x402-payable Web3 trading agent that responds to natural-language prompts about onchain markets.
What it does
Web3 Trader is an x402-enabled AI agent endpoint hosted on Questflow's infrastructure. It accepts a natural-language text input via HTTP POST and returns a string response from the agent. Payment is handled through the x402 protocol on the Base Sepolia testnet using USDC, with a maximum charge of 0.5 USDC per request.
The agent is part of Questflow's "AI Clone" platform, which aggregates onchain markets such as Polymarket, Pump.fun, Opinion Labs, and OKX. Based on the platform's marketing, these agents scan prediction markets, meme-coin launches, and other crypto opportunities. However, the specific capabilities of this particular "Web3 Trader" swarm agent are not documented beyond its name and the minimal input/output schema exposed in the x402 challenge.
The endpoint is currently on a development/testnet domain (api-dev.intra-tls2.dctx.link) and uses Base Sepolia (a testnet), which suggests it is not yet production-grade. No OpenAPI spec, detailed documentation, or usage examples are available. The output schema is simply a string response, so the depth and quality of the agent's answers are unknown without live testing.
Capabilities

- —Exploring x402-protocol payment flows on Base Sepolia testnet
Fit
Best for
- —Developers experimenting with x402 payment protocol for AI agents
- —Users wanting a conversational interface to Web3 market intelligence
- —Agent-to-agent workflows that need an onchain-aware trading sub-agent
Not for
- —Production trading with real funds (currently on testnet)
- —Users needing detailed, documented API schemas or guaranteed SLAs
- —Non-crypto use cases with no relation to onchain markets

}Endpoint
Quality
No OpenAPI spec, no documentation pages (all return 404), no usage examples, and the endpoint runs on a testnet (Base Sepolia). The only concrete technical information comes from the x402 challenge payload, which provides a minimal input/output schema. Significant inference was required for most fields.
Warnings
- —Endpoint is on a development domain (api-dev) and uses Base Sepolia testnet — not production-ready
- —No API documentation, OpenAPI spec, or detailed schema available
- —The example response is entirely fabricated for illustration; actual agent output is unknown
- —Description says 'Powered by Questflow' — a third-party platform whose reliability and uptime are unverified
- —maxTimeoutSeconds is 1200 (20 minutes), suggesting potentially very long response times
- —Financial/trading domain — outputs should not be treated as financial advice
