# AiCredential `ai.credential@1`

Generated at 2026-11-13 06:25:48 UTC from [`openvibe-contracts v0.419.0`](https://github.com/OpenVibers/OpenVibe.Contracts/tree/v0.419.0) and [`openvibe-sdk v0.161.0`](https://github.com/OpenVibers/OpenVibe.SDK/tree/v0.161.0).

An older major, still in the catalog. The current one is [`ai.credential@2`](/docs/contracts/ai.credential).

- Version: 1.0.0
- Owner: ai
- Visibility: first-party
- Status: active
- Compatibility: backward
- Schema: [`https://openvibe.network/contracts/ai/credential.v1.json`](/docs/contracts/ai.credential@1.json)

ai.credential@1 (OpenVibe.AI; roadmap WS-O task 2): a stored credential as its owner service reads it (GET or PUT /api/v1/credentials/{subject}): never the key, only its last four characters.

## Examples

From the contract's own test fixtures: valid ones validate, rejected ones must fail.

The fixtures that ship with the package are the current major's.

## Validate

~~~~
const contracts = require('openvibe-contracts');
contracts.validate('ai.credential@1', value);   // { valid, errors: [{ path, message }] }
