Stars, forks, open issues, license and last push for a GitHub repo via https://api.github.com/repos/<owner>/<repo>

Test endpoint for verifying x402 payment integration end to end. Returns a static greeting in the Agent Tollbooth standard response envelope. Not a data product — use it to smoke-test your x402 client for $0.001 before calling our compliance endpoints.

Check up to 32 JSON argument values against a closed, declared scalar tool contract: types, required fields, code-point length and exact safe-integer bounds. Rounded fractions/underflow are not integers. Returns unknown fields and mismatches. No remote references, arbitrary patterns, tool execution or MCP conformance certification.

diff scan for planned tool calls: compares before and after snippets and flags destructive, network or secret-related actions.

Markdown to HTML. POST a Markdown file; the response is an HTML FRAGMENT — CommonMark plus GitHub tables, no <html> wrapper and no stylesheet. It does not sanitize: raw HTML in the input passes through, so sanitize before rendering untrusted output into a page.

Deterministic syntax validation — does this JSON/YAML/TOML/Python/regex parse? Valid/invalid + error location from the canonical parser. For long source use POST. Free sample, no payment required: GET /play/syntax

Exact structured diff. mode=text -> unified diff + line counts; mode=json -> an RFC 6902 JSON Patch (RFC 6901 pointers) that round-trips a->b; mode=words -> inline word-level opcodes. For large inputs use POST. Every answer signed. Free sample, no payment required: GET /play/diff

Translate .po Files Without Breaking Gettext — Translates the messages of a gettext PO file (.po) into another language and returns the whole file, so msgfmt and the app that loads it accept it. Only the msgstr values change. msgid, msgid_plural and msgctxt, every comment line, flags, the header (apart from its Plural-Forms line), obsolete entries and all placeholders such as %s, %d, %(name)s, {name} and %1$s come back exactly as they were. Entries with plural forms get exactly the number of ms…

Sandboxed JS execution ($0.05) — run a JavaScript snippet in an isolated child process (64MB heap cap, no network, no filesystem) and get the result plus captured logs. Pragmatic sandbox, not a hardened enclave. Toll: $0.05 USDC on Base or Solana.
