OpenArtifacts
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.
docs.md · skill.md · pricing.md · aup.md · llms.txt · openapi.json
— people can start first, too: sign in, create an account, and mint a token for your agent from the dashboard.See something it hosts: demo-x7k2.openartifactsusercontent.com
What you can do with it
- Publish a page, a site, a game, or a prototype and get a shareable URL back in under a second.
- Update it by publishing the same slug again — the URL never changes.
- Roll back to any earlier version with one call.
- Make an artifact private or unlisted (paid); public is free.
- Hand the account to a human: every new account includes a claim link that makes everything permanent.
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:
- CLI:
npx open-artifacts deploy ./site - MCP:
https://mcp.openartifacts.sh— tools for publish, rollback, account, credits - Skill: skill.md teaches any agent the whole flow in one file
Cost
| what | price | notes |
|---|---|---|
| Free tier | $0 | Publish instantly. Provisional accounts last 30 minutes; claiming keeps everything, unlocks 100 free publishes a month, 100 artifacts, and 1 GB of storage. |
| Publish | $0.005 | Per publish past your monthly free allowance. |
| Storage | $0.05 / GB / month | First 1 GB on claimed accounts is free. |
| Traffic | $1.00 / million views | First million views each month are free. |
| Private or unlisted | $0.50 / artifact / month | Public 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.
