getdigitalcraft-render (MCP)

Deterministic social image rendering for AI agents. Spec in, PNG out, with typography that is exactly the text you asked for — image models still garble lettering; this cannot, because it isn't a model. Paid per call in USDC on Base over x402, so there is no account, no API key and no subscription.

• render_image — one format, $0.03

• render_bundle — a whole platform set in one paid call ($0.75–$2.00)

• list_formats — free, makes no payment

Ten formats: Instagram square / portrait / story, Facebook feed, Open Graph, X card, LinkedIn, Pinterest pin, YouTube thumbnail, quote card.

X402_PRIVATE_KEY is your wallet, holding USDC on Base. It never leaves your machine — this server signs payments locally and sends only the authorization. Use a wallet funded with what you're willing to spend on rendering, not your main one.

Without the key the server still starts and list_formats still answers; only paying is disabled.

Why it's deterministic

satori renders HTML to SVG, resvg rasterises it. No diffusion, no GPU, no sampling — so the same spec always yields the same pixels, and the headline you pass is the headline that appears. Roughly 250ms warm.

Cost

$0.03 per image, $0.75–$2.00 per bundle, settled in USDC on Base. Nothing is charged if the render fails.
