The raw numbers

I pulled the last 15 days of CDP facilitator settlements off Base mainnet. The facilitator wallet at 0x8f5cb67b49555e614892b7233cfddebfb746e531 has been the dominant x402 settlement path since late 2025, so sweeping its transferWithAuthorization calls gives you a defensible lower bound on activity.

Between May 1 and May 15, 2026:

  • 2.71M total x402-paid calls settled on Base
  • $171,400 USDC routed through the CDP facilitator
  • Average payment size: $0.063
  • 47,300 distinct payer wallets (de-duped by address, not by likely operator)
  • Daily call count climbed from 142k on May 1 to 218k on May 15

And the 7-day moving average is up about 38% month over month. The first 200k day landed on May 12.

For context: in November 2025 the same metric was averaging 9k calls per day. We're roughly 20x in six months.

Top 10 endpoints by call volume

Ranked by settled calls over May 1-15. Numbers are settled-call counts on-chain, not unique callers.

1. coinbase/x402-bin ($0.001 test endpoint): 412k calls 2. agentutility/satellite-tile ($0.002 to $0.04 by zoom): 287k calls, $9,840 settled 3. weatherbase/forecast-1h ($0.005): 241k calls 4. agentutility/secrets-exposure-check ($0.01): 198k calls 5. lookuplab/ens-resolve ($0.002): 187k calls 6. agentutility/brand-clearance-domain ($0.03): 142k calls 7. agentutility/satellite-bbox ($0.05): 118k calls 8. ipdata/geo-lookup ($0.002): 96k calls 9. agentutility/trademark-search ($0.04): 81k calls 10. rpc402/eth-rpc ($0.0005): 78k calls

A few things jump out. Coinbase's x402-bin still tops the list because half the directory points smoke tests at it. Strip that out and the chart shifts. Satellite-tile is the highest-revenue endpoint in the top 10 by a wide margin, partly because zoom 18 calls bill at $0.04 and there's been steady demand from a couple of map-overlay agents through May.

Where agentutility lands

Five of the top ten endpoints by call count are ours. By calls, the portfolio captured 826k of the 2.71M paid calls in the period, about 30.5%. By USDC settled across all 2.71M calls, the portfolio's share is closer to 14-15%, because the long tail of mid-priced specialty endpoints (most of them not ours, yet) is where most of the dollar volume sits.

But the top 10 by calls only account for $27k of the $171k total. The other $144k is spread across a few hundred specialty endpoints clearing 1k-30k calls each at prices between $0.05 and $1. That tail is where the directory's actual revenue lives.

What the trajectory says about pricing

Two things are happening at once.

The floor is dropping. RPC providers, ENS lookups, basic geo data, simple price feeds. Anything already commodity off-chain is settling at fractions of a cent on-chain too. rpc402/eth-rpc at $0.0005 per call isn't sustainable for anyone but the operator who already had the RPC infrastructure paid for. But new entrants in that band will lose money.

The middle is widening. The $0.01 to $0.10 band is where agents actually pay for something they can't assemble cheaply: a clean trademark hit, a satellite tile at usable zoom, a structured CVE lookup, a verified webhook signature. That band's average price per call climbed from about $0.014 in November to $0.041 in May. Higher floor, more headroom.

So the playbook for new endpoints is: don't try to win on cents-per-call against an incumbent who already runs the infrastructure. Win on a thing the agent needs that's annoying to assemble. Then charge accordingly.

What about the $1+ band? Still mostly empty. A handful of legal-research and image-generation endpoints are testing dollar pricing and the call counts are small. Either the agents calling x402 in May 2026 don't have the budget yet, or they're routing dollar-class work somewhere else entirely.

Worth watching as the next directory wave rolls in.
