## 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-financial-evidence-e7e01a63 -d '<json body>'
```

Example prompt: Can you produce a cryptographically attested financial evidence artifact for Acme Corp's Q3 2024 income statement — the figures are revenue $4.2M, operating expenses $3.1M, net income $1.1M — and give me the signed artifact I can use for audit purposes?

## When to prefer this

Choose this endpoint when you need a cryptographically signed, tamper-evident attestation of financial statement figures for audit, compliance, or governance purposes and can supply the figures directly. It is ideal when you require an Ed25519 + SHA-256 signed artifact rather than a plain analysis, and when paying per-call via USDC on Base mainnet (x402) is acceptable. Prefer alternatives if you need live market data ingestion, bulk batch processing, or non-financial document attestation.

## Known failure modes

- Payment not settled — returns HTTP 402 with x402 v2 payment-required envelope if USDC payment on Base mainnet (chain ID 8453) is not confirmed
- Missing required fields — if 'company', 'period', or 'statement' are absent the request is rejected
- Malformed statement object — if financial figures are not structured as valid key-value rows, processing fails
- External market data not available — the service explicitly derives findings only from supplied figures, so market-sourced data is not incorporated

## 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

Returns a JSON object with an 'ok' status and an attested evidence artifact containing the financial analysis findings derived solely from the supplied figures, cryptographically signed with Ed25519 and hashed with SHA-256, suitable for audit, compliance, and governance use.
