Locus Pro · Prepaid tool credits

OpenAI Pay Per Use

Access reviewed GPT and o-series models plus OpenAI embeddings, image, speech, and moderation tools with usage-based pricing through one Locus Pro credit balance.

Updated

Use OpenAI without a subscription

Direct OpenAI access requires its own account, payment method, API keys, and billing controls. Through Locus, reviewed OpenAI operations share one Locus Pro credential and credit balance with your other agent tools. Chat calls use an OpenAI-compatible messages format, while the catalog documents the supported request fields and current pricing basis for every operation.

Available OpenAI capabilities

Current GPT models

The reviewed chat catalog includes the GPT-5.6 family plus GPT-5.5, GPT-5.4, GPT-5.2, and GPT-4.1. Calls are token-metered, and the live catalog is the source of truth for availability.

Reasoning models

Reviewed GPT and o-series models support reasoning workloads. The endpoint metadata identifies the correct output-token field and incompatible parameters for each model.

Embeddings

Generate vector embeddings for semantic search, clustering, and classification with token-metered pricing.

Images, speech, and moderation

Separate catalog operations cover image generation, text-to-speech, and content moderation with their own reviewed request shapes and pricing models.

How to call OpenAI through Locus

Use Locus's OpenAI-compatible chat-completions route with your Locus API key. It supports reviewed model IDs, text and vision messages, tools, structured output, and streaming. Check the catalog metadata for model-specific fields such as max_tokens versus max_completion_tokens instead of assuming every upstream parameter applies to every model.

  • •OpenAI-compatible format — Use the familiar chat-completions request and response shape for the documented, reviewed parameter set.
  • •Streaming supported — Server-sent events streaming works just like OpenAI's native streaming.
  • •Usage tracking — Review the recorded operation, usage, and charge in your Locus Pro account. Available usage fields depend on the operation.

Why use Locus for OpenAI access

If you only use OpenAI, a direct account works fine. But most AI agents use multiple providers — OpenAI for general reasoning, Anthropic for long-context tasks, DeepSeek for cost-efficient coding, Tavily for search. Locus lets you access all of them through one Locus Pro account. Locus Pro adds shared balances, supported account and connection controls, and usage records across supported providers. Compare coverage and current prices with direct access for your own workload.

Connect and control usage

Locus Pro uses prepaid credits. Start with the agent connection guide, review current plans, and configure spending controls before scaling a workflow. Pay With Locus is the separate on-chain wallet product.

Frequently asked questions

Do I need an OpenAI account to use GPT models through Locus?

No. Reviewed OpenAI operations use your Locus Pro credential and credit balance, shared with your other agent tools.

Does Locus support OpenAI streaming?

Yes. The OpenAI-compatible chat-completions route supports server-sent events streaming, plus tools, structured output, and vision messages.

Can I send every OpenAI parameter?

Not always. The route supports a documented, reviewed parameter set. Check the catalog metadata for model-specific fields such as max_tokens versus max_completion_tokens.

Should I use Locus if I only use OpenAI?

A direct OpenAI account works fine if OpenAI is your only provider. Locus helps when an agent uses several providers through one account. Compare coverage and current prices for your workload.
