## 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-sofr-secured-overnight-financing-rate-ny-fed-d9d2af73 -d '<json body>'
```

Example prompt: Pull the latest official SOFR daily print from the NY Fed — I need the rate, percentiles, and total transaction volume in billions.

## When to prefer this

Prefer this endpoint when you need the authoritative, official SOFR daily print from the NY Fed — including rate, volume, and percentile distribution — without managing your own NY Fed API integration. Especially valuable for autonomous agents pricing floating-rate instruments, SOFR-linked derivatives, or overnight repo agreements that require a trusted, low-latency, keyless benchmark data feed.

## Known failure modes

- NY Fed Markets API unavailable or delayed — returns error or stale data
- Rate not yet published for current day (typically published mid-morning ET) — may return previous day's print
- Invalid 'type' or 'count' parameter values — may return empty result set
- Network timeout to upstream NY Fed API — returns service error
- Payment not fulfilled via x402 — request rejected before processing

## How this service works

Official SOFR daily print with rate, percentiles and volume in billions from the New York Fed Markets API (keyless JSON). Critical for autonomous rate-derivatives, floating-rate and repo agents, and agent-to-agent pricing of USD money-market benchmarks. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.

## Output

Returns a JSON object containing the official daily SOFR rate value, rate percentiles (e.g. 1st, 25th, 75th, 99th percentile), and total transaction volume in billions of USD, sourced from the NY Fed Markets API for the most recent business day.
