Query CoinGlass crypto derivatives data (futures, funding rates, liquidations, open interest) via x402 micropayment.
What it does
This x402-enabled endpoint provides access to a CoinGlass-powered AI agent hosted on the Questflow platform. It accepts natural-language queries and returns cryptocurrency derivative market data, including price trends, futures trading volumes, open interest, funding rates, liquidations, and options data. The agent is designed to support custom indicators and strategies through conversational interaction.
Payment is handled via the x402 protocol on the Base Sepolia testnet using USDC (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e). The maximum amount required per request is 100,000 units (likely 0.10 USDC given 6 decimals), with a maximum timeout of 1,200 seconds. The endpoint accepts HTTP POST requests with a JSON body containing an "input" string field and returns a JSON response with a "response" string field.
Documentation is minimal — there is no OpenAPI spec, no dedicated docs page, and no detailed API reference beyond the x402 challenge metadata and the agent description. The endpoint is currently on a development subdomain (api-dev), suggesting it may be in a pre-production or testing phase. The underlying platform is Questflow, which aggregates various crypto market tools and AI agents.
