# IsDelegate REST API

A simple public API for checking if a wallet has valid IsDelegate attestations.

## When to Use

Use this API for:

* Quick authorization checks with minimal code
* Simple bot detection
* Verifying agent status without cryptographic validation

**Important:** This API requires trusting Zipwire's validation. For maximum security and cryptographic verification, use the [ProofPack library](/tools-and-integrations/proofpack-agent-delegation.md) instead.

## Endpoint

```
GET https://zipwire.io/api/v1/is-delegate/{walletAddress}
```

## Request

| Parameter       | Type   | Description                           |
| --------------- | ------ | ------------------------------------- |
| `walletAddress` | string | Ethereum wallet address (0x-prefixed) |

## Response (Success)

```json
{
  "success": true,
  "message": "IsDelegate attestation verified successfully",
  "walletAddress": "0x775d3B494d98f123BecA7b186D7F472026EdCeA2",
  "attestations": [
    {
      "attestationUid": "0x7e08febe71e51acbdcb1d2c6175fb36958594074bed0f1e85b12adc6274eb8b2",
      "attestationExplorerUrl": "https://base.easscan.org/attestation/0x7e08febe71e51acbdcb1d2c6175fb36958594074bed0f1e85b12adc6274eb8b2",
      "valid": true,
      "pointsToHuman": true
    }
  ]
}
```

## Response (No Attestations)

```json
{
  "success": false,
  "message": "No delegation attestations found for wallet",
  "code": "NoAttestationsFound",
  "walletAddress": null,
  "attestations": null
}
```

## Example Usage

**JavaScript:**

```javascript
const response = await fetch('https://zipwire.io/api/v1/is-delegate/0x775d3B494d98f123BecA7b186D7F472026EdCeA2');
const result = await response.json();

if (result.success) {
  console.log('Agent is authorized by a human');
} else {
  console.log('Agent is not authorized');
}
```

**cURL:**

```bash
curl https://zipwire.io/api/v1/is-delegate/0x775d3B494d98f123BecA7b186D7F472026EdCeA2
```

## Notes

* No authentication required (public endpoint)
* Always returns HTTP 200 OK
* Validation includes revocation and expiration checks
* Walks the full delegation chain back to Zipwire's trusted root

## For Maximum Security

For cryptographic verification that doesn't require trusting Zipwire's API, use the [ProofPack library](/tools-and-integrations/proofpack-agent-delegation.md) instead. ProofPack allows you to verify attestations independently on-chain.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zipwire.io/fundamentals/security/attestations/is-delegate-rest-api.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
