Reputation 19/100, 24% citation rate. Cached. Preview explicitly mentions Coinbase corporate customers accepting payments from AI agents via x402 protocol. Highly relevant to subclaims 1 and 3.
Reputation 5/100, 19% citation rate. Cached. Preview directly mentions Cloudflare introducing wallets for AI agents and plans for stablecoin payments, highly relevant to subclaims 1 and 2.
Reputation 8/100, 14% citation rate. Not cached. Preview mentions AI economy mapping using Stripe data, which could provide valuable context on demand patterns and growth for the machine-to-machine economy (subclaim 3). Price is low ($0.002).
Reputation 5/100, 16% citation rate. Cached. MetaMask AI wallet for autonomous trading is relevant to agent commerce (subclaim 3) but more about trading than x402 payment protocol specifically.
High reputation (37/100) and 49% citation rate on this subject. Cached, so free. Directly covers stablecoins as the unit of account for agents, crucial for subclaims 2 and 3. — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Reputation 5/100, 11% citation rate. Cached. Focuses on AI agents in Ethereum protocol code, which is tangentially relevant to agent commerce but not directly about x402 or stablecoins. Likely low direct value for this specific question. — cached bytes are free, but this read does not clear the attention gate (EV 0.60, minimum 0.45, with a required claim target).
Reputation 16/100, 23% citation rate. Cached. Benchmarks on x402 settlement latency on Arc directly relevant to protocol performance (subclaim 1). — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Reputation 20/100, 29% citation rate. Cached, free. Explicitly covers x402 as a payment rail for agents, directly supporting subclaim 1. — the 4-source attention budget is full, so lower-ranked evidence is skipped.
Reputation 4/100, 14% citation rate. Cached. General payment timing, less specific than Arc benchmarks already cached. Redundant with higher-value source.
Low citation rate (14%) and reputation (4/100). Technical focus on idempotency keys is peripheral to the main x402+stablecoins commerce narrative. Cached but skip.
Zero citation rate. Regulatory approval in Netherlands is not about x402, stablecoins for agents, or agent commerce. Cached but skip.

The sources mention x402 and stablecoin use for AI agent payments, but do not provide the detailed protocol descriptions or economic concepts claimed. Coverage of the sub-claims is therefore low.

Final coverage assessment — The gathered sources mention x402 and stablecoins separately but do not provide detailed definitions of x402 or explicitly demonstrate how they combine to enable autonomous microtransactions without human approval. Coverage is insufficient to support the sub-claims.
