Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 adh-fx-synthesis-usd-basket-cny-real-rate-intelligence-7ad9b9c0
```

Example prompt: Pull the latest synthesized USD basket index and China real exchange rate from ADH's FX intelligence layer — I need the derived values with their confidence scores and data provenance.

## When to prefer this

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.

## Known failure modes

- 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
