Reader clients 1.5.1

Download one executable and its matching checksum into the same folder. These are the exact 1.5.1 files served by our website, verified against source commit 651be3d and the published checksums. Requires Node 20.19+; no npm install or new account.

• CLI: reader-client.mjs and reader-client.mjs.sha256
• Local MCP adapter: reader-mcp.mjs and reader-mcp.mjs.sha256
• SHA256SUMS covers both executables and command-builder.js. Verify only your downloaded executable using its matching one-file checksum; checking the complete list requires all listed files.

Setup and shell-specific checksum commands: https://agent-data-tools.revmesh2074.workers.dev/guides/web-reading.md
Local MCP setup: https://agent-data-tools.revmesh2074.workers.dev/guides/local-mcp

An unpaid quote needs no key and never signs:

node reader-client.mjs quote https://example.com --format markdown

A purchase requires an existing funded Base wallet, explicit authorization and a cap:

node reader-client.mjs buy https://example.com --max-usdc 0.002 --format markdown

Supply X402_PRIVATE_KEY privately through the local process environment. Never put it in command arguments, URLs or public reports. Each buy can authorize one payment; stop and reconcile the request ID and receipt after an uncertain signed outcome. Do not automatically retry. The MCP adapter starts in quotes-only mode; buying requires explicit opt-in and a process budget.

The same clients support capped sitemap and Bitcoin fee-data calls. Static HTML, Markdown or plain-text reader input only; no JavaScript rendering, login or paywall access. Markdown source retains syntax with empty structured metadata. Version 1.5.1 corrects source-relative HTML links using linkBaseUrl. No source code or linked page is executed or fetched automatically.

These download checks are unpaid operator verification, not customer purchases or evidence of funded delivery. Checksums are published by the same operator and are not independent security signatures. API prices remain unchanged.
