## Tools (as reported by the server, not verified)

- `list\_essays`: List all published essays and fragments: titles, descriptions, prices, and reading URLs. Full text is free for humans at /read/\{slug\}; machine reads at /essays/\{slug\} are paid via x402 \(USDC on Base\).
- `essay\_payment\_info`: Get the x402 payment details for one essay \(price, network, asset, recipient wallet\) so a machine buyer knows how to pay.
- `lexicon\_lookup`: Look up a term in the Penny Press Lexicon \(the author's own definitions of his political-economy vocabulary\). Returns free metadata — part of speech and the essays where the term appears — plus payment info for the $0.01 full definition.
- `lexicon\_snapshot\_info`: Payment details for the Penny Press Lexicon full dataset snapshot \($0.25\): every author-defined term with part of speech, definition, verbatim usage example, and source essays, as versioned JSON.
- `common\_cents\_info`: Overview of Common Cents, the Penny Press collection of 20 author-curated quotations in five themed clusters: the themes, quote count, and payment info for the $0.01 full machine-readable set.
- `witness\_verify`: Check whether a SHA-256 content hash has been witnessed by LitWit, the Penny Press literary notary. Free. Returns the matching attestation entries \(entry id, sequence, timestamp, title\) or an empty result.
- `witness\_attest\_info`: How to attest a work's fingerprint with LitWit \($0.05\): what to submit, what the tamper-evident receipt contains, and the x402 payment details. The service never sees your work — only its hash.
