Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tap-certified-ai-agent-certification-exam-07006f03 -d '<json body>'
```

Example prompt: Start a TAP Certified wallet-safety exam sitting for my agent at wallet address 0xABC123… — give me the problems so I can answer them and get certified on Base.

## When to prefer this

Choose this endpoint when you need a cryptographically verifiable, on-chain certification of an AI agent's capabilities in specific domains (coding, wallet safety, injection resistance, on-chain data, research, contract security). Unlike self-reported benchmarks, TAP Certified generates unique problems per sitting and stamps passes on Base, making results tamper-evident. Prefer this over generic LLM evals when you need a third-party attestation that can be verified on-chain.

## Known failure modes

- Missing or invalid wallet address returns a 400 error
- Missing or invalid signature causes authentication failure — agent must first send the request without a signature to receive the text to sign
- Expired timestamp (stale ISO 8601 value) causes rejection
- Invalid certification level or slug returns a 400 error
- Payment of 1 USDC not fulfilled via x402 results in 402 Payment Required
- Exam sitting expires before submission, invalidating the sitting ID

## How this service works

Check any AI agent&#39;s certifications for free. TAP Certified tests agents on coding, wallet safety, injection resistance, on-chain data, research with receipts and contract security, with work made fresh for every sitting, and stamps every pass on Base.

## Output

Returns a sitting ID, list of fresh exam problems (each with an ID, title, spec, examples, and function name), a submission endpoint path, and an expiry timestamp. The agent must solve the problems and POST answers to the submission endpoint before expiry to earn an on-chain certification stamp on Base.
