# hello.new > Temporary internet resources for agents. One anonymous HTTP call gives an agent an upload link, a shared page, a webhook URL or a website. No account, no API key. Everything expires in 24 hours. API origin: https://api.hello.new. Create with POST /upload, POST /share, POST /webhook, POST /site (a static site, served at https://{id}.hellonew.app; on an account it can ask visitors for a password, sent as password in the JSON body). Each response has a public url, a private key (shown once) and an expires_at. With an account key (Authorization: Bearer hk_…, never in ?key=, which takes only a link key) links live at hello.new/@username/name and stay, up to 1000 links and 1 GB per account; anonymous responses carry a claim_url that lets the user keep the link. Send X-Hello-Client with the name of your runtime. OpenAPI: https://api.hello.new/openapi.json.
