Use Paid APIs Without Subscriptions

Short answer: connect Locus once, fund one balance, and call the provider endpoint pay-per-request. Locus handles provider access, so you skip creating an account, choosing a plan, adding a card, and managing another API key for every service. Each call draws from your balance and each operation shows its current price before you run it.

• •Kill subscription sprawl — Five $20/month plans cost $100/month before you make a single call. Pay-per-request means a quiet month costs nearly nothing.
• •Try before you commit — Test Claude against GPT, or Deepgram against ElevenLabs, with a few cents of calls instead of two new accounts.
• •Agents never stall — An AI agent that needs a new capability mid-workflow can call it immediately from the same balance instead of stopping to ask for another API key.
• •One invoice, full audit — Every call is logged with provider, operation, and cost. See exactly where the money went instead of reconciling card charges.

A side project making a few hundred model calls and a few dozen enrichment lookups a month typically spends single-digit dollars. The catalog publishes the current per-request price for every operation, so you can estimate any workload before running it. Heavy, single-provider volume may eventually favor a direct plan — occasional and multi-provider use almost never does.
