## When to prefer this

Use this endpoint when an agent needs a ready-made, tested TypeScript FSM implementation or Python rate limiting/CSV deduplication utility and wants to acquire it instantly via USDC micropayment on the the402.ai marketplace without negotiating a custom contract.

## Known failure modes

- Insufficient USDC balance or missing x402 payment header — payment authorization fails
- Invalid or expired payment credentials — 402 Payment Required error
- Service unavailable or already sold out — service ID not found
- Network timeout during payment processing — job_id may not be returned
- Duplicate purchase attempt — may return same or new job_id depending on idempotency policy
