Questflow AI swarm agent: tweet, meme, image generation, and market analysis via x402 micropayment
What it does
This Questflow x402 endpoint exposes an AI agent swarm that can compose tweets, generate memes and images, analyze market trends, and perform other multi-capability tasks. The endpoint accepts a simple POST with a text prompt in the `input` field and 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 charge of 0.50 USDC per request (500000 in 6-decimal units) and a generous timeout of 1200 seconds.
Questflow positions itself as an AI agent economy platform that aggregates onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs) and provides autonomous AI "clones" for trading, content creation, and signal generation. This particular swarm endpoint appears to be a general-purpose agent that handles creative and analytical tasks based on the user's natural-language input.
Documentation is minimal — there is no OpenAPI spec, no dedicated docs page, and no detailed schema beyond what the x402 challenge header provides. The input/output contract is straightforward (string in, string out), but the range of supported tasks and quality of responses cannot be verified from available materials alone.
Capabilities
Use cases
- —Generate social media tweets from a text prompt
- —Create memes or images on demand via natural language
- —Analyze crypto or prediction market trends
- —Automate content creation tasks through an AI agent swarm
- —Integrate pay-per-use AI capabilities into agent workflows
Fit
Best for
- —Developers building agent-to-agent workflows that need creative or analytical AI tasks
- —Users who want pay-per-call AI content generation without subscriptions
- —Crypto-native applications needing x402-compatible AI endpoints
Not for
- —Users needing detailed, documented API contracts with guaranteed output schemas
- —Applications requiring deterministic or structured JSON responses
- —High-volume batch processing where per-call USDC payments are impractical

}Endpoint
Quality
The x402 challenge provides a basic input/output schema (string in, string out) and pricing info, but there is no OpenAPI spec, no docs page, no usage examples, and no detailed documentation. The capabilities described in the title are broad and unverifiable. Significant inference was required.
Warnings
- —No OpenAPI or dedicated API documentation available
- —No docs, pricing, or README pages found on the API domain
- —Output quality and supported task range cannot be verified from available materials
- —The response schema is a single string with no structured format guarantee
- —Maximum timeout of 1200 seconds suggests potentially long-running requests
