Technical writing

Deep dives on verifiable document memory, x402 payments, cryptographic proofs, and building trustworthy AI agents.

Where are DocImprint technical deep-dives?

The DocImprint blog at /blog publishes 1,500+ word posts on x402 micropayments, Merkle citation proofs, evidence bundle architecture, MCP integration, and chain-of-custody for legal workflows — with runnable curl examples.

Which blog post explains verifiable document memory?

Start with /blog/verifiable-document-memory-architecture for architecture tradeoffs vs RAG, /blog/tamper-evident-evidence-bundles for bundle concepts, and /blog/merkle-proofs-document-citations for cryptographic citation grounding.

Which post covers x402 agent payments?

/blog/x402-http-payment-protocol explains HTTP 402 USDC flows on Base. /blog/x402-vs-api-keys compares wallet pay-per-call vs API key monthly credits.
