x402 Bazaar Market Map

Data as of 2026-09-07T09:00:55Z UTC · refreshed daily by an automated snapshot pipeline (task 0267).

Our snapshot of the public Coinbase CDP x402 Bazaar discovery catalog — cut by CDP’s unique-payer signal, not by raw listing count. 14,689 endpoints indexed from https://api.cdp.coinbase.com/platform/v2/x402/discovery/resources. Snapshot fetched 2026-09-07T09:00:55Z (status: ok; reported catalog total: 14,689).

Headline: only 762 of 14,689 indexed endpoints (5.19%) report ≥5 unique payers in CDP’s own quality signal over the last 30 days. That is the strong-filter cohort — the rest is long tail.

Roughly 99.7% of the catalog reports at least one unique payer in the last 30 days, so a > 0 test is not itself a trust signal. Payer thresholds tighten the cohort in a way a binary present-or-absent cut cannot. Signal source is CDP’s quality.l30DaysUniquePayers, applied verbatim — nothing self-reported, nothing scored by us.

Unique-payer distribution (last 30 days)

Full histogram, exclusive buckets — counts sum to the indexed total. The long tail on the right is the trust cohort; the mass on the left is what makes a bare “> 0 payer” filter meaningless.

Reputation footprint of the earning cohort (Base, snapshot 2026-09-01)

Endpoints that earn money on Base and endpoints that carry an on-chain reputation footprint are almost entirely disjoint. Of the 14,338 Base x402 endpoints in this snapshot that took ≥1 paid call in the last 30 days, 1,291 (9.00%) resolve to a registered ERC-8004 agent owner by exact pay_to → owner match, 9 (0.063% of the earning set; 0.697% of the resolvable subset) carry any on-chain reputation feedback, and 0 carry commerce-backed reputation — feedback backed by a real ERC-8183 job outcome rather than a bare thumbs-up. The same shape at the publisher level: 26 distinct pay_tos, 4 with any feedback (one event each, one unique client apiece), 0 commerce-backed. Every share here is a lower bound (pay_to may be a treasury wallet distinct from the registration owner; we index the ERC-8004 registry on Base and Ethereum only; per-publisher dedup capped at 50 rows so a single bulk-mint publisher cannot flood the resolvable set — disclosing that cap is what makes the resolvable count auditable). Full method and predicate: /how-do-you-know-which-agent-is-safe-to-pay. Dedicated dataset with the publisher-level cut, JSON + CSV: /x402-paid-but-unrated. That gap is where our paid intel lives.

Since previous snapshot

Since previous snapshot at 2026-09-07T08:30:41Z — this delta updates on every daily refresh of the market map.

By network

Which chains the Bazaar catalog settles on. An endpoint can list multiple networks, so the sum can exceed the endpoint count.

By category

Lightweight keyword bucketing from each endpoint's description, service name, URL, and tags. "uncategorized" is anything the keyword rules didn't match.

Price distribution (USDC)

Cheapest USDC-denominated accepts[] entry per endpoint. Non-USDC legs (SPL, Stellar assets, non-stablecoins) don't show up here. Full percentile ladder, histogram, and per-bucket CSV live at /what-does-an-x402-api-call-cost — the canonical price-census answer page.

Most expensive endpoints

Top hosts by endpoint count

Concentration — a small number of hosts publish a large share of the catalog.

Methodology & source

Source: https://api.cdp.coinbase.com/platform/v2/x402/discovery/resources — the public Coinbase CDP x402 Bazaar discovery API. No API key required. On-Chain Agent Intel fetches the full catalog once per day, normalizes each item into a stable record shape (network, scheme, payTo, USDC price, quality signal), and diffs against the previous snapshot to produce the delta panel above. The trust-filter cohort uses only fields CDP itself publishes on the endpoint — nothing self-reported, nothing scored by us.

Why unique payers, not total calls. CDP publishes both quality.l30DaysUniquePayers and quality.l30DaysTotalCalls on every indexed endpoint, and both are non-zero on the same near-universal share of the catalog. This page reports the unique-payer signal because it’s harder to inflate — a single client hammering an endpoint bumps calls without changing the payer count, so payers is the tighter filter for real usage breadth. Both signals come from CDP; neither is de-noised by us.

Snapshot cadence is daily — every fresh build of this page reads the latest fetch. This is a live-updating dataset page, not a one-off report. For the long-form treatment of what this data means for the ERC-8004 / agent-intel corner of the Bazaar, read Report 06 — The x402 Agent-Intelligence Market Map. For the whole-catalog demand-concentration headline as a standalone citable finding, see Report 07 — Only 5.19% of x402 endpoints have ≥5 unique payers in 30 days.

On-Chain Agent Intel is not affiliated with Coinbase. The Bazaar catalog is published by CDP under the URL above; we redistribute a normalized cut of it as a live-updating reference page.
