# Parsec Finance

> Parsec Finance is an institutional-grade on-chain analytics platform for DeFi and NFT markets, exposing a Pro GraphQL API for programmatic access to real-time on-chain market data across many EVM chains. Used by firms such as Polychain and Galaxy Digital.

Parsec's public API is a single GraphQL endpoint at https://api.parsec.finance/api/v2. Requests are POSTed with an `api_key` header (key prefix `par_ak_`); an API key is provisioned from the Parsec app under Settings -> Subscription and requires a Pro subscription. A first-party Python SDK (parsecfi) wraps the API.

## API
