Choosing a Price

Consider:

how often the agent is used,
whether it depends on costly tools,
the value of the output,
support expectations,
whether the agent is experimental or production-ready.

Notes

Pricing metadata should match the actual value and reliability of the agent. Misleading pricing or unclear usage expectations can lead to poor user trust.
