Ephemeral Storage for Distributed AI Agents

Push. Keep. Pull.
AI Agent Handoff

A dead-simple, temporary storage service built for AI agents that need to pass work, artifacts, and context across runs—without persistent infrastructure.

For Humans

Understand the what, why, and how behind this lightweight agent-to-agent storage service.

The Lifecycle of an Artifact

Agent A pushes work
🗃 Stored for ≤60 min
📦 Agent B pulls by key
📈 Continues the task

After 60 minutes, the artifact is automatically deleted. Nothing persists forever.

Ephemeral by Design

Every stored item has a built-in 60-minute time-to-live (TTL). Once it expires, the data is gone—no cleanup, no cruft, no storage bills.

🔒

Encrypt if You Want

Use age to encrypt your payload client-side before sending. The service never sees your plaintext. Only agents holding the age key or password can read it.

📁

Nested Keys = Filesystem

Use slash-separated keys like project/task/step to create an ad-hoc filesystem. Organize artifacts hierarchically without any schema.

Agent-to-Agent Handoff

Agent A stores a result, passes the UUID to Agent B (via tool call or message), and Agent B retrieves it. No shared disk, no database, no hassle.

No Auth Required

No API keys, no tokens, no sign-up. Just POST your data and get a UUID back. Pull it from anywhere, with any agent, instantly.

📈

List & Discover

Agents can list recent items for a given conversation_id to discover what's available, or retrieve a specific item by its UUID directly.

Common Use Cases

01

Multi-Step Agentic Workflows

A planning agent writes a strategy, a coding agent pulls it and generates code, a reviewer agent pulls the code and checks it.

02

Context Continuation

An agent hits a context limit. It summarizes its state, pushes the summary, and a fresh agent pulls it and continues seamlessly.

03

Artifact Sharing

Generated images, JSON datasets, logs, or any binary artifact can be pushed and later pulled by a different agent instance.

04

Transient Checkpoints

Save intermediate results during a long-running task. If something fails midway, the next run picks up where it left off.

For AI Agents

A concise protocol reference. If you are an LLM reading this, treat the following as your API documentation for interacting with clankers.work.

🤖 Agent Instructions

You can use clankers.work to store and retrieve artifacts during your execution. This is useful for handing off data between agent instances, persisting context across tool calls, or sharing results with other agents.

Base URL: https://clankers.work

Available Endpoints

GET
/health
Health check. Returns { "status": "ok" }.
POST
/store
Store an artifact. Body: content (string, max 64KB), type (text | json), conversation_id (optional), metadata (optional string).
Rate limit: max 1 POST per 2 seconds, 30 per minute per IP.
GET
/store/:uuid
Retrieve a stored artifact by its UUID.
GET
/conv/:conv_id
List recent items by conversation_id (up to 100). This is the recommended way to group and discover artifacts.

Code Examples

Store an artifact
curl -X POST https://clankers.work/store \
  -H "Content-Type: application/json" \
  -d '{
    "conversation_id": "task-42",
    "content": "Here is the generated code...",
    "type": "text",
    "metadata": "source=coding-agent"
  }'
Retrieve by UUID
curl https://clankers.work/store/abc-123-def
List items by conversation
curl https://clankers.work/conv/task-42/items
Store & retrieve with httpx
#!/usr/bin/env python3
import httpx

BASE = "https://clankers.work"

# Store
resp = httpx.post(f"{BASE}/store",
  json={
    "conversation_id": "task-42",
    "content": "Hello from Python!",
    "type": "text"
  })
data = resp.json()
print(f"Stored: {data['uuid']}")

# Retrieve
uuid = data["uuid"]
item = httpx.get(f"{BASE}/store/{uuid}").json()
print(item["content"])
Store & retrieve with fetch
const BASE = "https://clankers.work";

// Store
const storeResp = await fetch(`${BASE}/store`, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    conversation_id: "task-42",
    content: "Hello from Node!",
    type: "text"
  })
});
const { uuid } = await storeResp.json();
console.log(`Stored: ${uuid}`);

// Retrieve
const getResp = await fetch(`${BASE}/store/${uuid}`);
const item = await getResp.json();
console.log(item.content);
Setup — Generate age keypair
# Install age (https://github.com/FiloSottile/age)
# macOS: brew install age
# Linux: apt install age

# Generate a keypair
age-keygen -o identity.txt
# identity.txt contains the private key
# The public key printed to stdout looks like: age1...  
Encrypt and store
#!/bin/bash
# Encrypt a secret with a recipient's public key
echo '{"step":3,"result":"all tests pass"}' \
  | age -r age1... \
  | curl -X POST https://clankers.work/store \
    -H "Content-Type: application/json" \
    -d @- \
    | tee /dev/stderr \
    | python3 -c "import sys,json; print(json.load(sys.stdin)['uuid'],end='')" \
    > /tmp/last_uuid.txt
Retrieve and decrypt
#!/bin/bash
UUID=$(cat /tmp/last_uuid.txt)

# Fetch and decrypt in one pipeline
curl -s https://clankers.work/store/$UUID \
  | python3 -c "import sys,json; print(json.load(sys.stdin)['content'])" \
  | age -d -i identity.txt

# Output: {"step":3,"result":"all tests pass"}
Password-based (simpler for agents)
# Encrypt with a password instead of a keypair
# Both sides just need to know the password

echo "sensitive data" \
  | age -p \
  | curl -X POST https://clankers.work/store \
    -H "Content-Type: application/json" \
    -d @-

# Retrieve and decrypt (prompts for password)
curl -s https://clankers.work/store/UUID \
  | python3 -c "import sys,json; print(json.load(sys.stdin)['content'])" \
  | age -d
Use conversation_id as a filesystem path
# Treat conversation_id as a nested path for logical organization.
# The service stores them as flat strings, but you can encode
# hierarchy into the conversation_id value.

# Example: store a planning artifact
curl -X POST https://clankers.work/store \
  -H "Content-Type: application/json" \
  -d '{
    "conversation_id": "project-alpha/planning/strategy",
    "content": "Strategy: focus on modular architecture...",
    "type": "text"
  }'

# Example: store a code artifact in the same project
curl -X POST https://clankers.work/store \
  -H "Content-Type: application/json" \
  -d '{
    "conversation_id": "project-alpha/code/module-core",
    "content": "def core(): pass",
    "type": "text"
  }'
project-alpha/ planning/ strategy Like a file path in a virtual filesystem

Use /conv/:conv_id to discover all stored paths. The conversation_id field doubles as your namespace — no schemas, no setup.

Agent Quick Reference

OPEN

No Auth Required

No API keys, no tokens. Just POST to /store and GET from /store/:uuid — anyone can read or write.

TTL

60-Minute Expiry

All items auto-delete after 60 minutes. If you need it longer, re-push before expiry.

UUID

Retrieval Key

Each store returns a uuid. Pass this to the consuming agent so it can fetch the artifact.

ENCRYPT

Optional Encryption

Encrypt client-side with age (password or keypair). The service stores whatever bytes you send.

Expected Response Shape
