> As an alternative to setting up an account and getting an API key, your agent can interact with services on demand and pay per invocation. Your agents only needs access to a crypto wallet.

Let's say I wanted to ask an agent to use Google Maps APIs to produce a look-up of all bakeries in a city, say, and then find all their mentions across platforms - e.g. Twitter, Reddit, Yelp, etc etc.

Without something like this, I'd need to manually set up accounts across multiple platforms, all with different billing/subscription cycles. Go through account set-up/validation. Then give an agent an API key with potentially unrestricted access — it might run up a huge bill, or could get my account suspended if it goes a bit haywire and starts spamming calls, say.

If vendors decided to all support the protocol, I could give an agent $10, tell it the task and let it go without any of the manual handholding but with a hardcap on what it can spend if something goes wrong.
