Ideal buyer

Multi-agent orchestration systems that need to validate workflow topology before execution.

Use with AXON

Run this through your governed agent wallet.

  1. 01
    Bootstrap AXON once with npx @axon402/init.
  2. 02
    Use the AXON runtime MCP tools to search_x402_services or inspect_x402_offer for this service.
  3. 03
    Quote, test-buy, then run the governed paid fetch through AXON.

Send this

Prompt for your agent

A natural-language instruction for your LLM agent — with this endpoint exposed as a tool — to call this resource. Not sent to the endpoint; the endpoint consumes the JSON body below.

Pasting this prompt into a raw ChatGPT or unconfigured agent will notexecute the paid endpoint flow. Run it through an agent with the AXON runtime / MCP tools exposed (see “Use with AXON” above) so the 402 challenge, quote, and governed fetch are handled for you.

“Validate this hop from agent A to agent B with job ID xyz-123 and cost $0.05”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "job_id": "xyz-123",
  "cost_usd": 0.05,
  "to_agent": "agent-b",
  "from_agent": "agent-a"
}

Advanced HTTP details

For integrators who need the raw protocol surface. Most agents should use AXON above instead of calling these directly.

curl fallback

curl https://loopwall.melis.ai/hop \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: [signed_payment_envelope]" \
  -d '{"job_id":"xyz-123","cost_usd":0.05,"to_agent":"agent-b","from_agent":"agent-a"}'

Payment & settlement details

Raw on-chain settlement parameters. AXON above handles these automatically through quote / test-buy / governed fetch.
