Comparison of usage
How to use OnAPI?
Three steps to get up and running. OpenAI-compatible—no code rewrite needed: 1. Sign up and create an API key — Email signup, no international card required. Generate a key in the console with one click. New users get $0.20 in free credit. 2. Top up your balance — Pay with Alipay, WeChat Pay, or crypto. Pay-as-you-go, no minimum, use anytime, credits never expire. 3. Swap one line of code — Point base_url to https://api.onapi.ai/v1, drop in your OnAPI key, and you're live—fully compatible with the official OpenAI SDK. 4. Call any model — Supports Chat Completions, Anthropic Messages, streaming, function calling, long context, and every other native capability. Switch models by changing the model parameter—same request format, one key for GPT, Claude, Gemini, Sora, Veo, Banana, and the rest. 5. Track usage — Monitor request volume, token consumption, spend, and error rates per key and per model in the OnAPI console, in real time.
How to use LinkupAPI?
Create an account, retrieve an API key, review the documentation, and connect the required LinkedIn or other B2B accounts. Use the available REST API endpoints by sending requests with your API key and the necessary account credentials or login token. You can then build prospecting, enrichment, messaging, web extraction, recruitment, or AI-agent workflows, or connect LinkupAPI with no-code tools such as Make and n8n. API usage consumes credits according to the endpoint and action performed.
