x402 Bazaar Census

A dated, reproducible enumeration of the public x402 Bazaar discovery index — the catalogue autonomous agents search to find services they can pay for over HTTP 402.

As far as we can establish, nobody has published a measurement of this index before.

What the index looks like

Prices (USDC)

Zero-priced entries are counted separately and excluded from these figures — a zero is a free seed route, not a price.

Networks

Concentration

The three most frequent payee addresses account for 63.7% of all accepts entries.

Busiest hosts

Series

This is a dated series, not a one-off. The full corpus (items.jsonl) is published once as the reference; each later run adds a summary and a delta, so the index can be tracked without republishing 25MB a day.

2026-09-04 → 2026-09-05

Growth counts declarations, not working services or revenue. A resource enters this index by being catalogued off a settled payment; it does not follow that the resource works, settles again, or has any customers. snapshots/ holds each dated summary.

Method

Keyless paginated HTTPS GET against https://facilitator.payai.network/discovery/resources, limit=1000, 0.4s between pages. No authentication is required — the endpoint is the public discovery surface of a public facilitator. items.jsonl is the raw response rows, one per line, key-sorted. census.json carries the derived figures and their own sha256.

What this is not

A DISCOVERED listing is not a grade. This census counts what the index publishes; it says nothing about service quality, honesty, solvency or fitness of any listed resource. Not a ranking. Not an endorsement. Never a certificate.

Explicitly unmeasured here, and stated rather than implied:

• service quality
• uptime
• honesty of any listed resource
• whether a listed resource settles
• duplicate detection across hosts
• whether resources declare a bazaar schema (the LIST response carries no extensions object for any row; that is a property of this endpoint output, not proof the resources lack one)

A listing in this index means a resource declared itself. It does not mean the resource works, settles, is honest, or is solvent. Several hosts in the data are ephemeral tunnels.

Reproducing it

Every figure comes from the two files in this repo. Re-run the same paginated GET and diff items.jsonl; the index moves, so a later run should differ, and that difference is the point.

Dual-index census (2026-09-05)

dual-index/overlap-2026-09-05.json

There is not one x402 Bazaar. There are at least two public discovery indexes, and they are close to disjoint. Both were read in full — paged to exhaustion, not sampled.

• resources in both: 1,698
• only in CDP: 14,526 · only in PayAI: 26,496
• hosts in both: 110 of 3,454 (3.18%)

Why it matters. "Listed in the x402 Bazaar" is not a single fact — it is one fact per index. A seller listed in one is not discoverable in the other, and 96.8% of hosts are in exactly one. Neither index exposes a registration endpoint: a resource is catalogued off a confirmed settle, so appearing in CDP's index requires settling through CDP's facilitator, which needs credentials.

This is a census of two public catalogues. It scores nobody, ranks nobody, and enters no board cell. Measurement, not certification.

The live board is the authority

GET https://councilof.ai/api/gspc — quote totals.public_count. This Hub card is a printer of that GET, never a second engine. If the fetch fails the honest answer is UNCHECKABLE — never a fabricated 0.000. Status words: LOADING / UNREACHABLE / UNMEASURED / UNCHECKABLE.

What is in this repository

manifest.jsonl is derived from this repository's own file tree at 2026-09-05T12:52:39Z; it lists every file with its size, its blob hash and a direct URL, so an agent can enumerate the repo without cloning it.
