seerium-xyz-976bc072
```

Example prompt: Pull me the top 10 ranked news catalyst links to prediction markets for BTC, ETH, and SOL right now — only return ones with a confidence above 0.7, using Seerium's pulse catalysts feed.

## When to prefer this

Use this endpoint when you need to connect real-world news events to prediction market opportunities with confidence and urgency scoring — especially for crypto-focused catalysts (BTC, ETH, SOL) where you want ranked, actionable links rather than raw news or raw market data separately.

## Known failure modes

- Invalid ticker symbol returns empty results or 400 error
- minConfidence value outside 0–1 range triggers schema validation error
- Unknown source filter returns no results
- limit below minimum (1) returns error
- Payment not attached or insufficient USDC triggers 402 Payment Required
- No catalysts currently matching filters returns empty array

## How this service works

Crypto and prediction market intelligence through x402.

## Output
