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 synthora-fed-watch-us-reference-rate-funding-pulse-a526d351 -d '<json body>'
```

Example prompt: Pull today's SOFR, EFFR, TGCR, BGCR, and OBFR rates along with volumes and the SOFR-EFFR spread so I can see where overnight funding stress is sitting right now.

## When to prefer this

Use this endpoint when you need a single call that aggregates and cross-validates all five major US overnight reference rates from official NY Fed sources, particularly when monitoring funding market stress via the SOFR-EFFR spread or when feeding authoritative rate data into prediction markets or macro models. Prefer this over scraping NY Fed directly or using data vendor APIs when you want zero-key instant access with built-in cross-series validation and dispersion metrics.

## Known failure modes

- NY Fed source data not yet published for the day (rates typically published mid-morning ET)
- Malformed input string causes parsing error
- Network timeout reaching upstream NY Fed data
- x402 payment failure if USDC balance insufficient
- Rate data temporarily unavailable due to NY Fed maintenance
