How this service works
Ready-made intelligence reports for AI agents: company, country, daily market, EU tenders, domain due diligence, location, literature review, food product, package risk and document translation briefs. Each brief fuses several live data sources and is written by Llama 3.3 70B under strict no-fabrication rules (English or Arabic). USDC on Base mainnet over x402. No API key, no account.
Output
A structured JSON report containing today's date-stamped market subject line, BTC price in USD, BTC 24-hour percentage change, Fear & Greed index with label, EUR/USD exchange rate, and an overall confidence rating — all synthesized from live data sources by an LLM with anti-fabrication constraints.
Example use cases
Morning crypto portfolio check
“Give me this morning's market brief — I want BTC's price and 24h change, the current Fear and Greed index, and the EUR/USD rate so I can decide whether to rebalance today.”
Arabic-language market update
“Pull today's daily market intelligence report in Arabic — I need the key crypto and forex numbers for a briefing I'm preparing.”
Automated daily market digest
“Every morning, fetch today's market brief and tell me if Fear and Greed is in Fear territory and where BTC opened, so I can adjust my day-trading plan.”
Technical details
Endpoint
GEThttps://briefs402.worlddata402.workers.dev/v1/brief/market?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pre-packaged daily market snapshot combining crypto (BTC) and forex (EUR/USD) data with sentiment indicators, without needing to integrate multiple separate financial data APIs. Ideal for agents that need a single-call morning briefing with no API key setup, paying per-use via USDC on Base. Less suited if you need equity markets, real-time tick data, or historical time series.
Side effects
- Payment failure if USDC balance on Base mainnet is insufficient or x402 handshake fails
- Data freshness lag if underlying live sources are delayed or unavailable
- Language enum mismatch if an unsupported language code is passed (only 'en' and 'ar' are valid)
- Rate or timeout errors from the Cloudflare Workers runtime under heavy load
