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.
Example use cases
Pre-deployment x402 integration check
“Before I launch my AI agent in production, can you hit the canary endpoint to confirm the x402 payment flow is wired up correctly and we get a valid response back?”
Debugging a broken payment pipeline
“My agent stopped making successful API calls — can you try the canary endpoint to see if the underlying x402 payment mechanism is still working, or if something in the payment stack is broken?”
Onboarding a new agent wallet
“I just set up a new USDC wallet for my agent — can you run a canary call against the Digital Worker API to confirm this wallet can actually discover and pay for x402-gated endpoints?”
Technical details
Endpoint
GEThttps://canary.digitalworkerapi.com/v1/canary?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
