Three specialized AI agents — code analysis, context compression, and chat teleportation — available via REST API, Python SDK, and Claude MCP.
Each agent runs on the Fetch.ai decentralized network with a REST API and crypto-native billing.

# 1. Get a free API key (50 requests/day included) curl -X POST https://agentslab.duckdns.org/register \ -H "Content-Type: application/json" \ -d '{"name":"my-project"}' # → {"api_key":"fak_xxx","free_requests_per_day":50,...} # 2.

Add to your .mcp.json,
restart Claude — all 8 tools appear automatically. No SSH keys, no tunnels, no VM access required.
Start free. Subscribe for predictable monthly costs. Or pay per request — whatever fits your workflow.
Pay with a credit card or crypto. Balance is credited instantly (card) or after 1 on-chain confirmation (crypto) — never expires.
One-click Polar Checkout. Balance credited the moment payment completes. No crypto wallet needed.
13 currencies accepted. Send to a generated address — balance credited automatically after 1 on-chain confirmation. No account required.
Call POST /topup with the amount and your preferred currency. You'll receive a unique deposit address for this payment.
Send the exact amount from any wallet. The address is valid for 60 minutes. Each invoice is single-use.
After 1 on-chain confirmation (~10 min for BTC, ~30 sec for BNB/TRX), USD credit is added to your account. No action needed.
Use GET /topup/{invoice_id} to poll. Returns pending → confirming → paid.
# Option A: card payment (instant) — returns Polar checkout URL curl -X POST https://agentslab.duckdns.org/code/topup/card \ -H "X-API-Key: fak_xxx" \ -H "Content-Type: application/json" \ -d '{"amount_usd": 25}' # → {"checkout_url": "https://checkout.polar.sh/...", "amount_usd": 25} # Open checkout_url in browser to pay — balance credited on completion # Option B: crypto invoice — choose any currency curl -X POST https://agentslab.duckdns.org/code/topup \ -H "X-API-Key: fak_xxx" \ -H "Content-Type: application/json" \ -d '{"amount_usd": 10, "currency": "bnb"}' # Check crypto invoice status curl https://agentslab.duckdns.org/code/topup/inv_abc123 \ -H "X-API-Key: fak_xxx" # → {"status":"paid","credited_fet":25.0}
Connect all 3 agents to Claude as native tools. Works in Claude.ai, Cursor, and any MCP-compatible client.
Click "Get Free API Key" above or run POST /register. Instant, no signup.
mcp_server.pySingle Python file. Requires Python 3.9+ and httpx.
curl -O https://agentslab.duckdns.org/mcp_server.py pip install httpx mcp
.mcp.jsonPaste the config with your key. Restart Claude. Done — all 8 tools appear.
"Slim this file for my task", "compress this context", "search my chat history for X" — it calls the agents automatically.
