x402 Video — AI Video Generation (pay-per-call, no account)

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. Seedance 2.0, 5s 720p: Mini $0.67, Fast $1.05, Standard $1.33 per clip. Custom 4–15s with optional audio: Mini $0.26–$2.00 and Fast $0.40–$3.15 (480p/720p), Standard $0.49–$9.82 (up to 1080p). The exact USDC price is always the live 402 quote. Prompts are screened before payment; rejected requests are never charged.

Tools

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

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.
