I crawled all 31,620 x402 Bazaar listings: most have one payer, and boring chain reads win

On 2026-10-13, a reporter analyzed the entirety of the Coinbase x402 Bazaar, compiling a list of 31,620 unique resource URLs across 2,280 hosts. The majority of these listings featured a single payer, with only 1.3% reaching ten or more payers in a 30-day period. The Bazaar only lists routes after a payment has settled through the CDP facilitator, suggesting that the sole payer behind most listings is likely the seller's test call.

The categorization of resources by keyword in their URL and description revealed that chain data and RPC services had the highest mean payers (4.01) and the largest share of resources with 10+ payers (2.1%). Novelty keywords, including jokes, facts, and coin flips, accounted for 3,949 resources and 1.4% of listings with ten or more payers. News and social media content, web search, price/markets, LLM/inference, and token risk/safety resources all had fewer than 3% of their listings with 10 or more payers.

The most successful host, api.onesource.io, featured thin wrappers over common blockchain functions (eth_getBalance, eth_blockNumber, balanceOf, and eth_getLogs) priced between $0.001 and $0.008. This host had the highest number of distinct payers per route (200-560) in a 30-day period. Meanwhile, more serious categories like token risk/safety had fewer than two payers on average.

The data suggests that plain chain reads, or simple blockchain functions, outperform more complex or novel offerings. The reporter built a comparable service, Plainchain, offering ten GET endpoints for agents at a very low price per call ($0.000942-$0.002942). This service covers major blockchains (Base, Arbitrum, Ethereum, and Optimism) and provides various utilities such as gas estimates, wallet balances, ERC-20 token data, transaction decoding, and block-hash randomness.

The reporter built and runs this service, making its settlement data publicly available at /stats for validation.
