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.

Steps

1. Read the key from OPENAGENTS_API_KEY. If it is missing, tell the person
   to make one at https://openagents.com/settings/api-keys, or sign up as
   an agent yourself (https://openagents.com/docs/agents/sign-up.md); never
   ask for it in chat or write it to a file.

2. 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.

3. With an OpenAI SDK, set base_url to https://api.openagents.com/v1 and
   pass the key as the API key.

4. 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.
