Ephemeral File Hosting for AI Agents

What it does

Give agents a place to park files — PDFs, CSVs, images, logs — without provisioning S3 buckets, managing IAM policies, or handling cleanup. Files auto-expire after a configurable TTL (default: 1 hour). Access via a simple URL.

Why agents need this

• •Agents are stateless — they terminate after each invocation and lose local files
• •Agents run in sandboxes with no persistent disk or object storage access
• •Agents have no credentials to authenticate with S3/GCS/Azure
• •Cleaning up temporary files is a chore that every agent workflow needs

One API call. No SDK. No configuration.

curl -X POST https://www.agent-utils.com/api/file-host \
  -H "x-api-key: au_your_key" \
  -F "file=@report.csv" \
  -F "ttl=2"

import requests

resp = requests.post(
    "https://www.agent-utils.com/api/file-host",
    headers={"x-api-key": "au_your_key"},
    files={"file": open("report.csv", "rb")},
    data={"ttl": "2"},
)
file_url = resp.json()["data"]["url"]

const form = new FormData();
form.append("file", fs.createReadStream("report.csv"));
form.append("ttl", "2");

const res = await fetch("https://www.agent-utils.com/api/file-host", {
  method: "POST",
  headers: { "x-api-key": "au_your_key" },
  body: form,
});
const { data } = await res.json();
console.log(data.url); // https://www.agent-utils.com/api/file-host/abc123

Use cases

AgentUtils vs. alternatives

Traditional tools like AWS S3, Cloudflare R2, Filestack require SDK integration, credential management, and infrastructure setup. AgentUtils replaces all of that with a single HTTP call.
