Finance Toolkit

Tiingo answers to one API key for 80,000-plus equities, FX, crypto and two decades of fundamentals, plus a corpus of roughly 70 million news articles for anyone training a sentiment model on top. Grab a key at tiingo.com and the free tier already covers 30-plus years of daily history; ask for fundamentals or real-time IEX quotes and you move to a paid add-on. It's the paid fallback quants reach for once scraped data stops being reliable enough to trust. Pricing: free tier caps at 1,000 requests/day and 500 unique symbols/month; the Power plan starts at $30/month for 100,000 requests/day and the full 110,000-symbol universe.

EODHD covers 150,000-plus tickers across 60 exchanges with fundamentals, options and news behind one REST API, but the real update this year is its MCP server: a March 2026 rewrite took it from 75 to 88 tools, added OAuth 2.0 so an agent no longer carries a raw key in the URL, and added sanctions-screening and congressional-trades endpoints. Install the MCP server from GitHub, or just hit the REST API with a free key. Pricing: free tier gives 20 calls/day with 15-minute-delayed quotes and a year of history; the entry paid plan, Historian, runs €19.99/month for 100,000 calls/day and 30-plus years back.

Twelve Data hands out real-time US equities, forex and crypto quotes plus technical indicators on a free key with no card required, which is more than most data APIs give away before billing starts. pip install twelvedata, or call the REST endpoints straight from any language with an HTTP client. It's become a common first stop for side projects that need live US market data without a Databento-sized invoice. Pricing: free Basic plan caps at 800 calls/day; the Grow plan starts at $29/month for 55 calls/minute with no daily ceiling.

Qlib handles the whole quant-research pipeline under one Microsoft-maintained roof: data handling, factor mining, model training (including reinforcement learning) and backtesting. pip install pyqlib gets the package, and with roughly 50,000 GitHub stars and commits as recent as October 22, 2026, it's what most ML-leaning quant researchers reach for first. This year it absorbed RD-Agent, Microsoft's LLM-driven system for automating factor and model search, described in a paper published in May. Pricing: free and open source, MIT.

vectorbt runs thousands of parameter combinations of a strategy at once by vectorizing the whole backtest over pandas and NumPy instead of looping bar by bar. pip install -U vectorbt gets the library, and a from-scratch Rust execution engine replaced its old Numba-JIT hot paths in v1.0.0, released April 2026, with releases still landing through October. Pricing: the core library is free under a fair-code license (Apache 2.0 plus Commons Clause — free to use, not to resell); a separate paid VectorBT PRO tier adds extra features.

Efficient-frontier optimization, Black-Litterman allocation and Hierarchical Risk Parity all sit behind a few lines of PyPortfolioOpt — EfficientFrontier(mu, S).max_sharpe() is the whole call for a basic max-Sharpe portfolio. pip install PyPortfolioOpt is as far as setup goes, and with 6,000-plus stars and years of use in papers and tutorials, it's the library most portfolio-construction code ends up built on. Pricing: free and open source, MIT.

Freqtrade bundles backtesting, hyperparameter tuning, dry-run paper trading and live execution into one crypto trading bot, controllable from a Telegram chat or a web UI, against Binance, Kraken, OKX, Bybit and more. pip install freqtrade or the Docker quickstart gets a bot dry-running within minutes. With close to 56,000 stars and a release as recent as late September 2026, it's what most retail algo traders in crypto start from rather than building an order-routing layer themselves. Pricing: free and open source, GPL-3.0; you still pay whatever fees the exchange itself charges.

Kalshi's docs now cover two separate API lines: the original event-contract markets over REST, WebSocket and FIX, and a new perpetual-futures line built for the CFTC-regulated BTC perpetual it launched in June 2026, followed by gold and silver perpetuals in September. The official SDK got rewritten too — kalshi-python-sync and kalshi-python-async replace the deprecated original package and add RSA-PSS request signing. Pricing: no account or API fees; taker orders pay a per-contract fee that scales with price, and resting maker orders are free unless a specific market says otherwise.

Hyperliquid's own Python SDK wraps every REST and WebSocket endpoint for its non-custodial perpetuals and spot exchange, and handles the EIP-712 signing so placing a signed order doesn't mean implementing a signature scheme from scratch. pip install hyperliquid-python-sdk, point it at an API wallet key, and you're calling the exchange directly. Pricing: the SDK is free; the exchange charges 0.015%/0.045% maker/taker fees on perps at the base tier, dropping as volume and HYPE staking increase.

Portfolio Performance keeps every number — time-weighted returns, IRR, Sharpe ratio, tax-lot gains — in a local file on your own machine rather than a server somewhere, pulling prices from Yahoo, CoinGecko and other free sources. Download the desktop app and start adding accounts; there's no sign-up because there's no account to sign up for. It's been the default spreadsheet replacement in European investing forums for over a decade, and the latest release, 0.89.0, landed October 11, 2026. Pricing: free and open source, Eclipse Public License 1.0.

Bigcapital does double-entry bookkeeping, invoicing, bills and inventory behind a headless API — less a toy ledger, more a self-hosted stand-in for QuickBooks or Xero. docker compose up -d against the repo's compose file and it's running on your own server. Commits landed as recently as October 21, 2026, on top of more than 5,000 already in the history. Pricing: self-hosted core is free (AGPL-3.0); the vendor's own hosted cloud tiers run $20 to $60/month.

InvoicePlane handles client invoices, quotes and payment tracking from a self-hosted PHP install — unzip the release into a webroot and run the installer, no Docker required unless you want it. Version 1.7.2, released August 28, 2026, closed around 40 disclosed security issues, including a critical remote-code-execution bug and a Stripe overcharge flaw on zero-decimal currencies, while re-adding the Stripe, PayPal and Venmo payment processing that had been pulled during the audit. Pricing: free and open source, MIT.

Daloopa reads XBRL filings, PDFs, investor decks and transcripts and turns them into more than 1,300 standardized, source-linked KPIs across 6,000-plus tickers, available through a 37-endpoint REST API, an Excel add-in, or its own MCP server. Request access through the API product page; docs.daloopa.com covers the rest. The MCP side is the newest piece — a 2026 expansion added connectors for ChatGPT and Codex along with more than 20 prebuilt financial-analysis skills. Pricing: no published price; access is demo- and account-gated through sales.

This MCP server exposes 130 tools covering SEC filings, 13F holdings, insider and congressional trades, earnings-call transcripts, options chains and FRED macro series, so an agent can ask for a balance sheet and get XBRL-exact numbers instead of a summarized guess. Run claude mcp add --transport http equibles https://mcp.equibles.com/mcp against the hosted version, or clone the repo and self-host it with Docker Compose. The project only started in July 2026 and was still being pushed to as recently as October 19. Pricing: hosted free tier covers 100 requests/day with no card; self-hosting the AGPL-3.0 engine is free, and paid Plus/Pro hosted tiers scale up to 100,000 requests/day.

FinanceBenchmark tracks how more than 50 language models perform across 42 finance-specific tests — document analysis, numerical reasoning, agentic finance tasks — rather than taking a vendor's word for which model handles filings best. Browse the leaderboard directly or pull the same scores from its JSON data API. A CorpFin benchmark for long credit-agreement comprehension, plus updated scores for newer models, both landed in the site's October 2026 update. Pricing: free to browse and query; no license is published for the underlying benchmark data, so check before any commercial reuse.

Fineract is a core banking engine — clients, loans, savings, deposits, general ledger — exposed as a REST API and governed by the Apache Software Foundation rather than a single vendor. docker-compose up gets an instance running, and from there it's calls against the API. It's been the plumbing of choice for microfinance institutions and credit unions building lending products for over a decade, with nearly 12,000 commits and none of the usual VC-backed churn. Pricing: free and open source, Apache License 2.0.

Hyperswitch is a Rust-built payment orchestration layer that routes transactions across more than 100 processors with its own retry logic and PCI-compliant vaulting, so a checkout doesn't have to hard-code a single processor's API. docker-compose up runs the whole stack locally before you touch the hosted version. In July 2026, Recurly announced it was embedding Hyperswitch into its own subscription-billing platform through a new "Platform Organization" mode — a sign the project is becoming infrastructure other billing platforms build on, not just something a merchant installs directly. Pricing: free and open source, Apache 2.0, self-hosted; the hosted cloud version bills by usage.

Lago meters usage events and turns them into invoices through Stripe or Adyen — the layer under consumption-based pricing for anything billed by API call, token or compute hour. git clone the repo and follow the self-hosted deployment guide for Docker, or run the bundled compose file to try it locally first. Mistral AI, Groq and Synthesia all use it for billing infrastructure, and it now ships an MCP server alongside its REST API and CLI. Pricing: self-hosted core is free (AGPL-3.0); the hosted Cloud plan is free up to $250,000 in invoiced revenue, then 0.75% of volume.

Helius runs the RPC nodes, webhooks and streaming layer that most Solana-facing apps end up calling instead of hitting a public node directly — LaserStream for gRPC streaming, Sender for low-latency transaction delivery, plus archival query APIs. Sign up and a dashboard key is ready in under ten seconds, no card needed for the free tier. A 2026 acquisition of Light Protocol folded ZK-compression tooling into the platform on top of the RPC 2.0 work it did with the Solana Foundation and Jupiter in April. Pricing: free tier gives 1 million credits/month at 10 requests/second; the Developer plan starts at $49/month for 10 million credits and 50 requests/second.

Ponder indexes EVM contract events into a Postgres-backed API you query over GraphQL or SQL, with a dev workflow built around hot reloading instead of a full resync every time a handler changes. create-ponder scaffolds a project, and from there it's config in ponder.config.ts and pnpm dev. The Monad Foundation acquired the team behind it in February 2026 to build out EVM indexing infrastructure, and the project kept shipping since — v0.17.10 went out in September. Pricing: free and open source, MIT, self-hosted.

Turnkey creates and signs wallets across EVM, Solana and Bitcoin inside secure enclaves rather than holding keys itself, with SDKs in TypeScript, Swift, Kotlin, Python, Go and Ruby covering the policy controls around who can sign what. The docs walk through standing up a mobile wallet in under seven minutes. A $12.5 million strategic round in May 2026 from Circle Ventures and Sequoia is funding "Verifiable Cloud," a cryptographically attested signing layer that's been in private beta since late 2025 and is expanding toward a public launch. Pricing: a free developer tier exists; production access is sales-assisted with no published self-serve price.

Stock Rover screens more than 10,000 stocks across 800-plus metrics and lines up tickers, ETFs and mutual funds side by side in the same comparison table, the kind of fundamentals-first research most free screeners don't attempt. Start a 14-day trial with no card required; after that there's no permanent free tier, just a limited free account. A May 2026 overhaul added a new dashboard, 80 additional screeners and 20 years of historical fundamentals, with a July follow-up adding fund reports and 30 years of dividend history. Pricing: no lasting free tier; paid plans run Premium $34/month, Premium Plus $70/month, Ultimate $99/month, up to Ultimate Pro at $199/month.

This Python package calls TradingView's own screener API directly instead of scraping its pages, returning results as pandas DataFrames across more than 3,000 fields spanning stocks, crypto, forex, options and futures. pip install tradingview-screener, and its stocks(), crypto() and options() factory functions mirror the same filters TradingView's own screener pages expose — those shipped in v3.2.0 back in May 2026, with a dependency refresh following in June. Pricing: free and open source, MIT; the data depth you get still depends on whether the underlying TradingView account is free or paid.

Wisesheets pulls 30-plus years of financial statements, ratios and price history straight into Excel or Google Sheets formulas, so building a comparables model doesn't start with exporting CSVs. A free trial runs by email with no card, and the spreadsheet functions work alongside 30-plus broker integrations. It added real-time options-chain data to its formulas in March 2026 and extended live coverage to crypto, commodities, forex and indices in an October changelog update, serving more than 70,000 users at this point. Pricing: no permanent free tier; Pro runs $60/year, Elite $120/year, Enterprise is custom-priced for commercial and team use.
