MiniMax multimodal AI (image, video, TTS) via x402 micropayment on Questflow
What it does
This endpoint exposes a MiniMax-powered AI agent through the Questflow platform, accessible via the x402 payment protocol. MiniMax is described as an AI platform offering comprehensive multimodal capabilities including image generation, video generation, text-to-speech, and more. The agent is hosted at Questflow, which operates as an AI agent marketplace and execution layer on the Base blockchain.
To use the endpoint, you send a POST request with a JSON body containing an "input" field (your text prompt or message). Payment is made via the x402 protocol using USDC on the Base network, with a maximum cost of 0.1 USDC per request (100000 in raw units, 6 decimals). The agent responds with a string in the "response" field. The maximum timeout is 1200 seconds, suggesting that generation tasks (especially video or image) may take significant time.
Documentation is sparse — there is no OpenAPI spec, no dedicated docs page, and no detailed description of which specific MiniMax models or capabilities are exposed through this particular agent. The Questflow platform itself is primarily marketed as an "AI Clone" trading agent system, so this MiniMax agent appears to be one of many agents available on their x402 infrastructure. Without further documentation, it is unclear exactly which MiniMax features (image gen, video gen, TTS) are accessible through this single text-in/text-out interface.
Capabilities
Use cases
- —Generating images from text prompts via a pay-per-request model
- —Producing AI-generated video content
- —Converting text to speech using MiniMax models
- —Integrating multimodal AI into agent workflows with micropayments
Fit
Best for
- —Developers wanting pay-per-use multimodal AI without API keys
- —Agent-to-agent workflows needing x402-compatible AI endpoints
- —Quick prototyping with MiniMax capabilities via a simple POST interface
Not for
- —High-volume production workloads needing detailed SLAs and documentation
- —Users who need fine-grained control over specific MiniMax model parameters
- —Applications requiring sub-second latency (max timeout is 1200s)

}Endpoint
Quality
No OpenAPI spec, no docs page, no examples, and no detailed information about which MiniMax capabilities are actually exposed. The only concrete data comes from the x402 challenge header. The response format and actual multimodal capabilities are entirely inferred from the agent description.
Warnings
- —No OpenAPI or documentation available — /docs, /api, /pricing, /README all return 404
- —It is unclear which specific MiniMax models or features are accessible through this text-in/text-out interface
- —Example response is fabricated for illustration; actual response format is unknown
- —The Questflow platform is primarily a trading/clone agent platform; this AI agent may have limited support or maintenance
- —Max timeout of 1200 seconds suggests potentially very long response times
