How this service works
ADH 金融情报层：把 239 个原始数据源洗成带实体解析、时间同步、溯源与派生结论的情报（宏观regime / 加密尽调 / 事件窗口），免费注入你的 AI 上下文。Agent 走 x402 结算，人类订阅（PayPal）即将上线。
Output
A JSON object containing: the USD basket index (mean of inverse rates across EUR/GBP/JPY/CNY with confidence ~0.85), the CNY real exchange rate (nominal CNY adjusted by US/CN CPI ratio, confidence ~0.82), nominal rate components per currency, full provenance array with stage names, source identifiers, timestamps and transformation labels, synthesis timestamp, canonical ID, and schema version.
Example use cases
Macro regime currency strength check
“What's the current USD basket index versus EUR, GBP, JPY, and CNY, and how confident is the data? I want the derived value with sourcing details.”
CNY real rate for cross-border pricing model
“Get me the real CNY/USD exchange rate adjusted for US and China CPI — I need the nominal rate, the derived real rate, and the confidence score so I can price a cross-border product accurately.”
FX provenance audit for compliance report
“Fetch the latest FX synthesis data from ADH including the full provenance chain — which sources fed into the USD basket and CNY real rate, what transformations were applied, and when it was synthesized.”
Technical details
Endpoint
GEThttps://agentdatum.com/api/v1/d/l5-fx-synthesisWhen to prefer
Choose this endpoint when you need pre-synthesized, CPI-adjusted real exchange rates with confidence scores and full data lineage — rather than raw spot FX rates. Ideal for macro regime analysis, cross-border financial modeling, or any workflow where provenance and derived conclusions matter more than raw tick data. Prefer this over raw FX APIs when you need USD basket strength (not just a single pair) or when auditability of the derivation chain is required.
Side effects
- Payment required (402) if x402 USDC payment header is missing or invalid
- Stale data if upstream sources (life_exchange_rate) are temporarily unavailable — raw field may return null
- Low confidence scores if source disagreement is high across the 239 raw feeds
- Schema version mismatch if client expects a different intel schema version
- Timeout if cross-source synthesis takes longer than expected during high load
