Pay-per-query Bitcoin price dashboard agent returning real-time price, 24h change, market cap, volume, and 7-day chart data.
What it does
This x402-enabled endpoint exposes a Questflow-hosted AI agent that serves as a real-time Bitcoin price dashboard. When you send a text message (via POST with an `input` field), the agent responds with current Bitcoin price information including the current price, 24-hour change, market cap, trading volume, and 7-day price chart data, using green/red indicators and timestamped updates.
The endpoint operates on the x402 payment protocol over the Base Sepolia testnet, accepting USDC payments with a maximum cost of 0.50 USDC per request (500000 in token units). The payment is sent to address `0x76E0553ec2760ba0dB5af4ef0d9E9DA4066232A1`. The request timeout is set to 1200 seconds, suggesting the agent may perform non-trivial data fetching or processing before returning results.
The endpoint is hosted by Questflow, a platform focused on autonomous AI agents ("Clones") that aggregate data across onchain markets. No dedicated API documentation, OpenAPI spec, or usage examples are published for this specific endpoint. The output schema indicates a simple string response from the agent, so consumers should expect a text-based summary rather than structured numerical data. Because this runs on Base Sepolia (a testnet), it is likely intended for development or demonstration purposes rather than production use.
Capabilities
Use cases
- —Querying current Bitcoin price and market stats on demand via a pay-per-call model
- —Building agent-to-agent workflows that need live BTC market data
- —Prototyping x402 payment flows with a testnet crypto data endpoint
- —Embedding real-time Bitcoin summaries into chat or dashboard applications
Fit
Best for
- —Developers experimenting with x402 payment protocol on Base Sepolia
- —Agents needing a simple natural-language Bitcoin price summary
- —Quick prototyping of pay-per-query crypto data integrations
Not for
- —Production trading systems requiring structured, low-latency market data feeds
- —Historical Bitcoin price analysis or bulk data retrieval
- —Mainnet payment workflows (this uses Base Sepolia testnet)

Request
{
"input": "What is the current Bitcoin price?"
}Response
{
"response": "Bitcoin is currently trading at $68,432.15, up +2.3% in the last 24 hours. Market cap: $1.35T. 24h volume: $28.7B. The 7-day chart shows a steady upward trend."
}Endpoint
Quality
The endpoint is live (402 challenge confirmed) with a clear output schema, but there is no OpenAPI spec, no dedicated documentation, no usage examples, and the response format is only described as a generic string. The testnet-only payment network further limits practical utility.
Warnings
- —No OpenAPI spec or dedicated API documentation available
- —Runs on Base Sepolia testnet — not suitable for production payments
- —Response is an unstructured string; no guaranteed JSON schema for the Bitcoin data fields
- —Example response is inferred from the description — actual output format is unverified
