x402 directories and marketplaces compared
A factual comparison. Every integer has a source URL and an access date. If a directory did not publish a number, the cell says not published.
Last updated: 12 November 2026
How to read this table
x402 directories count different things. One row is a facilitator's endpoint index. Another is a service the operator monitors. Another is an API listing a marketplace has chosen to show. A single leaderboard would hide that. This page puts the published figure next to the URL it came from, and the date that URL was read. Where a site did not publish a figure, the cell says not published.
PayAPI's own pair is not typed into this file. It is the live catalogue phrase, the same one llms.txt prints, and the cell links that file. If you are reading a cached copy, trust the date in the PayAPI row and then re-read llms.txt. Third-party figures were read on 12 November 2026 and will go stale. They are labelled with that access date so a later reader can see the age.
Nothing here ranks one directory above another. The units are listings, facilitator endpoints, probed URLs and paid-delivery checks, and those units are not interchangeable.
What each kind of count is allowed to prove
A CDP discovery total is how many resources the facilitator catalogue API returns. Coinbase's docs say a resource is catalogued when a settlement through that facilitator completes, and that a verify step alone is not enough. It does not prove a third party paid the route and read the body. Onchain Agent Intel republishes a daily snapshot of the same API, so their total on the same day can differ slightly. Both numbers are cited. Neither is a PayAPI number.
agent-tools.cloud probes URLs it has seen from several sources. Their cdp-bazaar column is the set of URLs they attribute to that source, which on 12 November 2026 was much smaller than pagination.total on the CDP API. One figure is a probe's source membership. The other is the facilitator catalogue's own page count. x402scan's own site did not return a listing total on that date, so this page does not invent one. The 15,265 figure is agent-tools.cloud's attribution, cited as such.
x402 List publishes three tiers on its own homepage: listed, payment-ready (a live 402) and FORTE (they paid and the service delivered). That paid tier is the closest public cousin of settlement-verified, and it is still not the same measurement. Different wallets, different routes, different pass rules. This page quotes their integers and does not add them to PayAPI's.
Agentic.Market describes itself as a directory of thousands of x402 services and does not print an integer on the homepage that was read. agent402.tools appears as a host inside the CDP snapshot. A total published by that host, as its own directory, was not found, so the cell says not published and then quotes the host count from the snapshot that does exist.
What PayAPI is claiming, and what it is not
PayAPI Market claims the pair in the first row, on the date that row names, and only when the catalogue read succeeded. Settlement-verified means this operator paid one route and linked the receipt. Listed means the row is in the live catalogue, including imported_unclaimed rows. Free to list, and PayAPI takes 0% of each job, is a pricing statement, not a size statement.
If a figure here is wrong, the source URL and the access date say what was read. This page will not swap in an unsourced number.
The narrative version, without this table, remains x402 Bazaar and Agentic.Market alternatives.
The comparison
| Directory | What it publishes | Listed count | Paid-call check | How an agent reads it |
|---|---|---|---|---|
| PayAPI Market | A catalogue of x402 APIs plus a separate agent marketplace. Discovery is free over MCP and HTTP. Buyers pay the provider. Listing is free, and PayAPI takes 0% of each job. | 1,559 settlement-verified APIs, 2,755 listed. Listings include rows imported from public directories (imported_unclaimed) unless a caller asks to leave them out. Source: https://payapi.market/llms.txt.

Frequently asked questions
Which x402 marketplace lists the most APIs?
This page does not answer that with a ranking. The CDP discovery API reported pagination.total of 34,070 on 12 November 2026, at https://api.cdp.coinbase.com/platform/v2/x402/discovery/resources?limit=20. PayAPI's listed total is the live catalogue figure in the table, from https://payapi.market/llms.txt. The units differ, so the page does not treat either number as a winner.
Did PayAPI pay for every API it lists?
No. Settlement-verified means PayAPI paid one route on that listing and published the receipt. Other listings are in the catalogue, including imported_unclaimed rows, without that receipt. The rule is at https://payapi.market/how-we-verify.
Why does the CDP total disagree with agent-tools.cloud?
They count different cuts. On 12 November 2026 the CDP API pagination.total was 34,070. agent-tools.cloud, at https://agent-tools.cloud/stats/x402 as of 2026-11-12 06:46 UTC, attributed 4,492 listings to a source it calls cdp-bazaar and indexed 24,531 x402 APIs overall. Those are probe memberships, not the facilitator catalogue's own page count.
What is x402 List's verified count?
x402 List's own page, https://x402-list.com/, last updated 2026-11-12, said 1,305 listed services, 1,237 payment-ready, and 13 in the FORTE tier where x402 List paid a call and the service delivered. That tier is not PayAPI's settlement-verified badge.
Where is Agentic.Market's listing total?
not published as an integer. https://www.agentic.market/ said "Thousands of services" when read on 12 November 2026. The Coinbase launch post describes it as the directory on top of the CDP Bazaar, indexed when the CDP Facilitator settles a payment.
