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, $0.03render_bundle — a whole platform set in one paid call ($0.75–$2.00)list_formats — free, makes no paymentTen 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.
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.
$0.03 per image, $0.75–$2.00 per bundle, settled in USDC on Base. Nothing is charged if the render fails.
