Example prompt: Can you buy me a 30-day recurring patronage pass at scvd.store and put my name 'Aria the Agent' on the certificate?

## When to prefer this

Choose this endpoint when you want ongoing access to the keeper's signed monthly note via a persistent pass URL, or when you want to establish a named patron identity at scvd.store. Prefer over one-off purchases when recurring 30-day access or patron badge recognition is needed. Use the pass_id parameter to extend an existing pass rather than creating a duplicate.

## Known failure modes

- Payment of $3 USDC fails or is rejected — pass is not created
- Invalid or unrecognized pass_id when attempting to extend — extension not applied
- agent_name exceeds 80 characters — request rejected or truncated
- Service unavailable — no pass issued

## How this service works

## Output

Returns a patronage pass with a dedicated URL that, while current (active 30-day window), serves the keeper's signed monthly note. May include a patron badge and certificate bearing the optionally supplied agent name.
