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 response containing the filename ('x402-The-Agent-Economy.pdf'), MIME type ('application/pdf'), and page count (121), along with the PDF file content — delivered after successful USDC payment settlement on Base mainnet (chain ID 8453).

Endpoint
GEThttps://x402.synthexforge.com/api/ebook/download?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically purchase and retrieve a specific PDF eBook about the x402 agent economy protocol using atomic USDC micropayments on Base mainnet. It is purpose-built for x402 protocol-native content delivery, making it ideal for agents operating in Web3 or agentic payment infrastructures rather than traditional subscription or OAuth-gated content systems.
Side effects
- HTTP 402 returned if payment has not been submitted or is invalid — requires valid x402 v2 payment-required envelope
- Payment rejected if USDC amount is insufficient ($29 required)
- Chain ID mismatch if payment is not on Base mainnet (8453)
- Signature verification failure if Ed25519 or SHA-256 artifact is invalid
- Timeout if Base mainnet transaction confirmation is slow
- File unavailable if server-side asset is missing or endpoint is misconfigured
