AI agent that discovers trending crypto tokens and emails them to you, paid per-call via x402.
What it does
This Questflow x402 endpoint exposes an AI swarm agent that identifies "hot tokens" across crypto markets and delivers the results to your email inbox. It is hosted on Questflow's agent platform, which aggregates data from sources like Polymarket, Pump.fun, OKX, and other onchain markets. The agent scans for trending tokens, sentiment shifts, and whale activity, then compiles findings into an email report.
The endpoint accepts a POST request with a single required field — `input` (a string message to the agent, presumably including your email address and any filtering preferences). It returns a string `response` from the agent. Payment is handled via the x402 protocol on the Base network using USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), with a maximum cost of 500,000 units (0.50 USDC) per request and a timeout of up to 1200 seconds.
Documentation for this specific endpoint is minimal — there is no OpenAPI spec, no dedicated docs page, and no usage examples beyond the x402 challenge schema. The Questflow platform itself focuses on autonomous AI "Clones" that trade and scan onchain markets, so this agent likely leverages similar market-scanning infrastructure. Users should be aware that the exact behavior of the agent (which tokens it selects, how it formats the email, what email service it uses) is not documented and must be inferred from the agent's response.

Quality
The endpoint is live (402 challenge confirmed) with a clear outputSchema, but there are no docs, no usage examples, and no detailed description of agent behavior. The example response is inferred, not sourced. Pricing is only derivable from the x402 challenge.
Warnings
- —No dedicated documentation or OpenAPI spec available for this endpoint
- —Agent behavior (email formatting, token selection criteria, supported email providers) is undocumented
- —Example response is inferred — actual output format may differ
- —The endpoint description is vague; exact functionality must be discovered by calling the agent
