# Dokimo Verify API – Demo Merkle Proof Recomputation

> Dokimo Verify API – Demo Merkle Proof Recomputation is a paid API for AI agents from dokimo.augaster.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Recomputes a sample dokimo-merkle-v1 proof to its root as a demo of Merkle-based document verification (without on-chain anchor check)

## Facts

- Endpoint: GET https://dokimo.augaster.com/paid/verify?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-18

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 dokimo-verify-api-demo-merkle-proof-recomputation-9f5f214e
```

Example prompt: Can you run the Dokimo Verify demo to recompute the sample dokimo-merkle-v1 Merkle proof back to its root and show me the result?

## When to prefer this

Choose this endpoint when you want a lightweight, read-only demo of Dokimo's dokimo-merkle-v1 Merkle proof recomputation without triggering an on-chain anchor check. It is ideal for testing the proof scheme, exploring the API response structure, or validating that a proof recomputes to its root in a cost-effective way ($0.01 USDC). For full production-grade verification including on-chain anchor confirmation, use POST /paid/verify instead.

## Known failure modes

- Invalid or missing method parameter returns validation error
- Unsupported HTTP method enum value (only GET, HEAD, DELETE accepted) causes rejection
- Payment failure or insufficient USDC balance returns 402
- Service unavailable if Dokimo/Augaster backend is down

## How this service works

Dokimo Verify API (GET) - scheme demo: recomputes a sample dokimo-merkle-v1 proof to its root. For real caller verification, POST /paid/verify (recompute + on-chain anchor check). Scheme: /merkle-spec.html.

## Output

Returns the result of recomputing a sample dokimo-merkle-v1 Merkle proof to its root, demonstrating whether the proof is structurally valid. Does not perform on-chain anchor checking (use POST /paid/verify for full verification including blockchain anchor).
