A complete census of the Coinbase Bazaar x402 catalogue, measured 2026-08-03. Not a sample — 14,696 resources, paginated to exhaustion, matching the total the API reports for itself.
Median price: $0.0100
Across 18,649 priced USDC entries (after screening) from 986
distinct seller addresses. The catalogue holds 1,244 distinct payTo
addresses in total — 987 of them carry a USD-denominated price, and 986 of those survive the screen
below. Those three numbers are different populations and are kept apart deliberately.

| $10+ | 56 | 0.3% |
45.5% of every priced x402 entry is between $0.001 and $0.01. Only 1.9% is priced at $1 or above. If you are pricing above a dollar you are not competing in this market, you are next to it — which may be correct, but it should be a decision rather than an accident.
Hosts with at least 20 priced entries. The count column matters: one operator can dominate any per-resource average.

A catalogue entry is a listing, not a promise. We probed 400 hosts, one endpoint each, one unpaid request per host — a live x402 resource answers 402, which is its advertised contract.
| result | hosts | share |
|---|---|---|
| live — answers 402 as advertised | 378 | 94.5% |
| reachable, other response | 12 | 3.0% |
| answered without payment | 8 | 2.0% |
| 5xx | 1 | 0.2% |
| unreachable (404 on both verbs) | 1 | 0.2% |
The catalogue is in far better health than we expected: 0.2% unreachable (±0.5pp, 95% CI, n=400 hosts). We went looking for rot because our own listing advertised a retired route for 16 days — but that rot was in the directories, not in the endpoints.
A warning worth more than the number, because it nearly became our headline.
Our first pass probed with GET only and reported 11.2% unreachable.
That figure was wrong by 56x. Most x402 endpoints are POST-only and
answer 404 or 405 to a GET — 87 of the endpoints the
GET-only probe called dead answered 402 the moment they were asked with POST.
Our own routes behave exactly this way: /scan/secrets returns 404 to GET and 402 to
POST. So the probe would have declared our own live, paid endpoints dead.
If you are auditing x402 liveness, probe both verbs before calling anything dead. A single-verb sweep will tell you this market is decaying. It is not; your probe is.
The audience for this is mostly agents, and agents do not read tables. Everything above is also
at /x402-pricing.json — percentiles, bands, the
liveness result with its method warning, and per-host medians and percentiles for all 1,387 hosts.
CC0, no signup, no payment, CORS open, so an agent can fetch it cross-origin and
price itself without asking anyone.

limit=1000, offset paging until short page. 15 pages, 14,696 records.accepts[] whose extra.name contains USD; price is
amount / 1e6.0 < price ≤ $1000. The raw feed
contains an entry parsing to $250,000,000,000. Percentiles survive that; means
and maxima do not. This screen drops 165 of 18,814 entries.Two denominators, deliberately not blurred. The catalogue holds 1,519 distinct hosts across all 14,696 resources, but only 1,387 of them have a priced USDC entry — those are the ones the lookup can answer for. A host absent from the lookup is not necessarily absent from x402; it may price in another asset, or carry no parseable price at all.
What this does not establish. These are advertised prices, not revenue. Nothing here says anyone paid them. Our own listed endpoints earn on the order of $0.007 per month, and roughly 70% of the requests that do arrive are one catalogue crawler rather than buyers. Treat this as the shape of supply.
The census is a single day's snapshot of a catalogue that was growing while we read it. Any figure quoted from this page should carry 2026-08-03 beside it.
