# Massive x402 API – MACD Indicator

> Massive x402 API – MACD Indicator is a paid API for AI agents from agent.massive.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns Moving Average Convergence/Divergence (MACD) technical indicator data for a given US stock ticker, paid per-request via x402 micropayment.

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 massive-x402-api-macd-indicator-2aa68675
```

Example prompt: Pull the daily MACD indicator for AAPL using a 12-day short window, 26-day long window, and close prices — give me the last 20 data points in descending order.

## When to prefer this

Use this endpoint when you need MACD technical indicator data for US equities without requiring an account, API key, or subscription — ideal for pay-per-use agent workflows where you only need occasional or on-demand technical analysis. Prefer this over subscription-based data providers when cost-per-call economics are favorable and when you need flexible parameterization of windows, timespans, and price series types.

## Known failure modes

- Payment not settled — request returns 402 with payment terms if x402 payment is not provided or fails
- Invalid ticker symbol — may return an error or empty results if the ticker does not exist
- Out-of-range limit — values above 5000 are rejected
- Invalid timespan enum — only minute/hour/day/week/month/quarter/year are accepted
- Invalid timestamp format — must be YYYY-MM-DD or millisecond epoch
- No data available — some tickers or date ranges may have no aggregate data to compute MACD from

## How this service works

US stock market data, sold per request over x402. Every path here answers 402 with the payment terms in the PAYMENT-REQUIRED header, and answers with the data once the payment settles. No account, no API key, no subscription.

## Output

A JSON object containing an array of MACD result entries, each with a MACD value, signal line value, histogram value, and Unix millisecond timestamp. Also includes a URL to the underlying aggregate data used for the calculation and a next_url cursor for pagination.
