What it does

Openagents API is an agent skill from OpenAgentsInc/openagents. Call the OpenAgents API (Open Responses and Chat Completions, many models, one key) and read its docs. Use when a task needs a model through OpenAgents, or asks what OpenAgents models cost.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering LLM API integration. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit f3e551c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- openagents.com
- api.openagents.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- OPENAGENTS_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Openagents API loads about 430 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 161 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~51
When it runs · the whole SKILL.md, loaded when a task matches: ~430

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

The full file from OpenAgentsInc/openagents at commit f3e551c, republished under its Apache-2.0 licence (© OpenAgentsInc). 161 words, ~430 tokens.

name: openagents-api
description: Call the OpenAgents API (Open Responses and Chat Completions, many models, one key) and read its docs. Use when a task needs a model through OpenAgents, or asks what OpenAgents models cost.

OpenAgents API

One API for many models. It speaks Open Responses and the OpenAI Chat Completions API, so OpenAI SDKs work with two changes. Beta.


Base URL	`https://api.openagents.com/v1` (also `https://openagents.com/api/v1`)
Key	`Authorization: Bearer $OPENAGENTS_API_KEY` (an `oak_` key)
Docs	https://openagents.com/docs/api.md
Prices	https://openagents.com/docs/api/models.md
Getting a key	https://openagents.com/auth.md

Steps

Read the key from OPENAGENTS_API_KEY. If it is missing, tell the person to make one at https://openagents.com/settings/api-keys; never ask for it in chat or write it to a file.

Send a request:

curl https://api.openagents.com/v1/responses \
  -H "Authorization: Bearer $OPENAGENTS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "openagents/chat", "input": "Say hello."}'

openagents/chat lets OpenAgents pick the model. Name one (see the prices page) to choose it yourself.

With an OpenAI SDK, set base_url to https://api.openagents.com/v1 and pass the key as the API key.
On 429, wait for Retry-After. On 402, the balance is too low; tell the person. Every answer has an x-request-id to quote when asking for help.

Reading the docs as tools

The docs MCP server at https://openagents.com/mcp/docs (Streamable HTTP, no key) has list_docs, search_docs, read_doc, and list_models.
