omnicall-agent

An autonomous AI agent in ~150 lines — with no API keys. The brain (248 LLMs) and the tools (live web search) are one keyless, pay-per-call endpoint: Omnicall. Pay per call in USDC via x402 on Base/Solana, or with a gck_ credit key. It runs free out of the box.

npx omnicall-agent "What is the x402 protocol and who is building on it?"

That's it — no OpenAI key, no Anthropic key, no signup. The agent picks a model, searches the web when it needs facts, and answers.

Why this exists

Most "agent starter kits" make you sign up for an LLM provider, paste a key, add a billing card, then wire up a separate search API with its key. omnicall-agent needs none of that. One endpoint gives an agent every model plus tools, and it pays per call — so you can ship an autonomous agent with zero accounts and pay only for what it actually does.

Two modes

| Mode | Setup | What you get | |------|-------|--------------| | Free | nothing | Single-shot answer on the free tier. Instant. | | Agentic | OMNICALL_KEY | Full reason→search→verify loop over 248 premium models + live web search. |

# Free — runs immediately
npx omnicall-agent "Summarize the latest on agent payments"

# Agentic — unlock tools + premium models with a credit key (or x402 wallet)
export OMNICALL_KEY=gck_your_key      # get one at https://omnicall.gocreativeai.com

Environment

| Var | Default | Purpose | |-----|---------|---------| | OMNICALL_KEY | (none) | gck_ credit key or x402-funded key. Unlocks the agentic loop. | | OMNICALL_MODEL | auto | Model id. auto routes to the cheapest capable model. | | OMNICALL_URL | https://omnicall.gocreativeai.com | Gateway base URL. |

How it works

The agent is a simple loop against Omnicall's OpenAI-compatible gateway:

1. Send the goal to a model (POST /v1/chat/completions, model: "auto").
2. If the model asks to look something up (SEARCH: <query>), the agent calls GET /v1/web/<query> and feeds the result back.
3. Repeat until the model returns a FINAL: answer.

Every call is metered and paid per-use — no subscription, no idle cost.
