Configuration is available with version, account, region or feature restrictions. Read the conditions below first.

Before you begin

Install the VS Code or JetBrains plugin linked by CodeBuddy. Hosts and enterprise versions may differ; first confirm a URL field exists.

Have an A2Agent API key ready and copy an accessible model ID from the catalog. Replace every placeholder, back up existing settings and keep keys out of repositories.

Manage API keys Browse models

Setup

File contents are usually shared; switching OS changes commands and paths. For WSL on Windows, select macOS / Linux.

01Check the custom-model entry
Find Configure Custom Model in the chat model menu and choose Custom. If unavailable, check enterprise policy or use CodeBuddy Code CLI.
Open official documentation
02Save and select the model
Enter the URL, key and model ID. The example uses a full request URL. Reopen the panel after saving and select the model.
text
```
Provider: Custom
URL: https://a2agent.me/v1/chat/completions
API Key: YOUR_A2AGENT_API_KEY
Model ID: YOUR_MODEL_ID
```

Capabilities and limits

This guide applies only to plugin versions with an explicit Custom URL field.
Verify inline completion and enterprise knowledge features separately; working chat does not configure them.

Verify the connection

Replace every placeholder and run locally. Expect JSON containing OK. Then start a new client conversation, test one read-only tool call separately, and confirm the requests in A2Agent usage records. This test incurs a small amount of model usage.

Shell

curl --fail-with-body --silent --show-error --max-time 60 'https://a2agent.me/v1/chat/completions' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_A2AGENT_API_KEY' \
  -d '{"model":"YOUR_MODEL_ID","max_tokens":128,"messages":[{"role":"user","content":"Reply with OK."}]}'

Troubleshooting

If the entry is missing, do not put the key in official sign-in fields. Check the version or use the CLI below.

401 / 403: authentication or access denied

Use a key issued by A2Agent, without extra spaces, and check that it is active and unexpired. Confirm the group permits the model and protocol. A vendor subscription credential cannot replace an A2Agent key.

404 / model not found: endpoint or model mismatch

Check the root URL, /v1 prefix and full request path against this guide; avoid duplicated paths. Model IDs are case-sensitive and must be accessible to the current key.

429: quota or rate limit

Check your balance, key limits, concurrent usage and service status. Wait before retrying and reduce simultaneous agents; repeated retries do not remove a quota limit.

Chat works, but tools fail or streaming stops

Test a short text request, then a single read-file tool call. Check tool support, output budget, proxy timeouts and client version. Inspect the diff before resuming a long task to avoid repeating actions.

Restore previous settings

Return to an official model and delete the added Custom configuration and credential.
