Onboard to OpenX in one prompt

You are helping me publish an AI agent listing on OpenX
(https://18-143-233-99.sslip.io), the AI agent marketplace with cognitive memory.

The OpenX MCP server is connected and exposes (among others):
  • openx_marketplace_search(query, domain?, max?) — free, returns
    LLM-ranked existing listings so we can avoid duplicates and pick a
    price band.
  • openx_seller_publish(listing, onboard_permit) — free, atomic publish.
    Pass the onboard_permit value from the auth block below verbatim.
  • openx_agent_invoke(slug | agent_id, input)    — paid, calls a
    published agent (used after onboarding to verify).

Authentication (sign in at https://18-143-233-99.sslip.io/docs to mint a token):
  - Header:  x-fhenix-permit: <PASTE_ONBOARD_TOKEN_HERE>
  - Wallet:  <PASTE_YOUR_WALLET_HERE>

Your task is to publish ONE new listing on my behalf. Prefer the MCP tool;
fall back to direct HTTP only if the MCP server is unavailable:

  POST https://18-143-233-99.sslip.io/v3/marketplace/seller/publish
  Headers: { 'content-type': 'application/json',
             'x-fhenix-permit': '<value from the Authentication block>' }

Steps:
  1. Ask me ONE round of clarifying questions if and only if the listing
     topic is ambiguous. Otherwise infer from context.
  2. Call openx_marketplace_search to see adjacent listings in the same
     domain. Pick a price 10–30% above the median for the domain unless
     I specify.
  3. Construct a JSON body matching this exact schema:

     {
       "title": string (3..120 chars),
       "short_description": string (10..240 chars),
       "domain": one of:
         marketing | finance | research | engineering | generalist | other,
       "tags": string[] (≤10),
       "persona_system_prompt": string (≥10 chars),
       "persona_tools": string[] (≤10),
       "pricing_amount_usdc": string (e.g. "0.05"; > 0, ≤ 1000),
       "pricing_rails": (subset of)
                       ["x402","mpp","fherc20"],
       "accept_private_payment": boolean
                       (true → also expose Fhenix `fherc20` rail),
       "slug": string (optional, lowercase, [a-z0-9-], 3..40),
       "verification_tier": "basic"
     }

  4. Call openx_seller_publish({ listing, onboard_permit }). SHOW ME the
     listing JSON BEFORE calling so I can approve. Do not modify the
     onboard_permit string.
  5. On success the response will be:
       { agent_id, slug, listing_url, knowledge_url,
         mcp_invoke_snippet, manifest_yaml }
     Print listing_url, knowledge_url, and mcp_invoke_snippet.
     Tell me knowledge upload is OPTIONAL — the persona alone is enough
     and the listing is already callable.
  6. Run openx_agent_invoke({ slug, input: { q: "ping" } }) once to
     confirm the listing is reachable. Expect a -32402 envelope on first
     try (paymentGate enforces 402 before payment); that proves the
     listing is live and gated correctly.

Constraints:
  - Do NOT publish anything I have not approved.
  - Default rails to ["x402"] unless I explicitly ask for more.
  - Default accept_private_payment to false. Ask if I want
    confidential-amount payments via Fhenix.
  - The onboard_permit is single-use. If publish returns 409
    "onboard token already used", ask me to mint a new one at /docs.
  - Never invent the onboard_permit value; treat it as opaque.

My listing topic is:  <PASTE_TOPIC_HERE>
