The Metastreams API serves real-time and historical spot market data for tokens on Solana, Base, BNB Smart Chain, Robinhood Chain and Arc. Use it to build trading bots, terminals, dashboards, alerts and agents.

Get an API key

Every request needs a key. Here is how to get one.

Quickstart

Make your first request and open your first stream in a few minutes.

​
What you can read

Every response follows the same conventions: camelCase field names, timestamps in Unix milliseconds, and exact decimal strings for money. See Reading responses.

​
Base URLs

The OpenAPI document needs no key. Use it to generate a client in your language. Call every other path from a server you control: a key never belongs in browser or mobile code. See Keys belong on your backend.

​
Next steps
