iturri

JavaScript client + CLI for the Iturri verified market-data API — historical market data for trading bots and AI agents where every bar carries a quality flag (verified · raw · reconciled · interpolated · disputed · outage) and every candle is traceable to a checksummed primary source.

• 124M+ quality-flagged OHLCV bars: 34 crypto symbols (1m/5m/15m/1h/1d since 2015) + 86 US stocks & ETFs (consolidated-tape EOD since 2016, as-traded and split-adjusted bases)

• Funding rates, open interest, taker order flow, curated events, market context (Fear & Greed, VIX, DXY…)

• Leakage-safe feature matrices, multi-timeframe aligned bundles, BSQ token sequences, training packs

• Agent-native: 11 MCP tools and x402 micropayments (USDC on Base) — no account, no API key

• Zero dependencies, ESM, Node ≥ 18

Install

Quickstart

import { catalog, bars, features, setToken } from "iturri";

await catalog();                    // free discovery — symbols, ranges, pricing

setToken("…");                      // membership token from iturri.ai/subscribe
                                    // (or export ITURRI_TOKEN)

const rows = await bars("BTC", "1h", { start: "2024-01-01", end: "2024-02-01" });
const clean = rows.filter(r => r.quality === "verified");   // the whole point

const feats = await features("SPY", "1d_split", { start: "2026-06-01" });

Without a token, priced endpoints return HTTP 402 with an x402 quote — payment-capable agents settle per call ($0.001 per 1,000 candles) with no human in the loop.

CLI

npx iturri catalog
npx iturri bars BTC 1h --start 2024-01-01 --end 2024-02-01
npx iturri features SPY 1d_split --start 2026-06-01
npx iturri bundle crypto            # signed training-pack URLs

Full surface

catalog · bars · features · funding · openInterest · orderflow · context · events · regime · validate · bundle — mirroring the 11 MCP tools at https://iturri.ai/mcp.

validate(symbol, tf, {start, end}) returns a data-quality report (coverage, gaps, flag distribution) so you can audit a range before backtesting on it.
