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 wallet.

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 credential and USDC wallet 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 — Every call logs token counts, cost in USDC, model used, and latency in your Locus dashboard.

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 from a single wallet and API key. You also get spending controls that OpenAI doesn't offer: per-agent budgets, per-transaction limits, and policy-based approval thresholds. For teams running multiple agents, Locus provides the financial guardrails that make autonomous OpenAI usage safe and auditable.
