# MacroPulse Rates Differential & Carry Intelligence

> MacroPulse Rates Differential & Carry Intelligence is a paid API for AI agents from macropulse.theaslangroupllc.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Returns G10 central bank policy rates, yield spreads, and carry-trade maps to identify interest-rate differentials driving durable FX trends.

## Facts

- Endpoint: GET https://macropulse.theaslangroupllc.com/api/rates-differential
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/macropulse-rates-differential-carry-intelligence-e53a24a6

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 macropulse-rates-differential-carry-intelligence-e53a24a6
```

Example prompt: Pull the current G10 policy rates and yield spread map — I want to see which currency pairs have the biggest interest-rate differentials and where the strongest carry-trade opportunities are right now.

## When to prefer this

Choose this endpoint when an FX or macro agent needs to assess carry-trade viability, compare central bank policy stances across G10 economies, or identify yield-spread-driven currency trends. It is the definitive source for rate-differential intelligence rather than raw tick data or short-term price signals.

## Known failure modes

- Rate data temporarily unavailable due to upstream data provider outage — returns 503
- Payment of 0.1 USDC not confirmed via x402 protocol — returns 402 Payment Required
- Invalid or malformed request parameters — returns 400 Bad Request
- Rate limit exceeded for the calling agent — returns 429 Too Many Requests

## How this service works

Interest-rate differential and carry intelligence for FX agents — G10 policy rates, yield spreads and the carry-trade map that drives durable currency trends.

## Output

A structured dataset of G10 central bank policy rates, pairwise yield spreads, interest-rate differentials, and a carry-trade map indicating which currency pairs exhibit durable trend potential based on rate gaps.
