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.
