Audit of 1,000 x402 endpoints: 207 never quoted a price

A scan of Coinbase's x402 Bazaar directory found that 768 of 1,000 paid endpoints returned 402 with machine-readable requirements, while 207 never returned 402 at all (106 × 404, 78 × 405). Only 55 of the 768 (7.2%) publish an outputSchema, and 64 use legacy network strings instead of CAIP-2.
