# LastLook Data — Rate Environment Bundle

> LastLook Data — Rate Environment Bundle is a paid API for AI agents from api.lastlookdata.com, paid per call via x402, $0.35/call, status unknown (last checked 2026-09-15).

Returns a snapshot of the current interest rate environment including FEDFUNDS, SOFR, DGS2, DGS5, DGS10, DGS30, yield curve spreads, and policy spread in a single call.

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 api-lastlookdata-com-0a7ce055
```

Example prompt: Give me a full snapshot of the current US rate environment — Fed funds, SOFR, the 2, 5, 10, and 30-year Treasury yields, yield curve spreads, and policy spread all at once.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-rate snapshot in a single API call rather than querying individual FRED series one by one. Ideal for macro analysis, LLM context injection, rate environment summaries, or any workflow that needs the full yield curve plus policy benchmarks simultaneously. Prefer over the individual FRED series endpoint when you need 6+ rate series at once and want to avoid multiple round-trips.

## Known failure modes

- FRED data source unavailable or delayed — stale or missing rate values
- Payment failure (x402) — call rejected if 0.35 USDC payment not provided
- Rate limiting — too many requests in a short window
- Network timeout — upstream FRED API slow to respond

## How this service works

## Output
