Essays on AI infrastructure, agent payments, and the right shape for the stack.
Nothing to Steal
The safest way to read a hostile web page is with a reader that has nothing to steal and nothing to hijack.
The wild web is turning hostile to AI agents — recent research tricked six AI browsers into handing over passwords. The fix isn't a smarter guardrail; it's least privilege. Skim is a reader that carries no credentials and takes no actions, so there's nothing for a malicious page to reach for.

The Last Human in the Loop
Why an autonomous agent needs a wallet, not an API key.
An API key is the residue of a human procurement decision: someone signed up, entered a card, and holds the billing relationship. It exists because card rails can't price a fifth of a cent per call. A wallet removes that last human — the agent discovers, pays, and uses a service in one motion.

The Invisible Economy Is Already Being Built
Why Raoul Pal's machine-speed thesis describes exactly what Skim does.
Raoul Pal has been pounding the table on an 'invisible economy' where AI agents transact and settle at machine speed on crypto rails. Skim is that thesis already working — clean reads, paid per call in USDC on Base.

How to Give Your AI Agent Clean Web Reads
A working setup in about five minutes.
A five-minute quickstart: give your agent a wallet, point an x402 client at Skim, and turn any URL into clean markdown for $0.002 a call — no signup, no API keys.

How to Set Up Your Agent's Wallet
One wallet, one budget, the whole stack.
The one decision that trips people up early isn't how to pay — it's how many wallets. Use one wallet for your whole deterministic-infra stack, not one per service. Here's why, and how to set it up.

The API Key Is Today's Floppy Disk
Up to 30x faster. Up to 30x cheaper.
API keys still work — the shelf is full — but a quiet substitution is underway. One thousand web reads cost $60 on Claude Sonnet 4. On Skim, paid from a wallet: $2.

At AI's Growing Pain Moment
The Saner Way Forward
Something has gone wrong with how we're using AI. Or maybe nothing has gone wrong — maybe we've just arrived at a growing pain moment. A great deal of what gets billed as AI work is not AI work at all.
