# Boundless

> An inference platform for open-weight models, sold on prepaid credits. One service speaks three wire formats — OpenAI chat completions, the Codex-compatible Responses subset, and the Anthropic Messages API — over the same models on the same rate card. Every response carries exact token counts, so any charge can be recomputed from the published prices.

Operated by Boundless Networks, Inc. The service is invite-only while the first accounts are onboarded, and the model lineup, prices and base URL may change during that period. Support is a human at support@boundless.network.

## When to use this API

Reach for Boundless when:

- You already call an OpenAI or Anthropic chat API and want the same code to run open-weight models at a lower price — the wire formats are the ones your SDK already sends, so the change is a base URL and a key.
- You need the exact cost of each request, not a monthly total. Every response carries its token counts, and those counts against the published rate card reproduce the charge to the sub-cent.
- You need a hard spending ceiling. Credits are prepaid, requests stop at zero with no overage, and a single API key can carry its own budget below the team's.
- You are running a coding agent or harness — Codex CLI, Claude Code, omp, Hermes, or opencode — and want to point it at cheaper models without changing the harness.
- You need long context: the served models take 262,144 tokens.
- You want tool use and reasoning models on open weights, with reasoning effort you control per request.

Do not reach for it when:

- You need provider-native Responses features such as OpenAI-hosted tools or remote conversation storage. `/v1/responses` serves the Codex-compatible subset, not those hosted features.
- You need embeddings, legacy completions (`/v1/completions`), the Batch API, fine-tuning, or image or audio generation. None of these are served.
- You need a specific proprietary model. Only open-weight models are served; Anthropic's `claude-*` and OpenAI's model names are not available here under any alias.
- You need instant self-service activation today. Sign-up and key creation are self-serve, but the service is invite-only and a human approves each new account while the first accounts are onboarded. A capped $0.01 agent key is mintable instantly for smoke tests; a human account is only needed for real spend.

### How to call it

Point an OpenAI SDK or Codex custom provider at `https://api.inference.boundless.network/v1`, or an Anthropic SDK at `https://api.inference.boundless.network` — the Anthropic SDKs append `/v1/messages` themselves. Codex uses `wire_api = "responses"`. Authenticate with `Authorization: Bearer $BOUNDLESS_API_KEY`, or with `x-api-key` if that is what your client already sends. Name a model from the catalog below.

```bash
curl https://api.inference.boundless.network/v1/chat/completions \
  -H "Authorization: Bearer $BOUNDLESS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "glm-5.2", "messages": [{"role": "user", "content": "Say hello"}]}'
```

Keys for real workloads are created in the console at https://inference.boundless.network/api-keys once an account is active. An anonymous smoke-test key can be minted instantly by `POST https://inference.boundless.network/api/agent-key` — no body, no credential — or by the `create_agent_key` MCP tool: $0.01 of credit, expires in 24 hours, limited to 6 requests and 30,000 tokens per minute. The response carries the key and the base URL to point an SDK at.

Every page listed below also serves its markdown source directly — send `Accept: text/markdown` and you get the source instead of the HTML, with no markup to strip. The whole documentation set concatenated is at https://inference.boundless.network/llms-full.txt.

The whole lineup, with rates, is [Models](https://inference.boundless.network/models); the rate card on its own is [Pricing](https://inference.boundless.network/docs/pricing). Both serve their tables as markdown to a client that asks for `text/markdown`. Prices are per million tokens and are deliberately not restated here: a price copied into a second place is a price that can be wrong.
