Pay-per-request AI image, video, and audio generation via Wavespeed.ai on Base
What it does
This x402-enabled endpoint at amn-animations-0xbuildr.replit.app/api/generate provides AI-powered media generation (images, videos, and audio) using Wavespeed.ai as the underlying engine. It accepts POST requests and requires an x402 payment header with USDC on the Base network. The maximum cost per request is 0.45 USDC (450000 in raw units of the 6-decimal USDC token), with a timeout of up to 300 seconds.
The endpoint is live and returns a valid x402 challenge (version 1) when called without payment. However, documentation is essentially nonexistent — there is no OpenAPI spec, no /docs page, no README, and no publicly available API reference describing the expected request body or response format. The parent site is "AMN - Animated Meme Network," which appears to be a memecoin-adjacent AI animation education platform. The API endpoint itself is the only programmatic interface exposed.
Due to the complete lack of request/response schema documentation, callers will need to experiment or contact the provider to determine the correct payload structure. The Wavespeed.ai backend suggests support for text-to-image, text-to-video, and text-to-audio generation, but specific model names, parameters, and output formats are unknown from available materials.
Capabilities
Use cases
- —Generating AI images from text prompts with per-request USDC payment
- —Creating short AI-generated video clips programmatically
- —Producing AI audio content via a pay-as-you-go API
- —Integrating AI media generation into agent workflows that support x402 payments
Fit
Best for
- —Agents or apps needing on-demand AI media generation with crypto micropayments
- —Developers already using x402 payment flows on Base
- —Quick prototyping of AI-generated visual or audio content without subscription commitments
Not for
- —Production workloads requiring documented, stable API contracts
- —Users who need detailed control over model parameters (no schema available)
- —Anyone without USDC on Base or unfamiliar with x402 payment protocol

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it is operational. However, there is zero API documentation: no OpenAPI spec, no docs page, no request/response schema, and no examples. The request body format is entirely unknown and the example above is speculative. The parent site is a memecoin animation community with no technical API docs.
Warnings
- —No API documentation, OpenAPI spec, or request/response schema is available
- —Request body format is unknown — the example_request_json is speculative based on the description mentioning Wavespeed.ai
- —The parent site (AMN - Animated Meme Network) appears to be a memecoin-related project; assess provider stability accordingly
- —No /docs, /api, /pricing, or /README pages exist (all return 404)
- —The mimeType field in the x402 challenge is empty, giving no hint about response content type
