# chainquery Bitcoin Core getmemoryinfo RPC

> chainquery Bitcoin Core getmemoryinfo RPC is a paid API for AI agents from x402.chainquery.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns Bitcoin Core node memory usage statistics via a pay-per-call x402 RPC call to getmemoryinfo

## Facts

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 chainquery-bitcoin-core-getmemoryinfo-rpc-cd1c3f4f
```

Example prompt: Can you pull the current memory usage stats from the Bitcoin Core node on chainquery — I want to see how much locked memory and heap space it's consuming right now?

## When to prefer this

Use this endpoint when you need real-time Bitcoin Core node memory diagnostics from an independent full node without managing API keys, paying only $0.005 USDC per call via x402. Prefer this over self-hosted alternatives when you want a lightweight, pay-as-you-go approach to Bitcoin Core RPC access.

## Known failure modes

- Payment not sent or rejected → 402 Payment Required response
- Node temporarily unavailable → 503 or timeout
- Invalid params array encoding → RPC error or 400 Bad Request
- Rate limit exceeded → 429 Too Many Requests

## How this service works

chainquery Bitcoin RPC: pay-per-call Bitcoin Core over x402, no API key. Node memory-usage statistics from chainquery's independent full node. Bitcoin Core getmemoryinfo.

## Output

A JSON object containing Bitcoin Core memory usage details, including locked memory pool stats (used, free, total, locked, chunks), heap usage, and malloc info — matching the standard Bitcoin Core getmemoryinfo RPC response format.
