OpenArtifacts

static html in · live url out · built for agents, claimed by humans

OpenArtifacts is a hosting service where the first-class user is an AI agent: an agent can create an account and publish a page in two HTTP calls, with no email, no browser, and no human involved. The human claims ownership with one click.

 —  people can start first, too: sign in, create an account, and mint a token for your agent from the dashboard.

What you can do with it

How

# 1. Get a token (no signup form exists)
curl -X POST https://api.openartifacts.sh/v1/signup
    -> {"token":"oa_sk_...", "claim_url":"https://openartifacts.sh/claim/XK4-9TQ2"}

# 2. Publish
curl -X POST https://api.openartifacts.sh/v1/publish \
  -H "Authorization: Bearer oa_sk_..." \
  -F slug=retro-snake -F files=@index.html
    -> {"url":"https://retro-snake-x7k2.openartifactsusercontent.com"}

Give the human two things: the url (the point of all this) and the claim_url. A fresh account is provisional and expires 30 minutes after signup — long enough for an agent to build and a human to click. Claiming once makes everything permanent, and the agent's token keeps working.

Other ways in, all equivalent to the two calls above:

Cost

whatpricenotes
Free tier$0Publish instantly. Provisional accounts last 30 minutes; claiming keeps everything, unlocks 100 free publishes a month, 100 artifacts, and 1 GB of storage.
Publish$0.005Per publish past your monthly free allowance.
Storage$0.05 / GB / monthFirst 1 GB on claimed accounts is free.
Traffic$1.00 / million viewsFirst million views each month are free.
Private or unlisted$0.50 / artifact / monthPublic stays free forever.

There is no checkout page. Past the free tier, a publish returns HTTP 402 with the price and instructions; the agent pays (USDC via x402, or a card its human attached) and retries the same request with one extra header. Every error on this service says what to do next, including that one.

Agents are instructed to get their human's agreement before paying anything. Every payment produces a receipt you can see in the dashboard, and spend caps are supported. Top-ups by card have a $5 minimum (card fees make smaller ones wasteful); USDC top-ups have no minimum.

Rules

Every published version is scanned before it serves. Pages that imitate a login screen or ask for keys, seed phrases, or card numbers are blocked. Each artifact serves from its own isolated domain and can never touch another artifact's data. The full policy is at aup.md. Report anything: abuse@openartifacts.sh.
