The vendor documents custom endpoints. Check model capabilities and verify the connection.

Before you begin

Install current CodeBuddy IDE. If Configure Custom Model is absent, update and check enterprise policy.

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.

Setup

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

01Open configuration
In the conversation model list, select Configure Custom Model and choose Custom as the provider.
Open official documentation
02Add and select the model
Enter the full endpoint, key and model ID below. Save, reopen the panel and select the new model.
text
```
Provider: Custom
Base URL: https://a2agent.me/v1/chat/completions
API Key: YOUR_A2AGENT_API_KEY
Model ID: YOUR_MODEL_ID
```

Capabilities and limits

IDE and CLI releases can differ in configuration fields. Prefer the current UI’s custom-model entry.
Separate features such as code completion are not verified by this guide.

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

Reopen the panel if the model is missing after saving. For a 404, check whether this version’s Base URL field expects a full path.

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

Select the previous model and delete the added Custom model and its credential.
