Top 10 crypto losers dashboard: 24h price declines, volumes, and market cap rankings via x402 payment.
What it does
This x402-payable endpoint returns a dashboard of the top 10 cryptocurrencies with the largest price declines over the past 24 hours. The response includes current prices, percentage changes, trading volumes, and market cap rankings, giving a snapshot of the day's biggest market losers.
The endpoint is hosted by Questflow on their development API server and accepts a POST request with a simple text input field. Payment is handled via the x402 protocol on the Base Sepolia testnet using USDC, with a maximum cost of 0.5 USDC per request. The agent has a maximum timeout of 1200 seconds, suggesting it performs real-time data gathering or aggregation before returning results.
Questflow is a platform for AI agent "clones" that aggregate data across crypto markets including Polymarket, Pump.fun, OKX, and others. This particular agent appears to be a specialized swarm agent focused on crypto market downturn analysis. Note that this is a development/testnet endpoint (Base Sepolia), so it may not be production-stable and the USDC used is testnet USDC.

Quality
No OpenAPI schema, no docs endpoint, no example responses available. The output schema is minimal (single string input/output). The endpoint is on a dev/testnet domain with testnet USDC. Most details about response format are inferred from the description.
Warnings
- —Development/testnet endpoint (Base Sepolia) — not production-ready
- —No OpenAPI or detailed documentation available
- —Response format is unstructured (single string) — actual content and structure are unknown
- —Testnet USDC payment — real funds are not required but endpoint stability is not guaranteed
- —Maximum timeout of 1200 seconds (20 minutes) suggests potentially slow responses
