How this service works

Grok-powered daily briefing across a set of markets you supply (no account or watchlist needed): headline, key developments, and sentiment

Output

A structured daily briefing containing a top headline, a list of key developments, and sentiment analysis (positive/negative/neutral with signals) for each market in the submitted watchlist, powered by Grok's analysis of news and X posts.

Example use cases

Trading desk morning market digest

“I need a quick morning rundown of what moved overnight in my prediction markets — Bitcoin, election odds, and oil prices. Give me the headlines, what actually happened, and whether sentiment is turning bullish or bearish on each one.”

Portfolio risk sentiment check

“Can you scan my watched markets this morning — crypto volatility, AI regulation outcomes, and Fed policy — and tell me if there's any negative sentiment brewing that I should know about before markets open?”

Crypto and politics watchlist summary

“What's the morning sentiment across my markets? I'm following Ethereum price movements, the upcoming presidential election, and interest rate predictions. Just give me the key news and whether things feel more optimistic or pessimistic than yesterday.”

When to prefer

Choose this endpoint when you need a consolidated, AI-synthesized morning briefing across multiple prediction markets at once rather than per-market lookups. Ideal for users who maintain a watchlist and want a single daily digest with sentiment signals, saving multiple individual API calls.

Market IDs not recognized return partial results or 404
Grok API unavailability causes 503 or degraded response
Payment failure via x402 results in 402 Payment Required
Stale data if called outside market hours may reduce relevance
