## 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-document-conversion-0e364a72 -d '<json body>'
```

Example prompt: Can you convert this text to PDF format: 'This is my report content for Q3 2024. Revenue was up 12%.'

## When to prefer this

Choose this endpoint when you need a paid, cryptographically attested document format conversion with Ed25519 governance signatures via x402 micropayments on Base mainnet. Prefer this over free converters when the conversion result needs a verifiable, tamper-evident attestation artifact, or when integrating into a broader Synthex Forge verification and governance workflow.

## Known failure modes

- HTTP 402 returned if payment not included or invalid — must include valid x402 v2 payment-required envelope with USDC on Base mainnet
- Missing or empty 'text' field results in failed conversion
- Invalid 'to' format specifier may cause processing failure
- Payment amount mismatch (not 0.10 USDC) will reject the request
- Network or chain ID mismatch for Base mainnet will invalidate payment

## 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' boolean indicating success. The conversion result is attested with Ed25519 + SHA-256 signed artifacts per Synthex Forge's governance protocol. Requires prior x402 USDC payment on Base mainnet (chain ID 8453) at $0.10 per call.
