avacache

Public, anonymous HTTPS archive of the Avalanche C-Chain as daily Parquet files.

Every UTC day of the chain is served as three Parquet files — blocks, txs, and events — behind parquet.avacache.com. Fetch a full day, a range, or use HTTP range reads for column pushdown straight from the bucket.

Install

pip install avacache

from avacache import Client
c = Client()
t = c.load_day("2026-04-18", "txs")
print(t.num_rows, t.schema.names)

npm install avacache

import { Client } from 'avacache';
const c = new Client();
const rows = await c.loadDay('2026-04-18', 'txs');
console.log(rows.length);
