Crypto alpha intelligence agent — trending tokens, airdrops, and real-time market insights via x402 micropayment.
What it does
This Questflow x402 endpoint exposes an AI-powered crypto alpha intelligence agent. You send a natural-language message and receive a text response covering trending tokens, new airdrops, and real-time market insights. The agent is part of Questflow's "AI Clone" swarm platform, which aggregates data from sources like Polymarket, Pump.fun, OKX, and Opinion Labs to scan onchain markets continuously.
The endpoint accepts a POST request with a JSON body containing an `input` string field (your message to the agent) and returns a JSON object with a `response` string field. Payment is handled via the x402 protocol on the Base network using USDC (asset 0x8335…2913), with a maximum charge of 0.50 USDC per request (500000 in 6-decimal units). The maximum timeout for a response is 1200 seconds (20 minutes), suggesting the agent may perform non-trivial research or aggregation before replying.
Documentation beyond the x402 challenge and the Questflow landing page is sparse. There is no public OpenAPI spec, no dedicated docs route, and no pricing page on the API host. The schema and payment details are derived entirely from the 402 challenge payload. The endpoint is live and responds with a valid x402 challenge on POST.
Capabilities
Use cases
- —Ask the agent about currently trending tokens and get a summarized response
- —Discover new airdrop opportunities by querying the agent in natural language
- —Get real-time market sentiment or whale-movement insights for a specific token
- —Integrate crypto alpha intelligence into an automated trading or alerting pipeline
- —Query for cross-platform market data aggregated from Polymarket, Pump.fun, OKX, etc.
Fit
Best for
- —Developers building crypto trading bots that need on-demand market intelligence
- —AI agent pipelines that need pay-per-query crypto alpha without API key management
- —Users wanting a single natural-language interface to aggregated onchain market data
Not for
- —High-frequency trading requiring sub-second latency (max timeout is 1200s)
- —Users needing structured, machine-readable market data feeds rather than natural-language responses
- —Non-crypto use cases — the agent is specialized for crypto markets

}Endpoint
Quality
The endpoint is live with a valid x402 402 challenge, and the outputSchema clearly defines input/output fields. However, there is no OpenAPI spec, no dedicated documentation, no usage examples from the provider, and the response format is inferred. The description is taken almost verbatim from the challenge payload with no additional detail available.
Warnings
- —No public API documentation or OpenAPI spec available
- —Response content and format are inferred from the outputSchema description — no real example response was captured
- —Max timeout of 1200 seconds suggests potentially long response times
- —Example response JSON is fabricated to illustrate the schema; actual responses may differ
