OnAPI vs Cursor AI

OnAPI is a unified API gateway that lets developers call GPT, Claude, Gemini, Sora, Veo, and Google's Nano Banana image model through a single key. Swap your SDK base URL to OnAPI's endpoint, plug in an OnAPI key, and keep the rest of your integration unchanged.

The gateway speaks OpenAI-compatible and Anthropic-compatible protocols, so chat completions, Anthropic messages, streaming, function calling, and long-context requests work without a rewrite. OnAPI says new upstream models typically appear within 24 hours of release.

Two routing channels share the same account. The economy channel bills at a 1:1 rate multiplier for everyday volume. The official channel routes through paid keys tied directly to provider accounts at a 1:7.5 multiplier when you need a straighter path to upstream APIs.

OnAPI is aimed at builders shipping AI products, especially where direct provider billing is inconvenient. Top-ups run through Alipay, WeChat, USDT, and USDC. Account balance does not expire, and the site states there is no minimum spend.

The service runs on the open-source New API project (based on One API), which handles model aggregation and cross-format conversion between provider APIs.

Cursor AI gives developers an agentic coding environment where you delegate implementation work while keeping architectural control. The editor indexes your full codebase, runs multi-step agents in the IDE, terminal, Slack, and GitHub, and ships changes through Tab autocomplete, Composer edits, and cloud agents that can build and demo features end to end. A free Hobby tier requires no credit card to start.

Compared with chat-only copilots that suggest single lines, Cursor AI runs parallel agents on their own machines and ties into Bugbot for pull request reviews. Individual plans start at $20 per month with frontier models, MCP servers, and cloud agents, while Teams adds $40 per user billing with SAML SSO and shared team context. That agent-first stack suits fast-moving product teams, though usage-based model billing can add cost after included limits.

Software engineers, startup teams, and enterprise developers use Cursor AI to migrate from VS Code with one-click extension imports, trigger tasks from issue trackers, and enforce privacy mode so code is not used for training. The pricing page lists Pro, Pro+, and Ultra individual tiers plus Enterprise with pooled usage and audit logs. Contact for sales and support is available at [email protected].
