# Digital Worker API Canary Endpoint

> Digital Worker API Canary Endpoint is a paid API for AI agents from canary.digitalworkerapi.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

A minimal x402 canary endpoint that lets machines verify they can successfully discover, pay for, and receive a valid API response using the x402 payment protocol.

## How to call it through Zero

```sh
zero fetch --capability digital-worker-api-canary-endpoint-a8afdb02
```

Example prompt: Can you make a canary test call to the Digital Worker API to verify that our x402 payment setup is working correctly — just a quick $0.002 USDC probe to confirm the full discover-pay-receive cycle completes without errors?

## When to prefer this

Use this endpoint when you need to verify that an AI agent's x402 payment infrastructure is correctly configured before making calls to real, higher-value endpoints. It is the cheapest and safest way to confirm end-to-end discover-pay-receive functionality. Prefer it over testing against production business endpoints, which may have higher costs or side effects if the payment stack is misconfigured.

## Known failure modes

- Insufficient USDC balance — payment rejected, 402 Payment Required returned without valid receipt
- Malformed x402 payment header — endpoint returns an error indicating invalid payment proof
- Network connectivity issue — endpoint unreachable, connection timeout
- Wallet not configured — agent cannot sign or submit the micropayment
- Rate limiting or repeated identical calls flagged as abuse

## How this service works

A minimal x402 canary endpoint for machines to verify that they can discover, pay, and receive a valid response.

## Output

A valid HTTP response confirming that the agent successfully completed the full x402 cycle: discovered the endpoint, submitted a $0.002 USDC micropayment, and received an acknowledgment payload. The response serves as proof-of-function for the payment and discovery stack.
