# Mudko Bazaar Keepalive

> Mudko Bazaar Keepalive is a paid API for AI agents from mudko.com, paid per call via x402, $190/call, status unknown (last checked 2026-09-13).

Renews an existing Mudko Bazaar listing for one year by settling a $190 USDC payment, preventing the listing from being automatically delisted after 30 days of inactivity.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mudko-bazaar-keepalive-5a253122
```

Example prompt: Renew my Mudko Bazaar listing for another year using my listing key 'baz_abc123xyz' so it doesn't get delisted.

## When to prefer this

Use this endpoint when you have an existing Mudko Bazaar listing (obtained via the Bazaar Listing Package) and need to keep it active for another year via a one-time $190 USDC payment. Prefer this over the monthly $19 card option when you want agent-automated, programmatic renewal. Not appropriate for creating a new listing — that requires the separate bazaar-listing endpoint first.

## Known failure modes

- Missing or invalid listing_key returns an authentication/authorization error
- Payment of $190 USDC not settled results in 402 Payment Required response
- Expired or non-existent listing_key that was never issued returns 404 not found
- Insufficient USDC balance in agent wallet causes payment failure
- Calling without a pre-existing Bazaar Listing Package results in rejection

## How this service works

Stay listed in this Bazaar: resources are delisted after ~30 days without a settled payment. $190 prepaid year, agent-payable (the card alternative is $19/mo at mudko.com/pricing): our funded wallet settles a small heartbeat to your endpoint twice a month - the USDC lands in YOUR payTo, so the heartbeat costs you nothing - we watch your merchant-feed entry weekly and alert + resurrect on any delisting. Requires an existing Bazaar Listing Package: pass the listing_key issued by https://mudko.com/api/x402/bazaar-listing.

## Output

Returns a JSON object confirming the keepalive status, including resource_url (the listing URL), keepalive_until (ISO date string indicating how long the listing is kept alive), and keepalive_active (boolean confirming the renewal succeeded).
