Analyzing all transaction data for December x402, nearly 60% were used for practical purposes rather than speculation.

We analyzed all x402 transaction data for December 2025:
- 63 million payments
- $7.5 million USDC
- Over 1,100 projects participating
This is the first real-world case proving AI agents can pay for services at scale.
Here are our findings

A Quick History Recap:
The HTTP 402 "Payment Required" status code was defined in 1997 but was never practically implemented.
The reason is simple: credit cards charge $0.30 to process a $0.01 payment, a fee of 3000%. Micropayments were doomed from the start.
Until stablecoins came along and changed everything.
December 2025 Data Snapshot:
- 63 million transactions
- $7.5 million USDC in circulation
- 64,000 unique buyers
- 10,000 unique sellers
- Average transaction amount only $0.12
For comparison: Visa's minimum viable transaction is around $15, while x402 is processing payments 100 times smaller and operating at scale.
The ecosystem is exploding:
- Over 1,100 unique projects
- Over 4,800 mainnet endpoints
- 6 active payment coordinators
Most service providers are small, with no clear dominant player.
Translation: It's a land grab right now.
76% of services charge $0.10 or less
The sweet spot? $0.01-$0.10, accounting for 69% of all services.
This is the micropayments zone—where credit cards can't compete at all.
AI agents optimize for efficiency; they pay on-demand, always per-use.
So what are people actually building?
🥇 Data Services: 31%
🥈 AI/Large Language Models (LLMs): 25%
🥉 Blockchain: 15%
Not memes, not speculative projects.
Real infrastructure: APIs, analytics, inference services.
"Real money" is flowing in.
Base vs Solana—who's winning?
- Base: 53% (the main hub for developers)
- Solana: 37% (the go-to for production)
Base has the Coinbase ecosystem, Solana has speed.
Which one? Depends on your use case.
"Isn't this all wash trading?"
Let's be real:
Artemis data shows 47% of transaction volume is for leaderboard farming.
But—that's only 14% of the total transaction value.
Smaller transactions = cleaner money flow.
Micropayments have been validated.
The unsolved billion-dollar question:
What happens when AI agents pay incorrectly?
x402 has solved "how AI agents pay."
But it hasn't solved:
- Agent identity verification (KYA, Know Your Agent)
- Reputation systems
- Dispute resolution
Whoever solves these will be the ultimate winner.
- 63 million transactions in a single month
- Average transaction value: $0.12
The protocol works.
The economics work.
The developers are here.
The only question left: What will you build on top of it?
