Pay-per-query deep Web3 research agent via x402 on Base
What it does
Deep WEB3 Research is an x402-enabled AI agent endpoint hosted by Questflow that performs deep research across Web3 topics. It accepts a natural-language prompt and returns a text response generated by a multi-agent swarm. Payment is handled via the x402 protocol on the Base network using USDC (asset 0x8335…2913), with a maximum cost of 0.50 USDC per request and a timeout of up to 1200 seconds (20 minutes).
The endpoint accepts a POST request with a JSON body containing a single required field, `input` (string), which is your message or research query to the agent. The response includes a `response` field (string) with the agent's answer. The x402 challenge is live and well-formed, confirming the endpoint is operational.
Questflow is a platform focused on autonomous AI agents ("Clones") that scan and trade across onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. This particular swarm endpoint is designed for Web3 research rather than trading. Documentation beyond the x402 challenge itself is sparse — no OpenAPI spec, no dedicated docs page, and no detailed description of what "deep WEB3 research" covers or which data sources the swarm consults. Users should expect a general-purpose Web3 research assistant but should verify output quality empirically.
Capabilities
Use cases
- —Querying current Web3 trends, protocols, or token information via a single API call
- —Integrating deep Web3 research into autonomous agent workflows that support x402 payments
- —Augmenting crypto trading bots with on-demand research context
- —Building dashboards or newsletters that pull Web3 intelligence programmatically
Fit
Best for
- —Developers building Web3-native applications that need on-demand research
- —Agent-to-agent workflows where x402 micropayments are preferred over API keys
- —Quick ad-hoc Web3 research queries without managing multiple data source integrations
Not for
- —Non-crypto or general-purpose research unrelated to Web3
- —Users who need deterministic, structured data feeds rather than natural-language responses
- —High-frequency, low-latency use cases (timeout up to 20 minutes)

Request
{
"input": "What are the top Layer 2 rollups by TVL this week?"
}Response
{
"response": "As of this week, the top Layer 2 rollups by Total Value Locked (TVL) are: 1. Arbitrum One (~$X.XX B), 2. Base (~$X.XX B), 3. Optimism (~$X.XX B)... [detailed analysis follows]"
}Endpoint
Quality
The x402 challenge is live and includes a clear outputSchema with input/output definitions, confirming the endpoint works. However, there is no OpenAPI spec, no dedicated documentation, no usage examples, and the description of what 'deep WEB3 research' actually entails is absent. Pricing is inferrable from the challenge but not documented elsewhere.
Warnings
- —No OpenAPI or dedicated API documentation available
- —No detailed description of data sources or research methodology behind the swarm
- —Example response is inferred/illustrative — actual output format and depth are unknown
- —Maximum timeout of 1200 seconds suggests potentially long response times
