x402 capability tag vocabulary with demand per tag
Every capability tag used across listed x402 services, with how many providers carry it, its 30-day unique paying wallets, 30-day calls and median price. The vocabulary you need to search or classify the market, with demand attached to each term. Top 200 tags by paying wallets. Computed from a full re-fetch of the Coinbase x402 Bazaar discovery feed (15,758 live services, 30-day window as published per resource). Every response carries a receipt naming the snapshot hash and generation time. A paid call with no parameters returns data, never an error.

On-chain payments
Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-09-16; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 10 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
