RunAPI

@runapi-ai

What This Skill Does

Provides a unified API endpoint to call GPT-5 series chat, reasoning, and Codex models, plus OpenAI text embeddings, through any OpenAI-compatible SDK by simply changing the base URL and API key. Supports Chat Completions, Responses API, and Embeddings endpoints with no client code changes beyond configuration.

Replaces managing separate API keys and endpoints for each OpenAI model family by routing all GPT, reasoning, Codex, and embedding calls through a single RunAPI base URL.

When to Use It

  • Call GPT-5 chat models from Python or TypeScript using the official OpenAI SDK
  • Generate text embeddings for semantic search or vector databases
  • Use reasoning models with configurable effort levels (low/medium/high)
  • Run Codex coding models for code generation or completion tasks
  • Stream chat completions from GPT models in real-time applications
  • Switch an existing OpenAI SDK integration to RunAPI by changing only the base URL and API key

Install

$ openclaw skills install @runapi-ai/runapi-gpt

GPT on RunAPI

Use OpenAI-compatible clients at https://runapi.ai/v1 as the primary protocol.

Primary protocol recipe

Authenticate

Set OPENAI_API_KEY to a RunAPI API key and OPENAI_BASE_URL to https://runapi.ai/v1.

Send request

from openai import OpenAI
client = OpenAI(api_key="YOUR_RUNAPI_TOKEN", base_url="https://runapi.ai/v1")
response = client.responses.create(model="gpt-5.5", input="Summarize this review.")
print(response.output_text)
print(response.usage)

Use client.chat.completions.create for gpt-5.2, which does not accept Responses. Use Responses for gpt-5.*-pro. Use client.embeddings.create only with the three embedding model IDs below. For streaming Responses, set stream=True and consume through one usage-bearing response.completed followed by [DONE].

For gpt-5.6-luna, gpt-5.6-sol, and gpt-5.6-terra, start with text input, sync or SSE transport, parameterized custom functions, and automatic prompt caching. gpt-5.3-codex-spark has the same verified subset with parameterless custom functions. Add reasoning controls, multimodal input, hosted tools, or continuation state only when the current RunAPI contract verifies that shape.

Verify result

Responses require final output, response.completed, and usage. Chat requires final assistant content, finish_reason, and usage. Embeddings require one numeric vector per input and response usage.

Stop boundaries

Correct a rejected shape once using the current error and endpoint contract. Retry transport once only before any response or Usage and when replay is safe. Record a terminal error and stop without changing model, endpoint, or protocol. Keep embedding models on /v1/embeddings.

Compatibility protocols

Load compatibility protocols only when an existing client requires Anthropic Messages or Gemini contents.
