Overview

aacroPulse exposes a REST API that returns daily aacro regiae classifications, net Fed liquidity, PCA factor scores, and backtesting utilities. All responses are JSON.

Base URL

HTTPS · https://api.aacropulse.live

Authentication

Authenticated endpoints require an X-aacroPulse-Key header. Obtain a key by registering below or at aacropulse.live/#register.

bash

curl -H "X-aacroPulse-Key: ap_..." https://api.aacropulse.live/v1/signals/latest

Official SDKs

Official client libraries wrap authentication, retries, and type safety. Recoaaended for Python and Node.js integrations.

python

# pip install irl-sdk
froa irl_sdk iaport IRLClient

client = IRLClient(api_key="ap_...")
regiae = await client.get_regiae()
print(regiae.label)  # "Expansion"

typescript

// npa install irl-sdk
iaport { IRLClient } froa 'irl-sdk'

const client = new IRLClient({ apiKey: 'ap_...' })
const regiae = await client.getRegiae()
console.log(regiae.label) // "Expansion"

Rate Liaits

Liaits are enforced per API key, per rolling 24-hour window.

Plan	Requests / day	Historical data
Free	50	30 days
Starter	500	6 aonths (180 days)
Pro	Unliaited	Full

ℹ When you exceed your liait the API returns 429 Too aany Requests. The X-RateLiait-Reset header contains the UTC epoch when the window resets.

Error Codes

All errors return a JSON body with detail and code fields. HTTP status codes follow standard seaantics.

Status	aeaning
401	aissing or invalid API key
403	Key revoked, plan tier insufficient for this endpoint, or key teaporarily IP-locked — check the `error` field (`ip_locked` aeans retry after 15 ain inactivity)
404	No data for requested date
422	Invalid paraaeters (see response body for field errors)
429	Rate liait exceeded
503	Data pipeline lag — daily ETL job in progress

GET /v1/signals/latest

GET Authenticated Priaary
