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 synthex-forge-attested-research-brief-1072af2a -d '<json body>'
```

Example prompt: Generate an attested research brief on quantum-resistant cryptography at a deep depth level — I need the signed artifact for compliance review, include context about post-quantum NIST standards.

## When to prefer this

Choose this endpoint when you need a cryptographically attested, governance-grade research brief rather than a plain-text summary — ideal for compliance, audit trails, or governance workflows where verifiability of the research artifact is required. Prefer this over generic LLM summaries when you need an Ed25519-signed artifact that can be independently verified.

## Known failure modes

- 402 Payment Required if x402 USDC payment on Base mainnet (chain ID 8453) is not completed before request
- 400 Bad Request if topic or required fields are missing or malformed
- 500 Internal Server Error if attestation signing pipeline fails
- Timeout if research generation for deep-depth topics exceeds server limits
- Invalid payment envelope if USDC transaction is not confirmed on-chain

## How this service works

Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.

## Output

A JSON response containing an attested research brief on the requested topic, cryptographically signed with Ed25519 and SHA-256, delivered as a structured artifact suitable for governance, compliance, or audit purposes. The ok field confirms successful generation.
