x402 video

x402-video MCP server

Give any MCP-capable agent (Claude Code, Claude Desktop, Cursor, ...) the ability to generate AI videos and pay per call — USDC on Base over the x402 protocol. No accounts, no API keys, no credit cards.

quote_price → generate_video (pays exact USDC quote, gasless) → get_job → video_url

Backed by x402video.com: ~$0.45 for a 5s 720p clip, custom 4–15s up to 1080p with optional audio ($0.13–$4.62). Prompts are screened before payment — rejected requests are never charged.

Tools

Tool	Cost	What
list_skus	free	Live catalog + current USD prices
get_stats	free	Public reliability stats (success rate, p50 generation time)
quote_price	free	Exact USDC quote for a request, without paying
generate_video	paid	Quote → spend-guard check → pay → job_id
get_job	free	Poll status; returns video_url on success (24h link)
submit_feedback	free	Tell humans: price / missing feature / quality / bug / cheaper source

Setup

You need a dedicated spending wallet with a few USDC on Base (8453). Never use your main wallet — see the 5-minute getting-started guide.

Claude Code

claude mcp add x402-video \
  --env BUYER_PRIVATE_KEY=0xYOUR_SPENDING_WALLET_KEY \
  -- npx -y x402-video-mcp

Claude Desktop / Cursor (JSON)

{
  "mcpServers": {
    "x402-video": {
      "command": "npx",
      "args": ["-y", "x402-video-mcp"],
      "env": {
        "BUYER_PRIVATE_KEY": "0xYOUR_SPENDING_WALLET_KEY"
      }
    }
  }
}

Without BUYER_PRIVATE_KEY the free tools (catalog, quotes, job polling, feedback) still work; only generate_video requires the wallet.

Feedback (free)

Agents can report product needs without paying:

submit_feedback({
  message: "Need wait_for_job so I don't burn tokens polling",
  category: "feature",
  suggested_price_usd: 0.5
})

Categories: pricing | feature | quality | bug | source | other. Also available as raw HTTP: POST https://api.x402video.com/feedback.

Environment variables

Var	Default
BUYER_PRIVATE_KEY	—	Spending wallet key (USDC on Base). Required only for generate_video.
MAX_USD_PER_CALL	5	Hard spend guard — generate_video refuses quotes above this.
GATEWAY_URL	https://api.x402video.com	Point at another gateway instance.

How payment works

1. The tool POSTs your request unpaid; the gateway answers HTTP 402 with the exact USDC amount for that request (a free quote).
2. If the quote is within MAX_USD_PER_CALL, the request is retried with an x402 payment header — an EIP-3009 signature, so the buyer pays no gas.
3. You get a job_id; generation takes ~2 minutes (p50). Poll get_job, download video_url within 24h.
