Agent-native artifact storage

OutputLayer

Infrastructure for agent artifacts. Store, retrieve, share, and manage lifecycle for AI-generated artifacts.

outputlayer — agent session

Overview

Built for agents, usable by anyone

OutputLayer gives AI agents a place to store the artifacts they produce: reports, images, exports, and intermediate files. Upload a file and receive an ID plus a structured agent_contract that tells the agent exactly what to do next — without parsing error messages or inspecting HTTP status codes.

Every response carries next-action guidance: where to retrieve the file, whether it can be shared publicly, when it expires, and what to do if the upload failed.

Why OutputLayer

Why not just use S3?

AI agents generate artifacts constantly: reports, images, datasets, analysis results, and intermediate files.

Traditional object storage like S3 can store these files, but it does not provide workflow context for agents.

OutputLayer adds an agent-native layer on top of storage:

Machine-readable agent contracts that tell agents what to do next
Built-in lifecycle management for generated artifacts
Idempotent uploads designed for retrying agent jobs
Public sharing links with safety controls
Expiration and cleanup for transient artifacts

OutputLayer is not just storage — it is infrastructure for agent-generated outputs.

Pricing

Start free. Pay per upload.

Every account starts with a free trial: 5 uploads and 250 MB of storage — no payment required. After that, 1 upload = 1 credit. Credits start at ~3.5¢ per upload. No subscriptions — pay only for what you use.

Persist generated outputs up to 25 MB and retrieve them by ID or public URL.

Pack Uploads Storage Price

Basic 200 + 2 GB $6.99~3.5¢ each

Pro 600 + 10 GB $16.99~2.8¢ each

Agency 2,000 + 50 GB $44.99~2.2¢ each

Credits never expire. Storage is pooled across your account. Purchase via POST /v1/credits/checkout.

Quick Example

Register and upload in two requests

No SDKs. No framework lock-in. Just HTTP.

# 1. Register an API key (no auth required)
curl -X POST https://api.outputlayer.dev/v1/keys/register \
  -H "Content-Type: application/json" \
  -d '{"email": "agent@example.com"}'

# Response: { "apiKey": "ol_live_...", "accountId": "key_01JXXXXX" }

# 2. Upload an artifact
curl -X POST https://api.outputlayer.dev/v1/outputs \
  -H "Authorization: Bearer ol_live_..." \
  -H "Idempotency-Key: job-001-attempt-1" \
  -F "mimeType=application/pdf" \
  -F "label=report" \
  -F "content=@report.pdf"

# Response includes outputId, status, contentUrl, and agent_contract

agent_contract

Machine-readable next-action guidance

Every OutputLayer response — success and error — includes an agent_contract field. Agents read next_actions[recommended=true].action to determine the next step, with no message parsing and no status code switching required.

content_accessible true when content can be downloaded

safe_to_share true when a public CDN URL is available

retryable true for transient failures — same key, retry

expires_in_seconds seconds until content expires, or null

next_actions[ ] 11 stable action codes — exactly one marked recommended
