Ethereum dashboard agent returning real-time price, market data, supply, charts, and exchange activity via x402 micropayment.
What it does
This x402-enabled endpoint exposes an AI agent that serves as a comprehensive Ethereum dashboard. It accepts a natural-language message (via a POST body with an "input" field) and returns a text response covering real-time ETH price, market data, supply metrics, historical charts, and exchange activity. The agent is hosted on Questflow's swarm infrastructure at a development API endpoint.
Payment is handled via the x402 protocol on the Base Sepolia testnet. The accepted asset is USDC (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e) with a maximum amount of 500,000 units (denominated in the token's smallest unit). The payment timeout is 1,200 seconds. Because this uses Base Sepolia (a testnet), the endpoint appears to be in a development or staging phase rather than production.
No dedicated API documentation, OpenAPI spec, or usage examples were found beyond the x402 challenge's outputSchema. The outputSchema indicates a simple request/response pattern: send a string prompt, receive a string response. The endpoint is live and returns a proper 402 challenge when called without payment.
Capabilities
Use cases
- —Querying current Ethereum price and market cap in natural language
- —Retrieving ETH supply metrics and historical price data
- —Getting a summary of Ethereum exchange activity for research or dashboards
- —Integrating Ethereum market intelligence into an AI agent workflow
- —Building automated crypto monitoring pipelines
Fit
Best for
- —Developers wanting a conversational interface to Ethereum market data
- —AI agents that need on-demand ETH analytics via micropayment
- —Prototyping crypto dashboard features using a testnet payment rail
Not for
- —Production financial applications requiring mainnet payment rails
- —Users needing raw structured data feeds (responses are natural-language strings)
- —High-frequency trading systems requiring sub-second latency

Request
{
"input": "What is the current Ethereum price and market cap?"
}Response
{
"response": "The current Ethereum (ETH) price is approximately $3,450 with a market capitalization of around $415 billion. 24-hour trading volume is $12.3 billion across major exchanges."
}Endpoint
Quality
The endpoint is live and returns a valid x402 challenge with an outputSchema, but there is no dedicated documentation, no OpenAPI spec, no usage examples, and the endpoint runs on a testnet (Base Sepolia), suggesting it is still in development. The response format and dashboard capabilities are inferred from the description and schema alone.
Warnings
- —Endpoint uses Base Sepolia testnet — not suitable for production payments
- —No API documentation or OpenAPI spec found
- —Response example is inferred; actual output format is unverified
- —Development/staging endpoint (api-dev subdomain) — availability may be unstable
