The end of subscriptions
We killed
the subscriptions.
An agent that needs six tools today means six accounts, six API keys and six monthly bills, most of it paying for capacity you never use. With AMXP your agent has one balance and pays for the calls it makes. Nothing else.

Common questions
Common questions.
Do I need an API key for each provider?
No. Your agent connects to AMXP once. AMXP holds the provider relationships and credentials, and every call is paid from your one balance.
How is pricing structured?
Pay per call. Your agent sees the price of a call before it runs it, the cost is reserved from your balance, and only the exact amount is settled afterwards. There are no subscriptions and no minimums.
What if a provider fails?
If a call fails on the provider's side, the reserved amount is released back to your balance.
Which agents does it work with?
Anything that can read a skill file, speak MCP, run a CLI or make an HTTP request: Claude, ChatGPT, Cursor, custom agents built on any framework.
Can I limit what my agent spends?
Yes. Set a monthly cap, a per-call ceiling and an auto top-up threshold. Your agent cannot spend past the limits you set.
Is AMXP live?
AMXP is in private preview. The catalog shows which providers are live and which are coming soon.
