Pay-per-query agent that visualizes 24-hour trading volume for the top 10 cryptocurrencies.
What it does
This x402-enabled endpoint exposes a Questflow-powered AI agent that generates an interactive dashboard showing the 24-hour trading volume of the top 10 cryptocurrencies. The agent accepts a text prompt via a POST request and returns a response describing or rendering dashboard data including line charts (via Recharts), hover tooltips, responsive layout, and detailed data tables for market analysis.
The endpoint uses the x402 payment protocol on the Base Sepolia testnet, accepting USDC payments with a maximum amount of 500,000 units (likely 0.50 USDC given 6-decimal USDC). The payment scheme is "exact" and the maximum timeout is 1,200 seconds. There is no OpenAPI spec, no dedicated documentation page, and no pricing page beyond what the x402 challenge header provides.
The parent platform, Questflow, is an AI agent marketplace focused on crypto trading, prediction markets, and on-chain analytics. This particular agent appears to be a single-purpose swarm agent identified by its QRN. Because the endpoint is on a dev subdomain (`api-dev`) and uses the Base Sepolia testnet (a test network), this should be treated as a development/staging deployment rather than a production service.
Capabilities
Use cases
- —Querying an AI agent for a snapshot of 24-hour trading volume across top cryptocurrencies
- —Embedding crypto volume dashboards into agent workflows via x402 micropayments
- —Automated market monitoring that summarizes top-coin volume trends
Fit
Best for
- —Agents needing on-demand crypto volume summaries
- —Developers prototyping x402 payment flows with a crypto data agent
- —Quick visual market analysis of top cryptocurrency trading activity
Not for
- —Production trading systems (this is on a testnet/dev endpoint)
- —Historical backtesting or bulk data export
- —Non-crypto data visualization needs

Request
{
"input": "Show me the 24h trading volume for the top 10 cryptocurrencies"
}Response

"response": "Here is the 24-hour trading volume dashboard for the top 10 cryptocurrencies: BTC: $28.3B, ETH: $14.1B, ..."
}Endpoint
Quality
No OpenAPI spec, no documentation pages, no examples beyond the x402 challenge metadata. The endpoint is on a dev subdomain using a testnet, suggesting it is not production-ready. The output schema is minimal (single string response). Significant inference was required for the listing.
Warnings
- —Endpoint is on a dev subdomain (api-dev) and uses Base Sepolia testnet — not a production deployment
- —No OpenAPI specification or dedicated documentation available
- —Output is a single string field; dashboard visualization details (Recharts, tooltips) are described but not verifiable from the schema
- —Payment amount units are ambiguous (500000 could be 0.50 USDC with 6 decimals, but unconfirmed)
- —No /docs, /api, /pricing, or /README routes found
