Your x402 API works. Agents just can't find it.
It's often something silent: an http:// resource URL where https:// belongs, an extensions block in the wrong place, a description the Bazaar screens out, or missing OpenAPI fields. The Listing Fix finds it and tells you the exact change.

Listing Fix
For you if you want it done for you, with a written report.
$49 ($29 founding price)
We check one service against the 5 catalogs we cover and send you the exact fixes, in order.
What you get
A written report on one x402 service, up to 5 paid routes, by email from hi@unlisted.sh. The quoted lines come from our sample report.
- Summary: what's wrong, in plain words, and what to do first.Sample: “Both routes are listed and healthy, but a buyer searching in everyday words does not find them.”
- Catalog status, with timestamped evidence: each catalog's listing entry next to your live 402, side by side.Sample: “CDP Bazaar, read 2026-11-02 19:19:47 UTC: /history shows an old description. Neither route has tags or a service name.”
- Fixes in order: the exact change for each, with code snippets in your stack.Sample: “Exact change: set service_name and tags on each paid route's RouteConfig.”
- Description rewrite: search words first (what it is, as a buyer would type it), then a "use when" line, under 500 characters, and your best 5 tags first.Sample: “Crypto news sentiment for one coin: label, score and top 5 headlines. Use when an agent needs a current read on news sentiment for a coin before research or a trade.”
- Trust signals: health, response time, unknown paths returning 404, prices in line with similar services and real paid calls.Sample: “Health endpoint: GET /health returned 200 {"status":"ok"} in 0.24 s (median of 5).”
- Next steps and recheck: what to do after the fixes, and what counts as fixed.Sample: “It counts as fixed when both listings show the new description and 5 tags, and at least one route comes back for "crypto sentiment".”
How it works
- Pay, and tell us your service, its paid route URLs and your stack at checkout.
- We check it read-only: Unlisted's 18 automated checks plus each catalog's listing. If a route needs one, we make one test payment.
- You get the written report within 3 business days.
- You apply the fixes and ask for your free recheck within 30 days.
Catalogs covered
| Catalog | How listing works | What we check |
|---|---|---|
| Coinbase CDP Bazaar | A route is listed after a payment to it settles through CDP's facilitator with a valid extensions.bazaar declaration. Routes with no settlement for 30 days are removed. | Your live 402 next to the listing, CDP's index status, and whether Bazaar search finds you for your own words. |
| Agentic.market | Its cards are pulled from the Bazaar. Whether a card is enriched (description, category, icon) is decided by Coinbase; we never promise it. | Whether your card is there and what it shows. |
| x402scan | Reads your 402s and your OpenAPI spec. You register the service yourself, with a wallet sign-in. | The OpenAPI fields it asks for: price and protocols on each paid route, input and output schemas, and free routes marked public. |
| Circle Agent Marketplace | You apply with an intake form and Circle reviews it by hand. It needs a working 402 and a published OpenAPI spec, checks your service's health continuously and drops it when unreachable. | Your 402, OpenAPI spec and uptime, so your form is ready to submit. |
| x402-list.com | Confirms you own the domain with a token file at /.well-known/x402list.txt. | Whether your service appears and what it shows. |
Is this a fit?
Good fit
- Your x402 endpoint takes payment, but agents can't find it in the catalogs.
- Your payments settle through CDP's facilitator, or you're willing to switch.
- You want the exact changes written out, and you'll make them yourself.
Not a fit
- Your API doesn't use x402 yet.
- Your payments settle through your own or another facilitator and you won't switch. Those never reach the CDP Bazaar, and we'll tell you that for free: payments through a different facilitator.
- You need a guaranteed listing. Each catalog decides on its own.
Already listed?
The Listing Fix also confirms that a listed service is healthy and that buyers can find it, and refreshes stale listing text.
Your safety
We never ask for:
- API keys
- Passwords
- Seed phrases
- Wallet access
- Repository access
- Deploy access
We only read what is public: your 402 responses, your OpenAPI spec and the catalogs. You make every change yourself.

Questions
How fast do I get the report?
Within 3 business days of payment, by email from hi@unlisted.sh.
What if you can't deliver?
You get a full refund, for example if your endpoint is unreachable or isn't x402. Once the report is delivered, the fee covers the work, whatever the catalogs decide.
Do I need to give you access to anything?
No. We never ask for API keys, passwords, wallet access, repository access or deploy access. We only read what is public: your 402 responses, your OpenAPI spec and the catalogs. You make every change yourself.
What's the test payment?
If a route priced up to $0.05 isn't indexed, we may make one real test payment to your endpoint from our own test wallet, so CDP has a settlement to index.
My route costs more than $0.05. What then?
We only make a test payment to it if you ask us to and cover the amount. The rest of the report is the same.
Can my AI agent buy this?
Not the Listing Fix: a human pays for it by card through Stripe, so an agent should hand https://unlisted.sh/fix to its operator. The $0.02 Check is different: an agent can pay for it itself over x402, in USDC on Base, with no signup.
What happens after I pay?
At checkout you tell us your service, its paid route URLs (up to 5) and your stack. We check it read-only and, if needed, make one test payment. You get the written report within 3 business days. Apply the fixes, then ask for your free recheck within 30 days.
What will my card statement show?
Your card statement shows CRYPTO SENTIMENT. Our payment account is shared with our Crypto Sentiment API, also run by Forge Alone.
Terms
What you get: a written report on one x402 service (up to 5 paid routes) covering the agent catalogs it should appear in, the reason it is missing from each, and the exact change to make. Delivered by email from hi@unlisted.sh within 3 business days of payment. One free recheck within 30 days.
No listing guarantee: each catalog (Coinbase CDP Bazaar, x402scan, Circle and others) decides on its own. We diagnose and recommend; you make the changes.
Test payments: if a route priced up to $0.05 isn't indexed, we may make one real test payment to your endpoint from our own test wallet so the catalog has a settlement to index. For routes priced higher, we only pay if you ask us to and cover the amount.
What we never ask for: API keys, passwords, wallet access, repository access or deploy access. We only read what is public: your 402 responses, your OpenAPI spec and the catalogs.
Refunds: full refund if we can't deliver a report (for example, your endpoint is unreachable or isn't x402). Once the report is delivered, the fee covers the work, whatever the catalogs decide.
Privacy: your details and report stay private. We never publish your service or results without your written permission.
