Nevermined Catalogthe Router2 payment rails2 blockchainscapped budget
1 What it shows
An agent can act on its own in a paid world — safely, because you set the limit.
- The agent holds a small capped budget, like a prepaid card with a spending limit
- It pays each service directly, on demand, only for what it uses
- Nothing is arranged with any provider in advance — it discovers services as it goes
- Every purchase is a real payment recorded on a public blockchain
2 How it works
One prompt, four paid steps, in order — each through a service the agent found in the Catalog and paid via the Router. Across the four it used two payment methods over two blockchains, and never once asked a human to pay.
| Step | What the agent does | Service |
|---|---|---|
| 1 | Finds today's #1 technology headline | Brave |
| 2 | Writes 90s-pop-anthem lyrics about it | 2s.io |
| 3 | Turns the lyrics into a full, sung song | Suno |
| 4 | Paints a matching album cover | fal.ai |
3 Under the hood
# the only ability it's given is the Router it can pay through
"Find today's #1 tech headline, write 90s-pop-anthem lyrics
about it, generate a full song and matching album cover.
Discover every service in the Nevermined Catalog and pay
for each through the Router — never ask me to pay."4 See it run

The September 15 Live follow-up made seven Settled payments totaling $0.1605, delivered its first headline in 8 seconds, and consumed 20¢ of a 50¢ delegation cap. Its new audio and cover stay private; the playable media here is the earlier public reference run. Running the script yourself spends real money.
