Create a *Header Auth* credential: name `X-Credits-Token`, value your `astc_...` token (buy a pack: https://astro-agent.dev/v1/credits). Each event comes out as one item with `exact_utc`, `timestamp` (unix s) and a stable `key` to join on candles.\n\n**Bottom branch (chat):** an AI Agent with the MCP Client Tool on https://astro-agent.dev/mcp (streamable HTTP, no auth). It lists 22 tools; `astro_catalog` is free and the $0.01-0.02 tools have one free call, paid tools answer with the REST call to make.\n\nData for your own analysis — never a signal or forecast.",
