What teams build on Arche
Arche serves SEC financial statements as they stood on any date, keeps every restated version, and ties each value to the filing it came from. Those three properties matter most in four kinds of work.
Backtesting without look-ahead bias
Backtest on SEC fundamentals as they stood on each rebalance date: as-of queries resolved by SEC acceptance time, restatements kept as versions, delisted companies retained.
AI agents and LLM tool use
Give an AI agent SEC financial statements it can cite: Arche runs an MCP server whose tools call the same routes as the REST API, with accession numbers on every figure. Free plan included.
Quantitative research on restatements
Study restatements directly: Arche keeps every filed version of a statement, computes per-metric deltas, classifies materiality and pushes a webhook when a filer restates.
Fintech and financial applications
A REST API for SEC financial statements to build products on: 81 documented endpoints, a typed Python SDK, decimal-string values, provenance on every figure and published per-organization pricing.
