BubbleMarkets Developer API
The BubbleMarkets API returns live multi-asset market data as JSON from a single endpoint: GET https://bubblemarkets.com/api/v1/markets?category={crypto|stocks|etf|forex|forex_pairs|commodities|bonds|indices}&page={n}. Each asset in the response carries symbol, name, price, market cap, 24-hour volume and percentage change.
Authentication
Requests are authenticated with an API key sent in the x-api-key header. Keys are issued on the Professional plan and managed from this page once signed in. Responses are cached for about 60 seconds, which is also the refresh cadence of the underlying data.
Machine-readable specification
The full OpenAPI 3 specification is published at /openapi.json, and agent-facing notes are at /agents.txt and /llms.txt.
