}
}Any MCP-compatible agent
The MCP server auto-discovers all 20 tools from the live catalog at startup. Tools are dynamically loaded — new services appear automatically without updating the server.
How payments work
Each tool call uses the x402 protocol:
Agent calls a tool
Server probes the service (HTTP 402 response with payment requirements)
MCP server signs USDC payment on Base mainnet using your private key
Service executes and returns result
Payments are atomic per call — you only pay when a call succeeds. The wallet needs USDC on Base mainnet.
Get USDC on Base:
Bridge from Ethereum: bridge.base.org
Buy on Coinbase → withdraw to Base
Swap on Uniswap/Aerodrome (Base)
Cost examples
Usage | Daily cost |
100 calls/day (avg $0.003) | $0.30 |
1,000 calls/day | $3.00 |
10,000 calls/day | $30.00 |
REST API
All tools are also available as a direct REST API without MCP:
# Step 1: probe (get payment requirements)
curl -X POST https://agentsvc.io/api/v1/proxy/ip-lookup \
-H "Content-Type: application/json" \
-d '{"ip": "8.8.8.8"}'
# → HTTP 402 with accepts[] payment requirements
# Step 2: sign + retry with X-Payment header
# See: https://agentsvc.io/docsEndpoints:
