Pricing questions

Which calls count toward my quota?
Only successful 2xx responses. Errors and timeouts are never billed, and calls count across every feed on one key.
What happens when I go over my plan?
Card plans keep working and bill overage: $0.001 per call on Builder, $0.0005 per call on Scale. USDC plans stop at the quota until the term ends, unless the key has prepaid credit, which then pays per call at each endpoint's price.
Does a USDC plan renew automatically?
No. A USDC payment on Base, Ethereum or Solana covers 30 days. Paying again for the same plan adds 30 days to the current term.
How do I cancel a card plan?
Cancel any time in the Stripe billing portal. Access runs to the end of the paid period.
Can my agent pay without an account?
Yes. Agents pay each request in USDC with x402: no account, no key, no subscription. They can also buy a plan or a time pass in one x402 payment on Base.
What is the difference between a plan and a time pass?
A plan covers every feed with one key and a monthly call quota. A time pass covers one feed and is paid in USDC: from any wallet on Base, Ethereum or Solana, it lands on an agent key for that feed (created for you if you only have a free key), or your agent buys it with x402 and it is added to the agent's key.
