The x402 "agent economy" has 24,000 sellers and almost no buyers

x402 (HTTP-402 stablecoin micropayments for AI agents) is pitched as a booming machine economy. I pulled the hard numbers from public endpoints.

Method (reproducible): fetched Coinbase's CDP facilitator /discovery/resources (the x402 Bazaar catalog), sampled 700 of the 24,488 listed resources, and checked the top sellers' on-chain USDC activity on Base via a public explorer.

Findings:

• 24,488 listed endpoints, but a 700 sample had only ~106 unique payout addresses — a few operators spam hundreds of listings each.
• Median price ~$0.005/call; 77% priced $0.001–$0.01.
• On-chain, the long tail earns ≈ $0: independent multi-listing sellers held $0–$3 USDC with a few hundred lifetime transfers. Activity is hyper-concentrated — one infra endpoint had ~440k token transfers vs <2k for typical listings.
• The headline (≈$24M/30d, 94k buyers, 22k sellers) masks a per-seller median ≈ $0; volume is concentrated in infra/first-party traffic and (earlier) a pay-to-mint memecoin.

Takeaway: x402's bottleneck is demand/discovery, not supply. Listing an undifferentiated endpoint earns ~nothing. If there's an opportunity it's on the demand/aggregation side, or a differentiated data product you actively drive traffic to — not passive listing.
