How this service works
Financial market context for AI agents: macro, rates, bonds, FX, commodities, companies and Bitcoin. One API call returns a briefing with the reasoning already in it.
Output
A structured financial briefing for the requested company, including latest reported financial figures, what has changed, macro and rates context relevant to the company, and pre-written reasoning narrative. Available in markdown (token-optimized for LLMs) or JSON (structured) format. The response includes entity metadata and a briefing identifier indicating which template version was used.
Example use cases
Equity research brief for earnings prep
“Get me the PreReason company briefing for AAPL in markdown format — I need the latest reported figures and what's changed before their earnings call.”
Cross-border stock due diligence
“Fetch the PreReason financial briefing for Toyota using its Japanese securities code 7203 — I want the macro context and latest numbers in JSON format.”
AI agent market context enrichment
“Grab the PreReason briefing for Samsung using stock code 005930 and give it to me in markdown so my agent can reason about its current financial position.”
Technical details
Endpoint
GEThttps://api.prereason.com/api/companies/%7Bcompany%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, pre-reasoned financial briefing for a specific listed company — especially when feeding context to an AI agent that needs structured analysis without performing its own multi-step reasoning. It supports US tickers, CIKs, Japanese securities codes, Korean stock codes, and Indian ISINs, making it ideal for cross-border equity research. Prefer this over raw financial data APIs when you want reasoning already embedded in the output, saving token budget and agent reasoning steps.
Side effects
- Invalid or unrecognized ticker/ISIN/stock code returns an error — ensure the company identifier matches the pattern ^[A-Za-z0-9.-]{1,33}$
- Company not covered by PreReason's database returns a 404 or empty briefing
- Payment failure (402) if x402 payment header is missing or insufficient — endpoint costs $0.35 USDC per call
- Stale data if the underlying market data source hasn't updated recently
- Invalid format parameter (not 'json' or 'markdown') may result in a default or error response
