AI-powered crypto market analysis with TOON metrics and commentary via x402 micropayment.
What it does
CryptoBuddy is an x402-enabled endpoint that provides AI-powered cryptocurrency market analysis. By sending a POST request with a coin symbol (e.g., BTC, ETH, SOL), the service returns a structured response containing TOON metrics (an object with market data) and a written AI-generated report with detailed market commentary.
The endpoint is hosted on Render and accepts payment via the x402 protocol on the Base network using USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). Each request costs up to 1,000,000 units (1 USDC, assuming 6-decimal USDC) with a maximum timeout of 60 seconds. The service self-describes as providing "AI-powered trading signals, market insight, and predictive analysis."
Documentation is minimal — there is no OpenAPI spec, no docs page, and no README available. The output schema indicates the response includes a `toon` object and a `report` string, but the internal structure of the TOON metrics object is not further specified. The input requires a single query parameter `symbol` (string, required) representing the cryptocurrency ticker.

Quality
The endpoint is live and returns a valid x402 challenge with an output schema, but documentation is entirely absent — no OpenAPI spec, no docs page, no README. The TOON metrics object structure is unspecified. The example response is inferred/illustrative since no actual paid response was captured.
Warnings
- —No documentation available at /docs, /api, /pricing, or /README
- —The internal structure of the 'toon' metrics object is not documented in the output schema
- —Example response JSON is illustrative and inferred — actual response structure may differ
- —Service is hosted on Render free/hobby tier (onrender.com) which may have cold-start latency
- —This is a financial analysis tool — outputs should not be treated as investment advice
