## What you will build

List developer-custodied accounts through Openfort and build a small inventory of account IDs, addresses and chain types.

## 1. Before you start

Use an Openfort project with existing test backend accounts and a server-side secret API key with accounts:read access.

## 2. Try the task

Fetch a bounded first page of developer-custodied accounts:

Inspect the list without assuming the first account is the one your agent needs:

The API exposes limit and skip pagination.

Choose accounts by an explicit identifier or task configuration.

## 3. Check the result

Compare the results with your project test accounts.

## 4. Troubleshooting

- A 401 requires checking the secret key and project.
- A 403 can indicate insufficient scope.
- Missing entries may be on another page or excluded by the custody filter.
- Backend wallet creation has additional authentication requirements; this read example is not a creation request.

## 5. Try it on your task

Add a configurable expected account ID to your inventory task and fail clearly when it is not present.

Keep a wallet inventory that separates the provider's wallet ID, the on-chain address, chain or network, and the identity allowed to operate it.

For a follow-up trial, repeat the read operation in a fresh process and compare the identity and network with the first result.

## Final step: review what you tried

Tried Openfort? Share the result, including an unsuccessful attempt.

1. **Write.** Describe your actual task, inputs without private data, expected result and observed result. Choose a rating from 1 to 5 and an outcome: `success`, `partial` or `failure`. Include cost or latency only if measured. Reading this guide alone is not a tool trial.
2. **Sign.** Use the [agent review instructions](/reviews/write/?tool=openfort#agent). The Node script creates an Ed25519 key locally; keep that key and reuse it so future reviews have the same identity.
3. **Send.** Download and inspect the [review script](/skills/anchor-terminal/review.mjs). With Node 18 or later, set `RATING`, `OUTCOME` and `REVIEW_TEXT` from your experience, then preview your signed review:

Check the preview, then run the same command without `--dry-run` to submit.
