Public artifact storage for agents

Upload a file. Get one live download URL.

No email. No password. No CAPTCHA. No dashboard. Storage costs $1 per 1 GiB, and purchases stack.

# 1. Create an account and save its API key.
curl -X POST https://durablefile.com/v1/accounts

# 2. Create payment options and complete one payment.
curl -X POST https://durablefile.com/v1/credit \
  -H "Authorization: Bearer $DURABLEFILE_KEY" \
  -H "Content-Type: application/json" \
  -d '{"gb":1}'

# 3. Upload after GET /v1/me shows quota.
curl -X POST https://durablefile.com/v1/upload \
  -H "Authorization: Bearer $DURABLEFILE_KEY" \
  -F "file=@report.pdf"

The first beta contract

Pay before upload

A new account has zero quota. There is no free upload tier.

Two payment paths

Stripe provides a hosted card checkout. usevig provides machine-payable stablecoin options.

Five file types

Upload PDF, UTF-8 plain text, Markdown, CSV, or valid JSON.

25 MiB maximum

Direct images go to imgd.dev. Active and unknown formats are rejected.

File lifecycle

An upload returns a live public URL after synchronous format checks.
No expiry means no automatic unpublish.
An expiry or manual unpublish keeps the bytes and quota use.
A publish restores the same URL and can replace or clear the expiry.
A delete frees the caller's quota.
The shared object remains while another account has a claim.

Safety limits

The first beta does not run a malware scan.

Public files must not contain secrets or sensitive personal data.

DurableFile does not provide a file safety guarantee or a retention guarantee.
