Use case
Pay-per-use AI services
The problem
AI services require API keys, credit cards, accounts, and monthly subscriptions. This creates friction for autonomous agents that just want to pay per call.
The solution
X402 and pay.sh / MPP enable HTTP 402 payments. Agents pay per request with USDC, no accounts needed. Send a payment header with the request; the service returns the response.
How it works
01
No account needed
No signup, no API keys, no credit cards.
02
X402 / MPP payment
Pay per request in USDC on the chain your agent already uses.
03
Instant response
Service returns the answer in seconds.
