Developer console

The developers page on your dashboard (menu → developers) holds the settings for building with pong: the key your programs use, which model pong runs on, and secrets for the tools pong runs for you.

Secret key#

• One key per account. It starts with pong_ and is shown once, so copy it when you create it.
• Programs send it as Authorization: Bearer <key> to your published link. A person opening the link in a browser still signs in with their phone.
• Replace makes a new key and turns the old one off. Revoke turns it off with no replacement.

Run pong on your ChatGPT plan#

1. 1

   Start

   Tap Sign in with ChatGPT. A code appears.

2. 2

   Approve at OpenAI

   Open the OpenAI page, sign in and enter the code. OpenAI will say you're signing in to the Codex CLI. That's expected: pong signs in the same way. Only continue if you just started this and the code matches.

3. 3

   If OpenAI asks you to enable device code sign-in

   Turn it on in ChatGPT settings → Security, then tap New code.

4. 4

   Pick a model

   Once connected, choose GPT-6 Astra (the default), GPT-6.1 Sol, GPT-6 Sol or GPT-6 Luna. Plus and Pro use the allowance you already pay for.

Custom gateway: your own model#

Point pong at any OpenAI-compatible endpoint: OpenRouter, a LiteLLM proxy, vLLM, LM Studio, Ollama, or your own server. Fill in three things: the Address, the Key, and the Model your endpoint serves.

• The address must be https:// and is usually the base that ends in /v1.
• Model is the exact name your endpoint expects in the model field, like llama3.1:8b on Ollama, meta-llama/Llama-3.1-70B-Instruct on vLLM, or anthropic/claude-sonnet-4.5 on OpenRouter. pong sends that name on every call.
• The model needs tool calling (function calling) and a generous context window. pong is an agent, not a chatbot, and leans on both.
• A model on your laptop isn't reachable as localhost. Expose it on a public HTTPS address first, for example with a tunnel.
• If both a ChatGPT sign-in and a gateway are set, the ChatGPT sign-in wins.

curl https://your-endpoint.example.com/v1/chat/completions \
  -H "Authorization: Bearer $KEY" -H "Content-Type: application/json" \
  -d '{"model":"llama3.1:8b","messages":[{"role":"user","content":"hi"}]}'

Custom env#

Keys for the tools pong runs on your computer: an API token for a service your script calls, say. Add a name and a value; commands pong runs get them as environment variables. Values stay on your computer and are never shown again.

Names

Capital letters, digits and underscores, starting with a letter. Like STRIPE_TEST_KEY

Reserved

Names pong uses itself, like anything starting with PONG_ or OPENAI_. The page tells you if a name is taken

How many

Up to 20 keys, each value up to 400 characters
