• POST /api/x402-testnet/brief — 調べた内容を出典つきで1枚にまとめた報告（調査1件） (free)
• POST /api/x402-testnet/code-review — コードの問題点と修正案（根拠つき・検証済み） (free)
• POST /api/x402/data-clean — Cleans a CSV/TSV/JSON table: removes duplicate and empty rows, trims whitespace, and returns the cleaned CSV with before/after quality checks and per-column stats. Call it before analysing or importing messy tabular data. Input: {"data": "<csv text>"}. (0.5 USDC on Base)
• POST /api/x402/brief — Returns a one-page research brief with cited source URLs, key findings and open gaps for a question. Call it when an agent needs a sourced answer instead of an unsourced guess. Input: {"question": "..."} (5-400 chars, any language). (1 USDC on Base)
• POST /api/x402/code-review — Reviews source code and returns line-numbered findings with severity and a concrete fix, combining deterministic static rules (eval, SQL concat, secrets, shell injection) with an AI review. Call it before merging or running untrusted code. Input: {"code": "...", "language": "javascript"}. (0.75 USDC on Base)
• POST /api/x402/diff — Return the line-level diff between two texts as added/removed/unified hunks with counts. Use it to review a patch, compare two API responses, or decide whether two documents actually differ before spending tokens on them. (0.01 USDC on Solana)
• POST /api/x402/url-meta — Fetch one public URL and return machine-readable page metadata: HTTP status, title, meta/og description, canonical URL, language, link count and a short text sample. Honest 4xx/5xx statuses are returned as data, not as errors. Use it for link previews, source triage and citation checks. (0.03 USDC on Base)
• POST /api/x402/csv-json — Convert tabular data between CSV/TSV and a JSON array of objects, in either direction, with detected delimiter and typed columns. Use it when a tool returns CSV but your pipeline needs JSON (or the reverse) and you do not want to run a parser yourself. (0.02 USDC on Base)
• POST /api/x402/regex — Apply one regular expression to a text blob on the server and return every match with its index and capture groups. Deterministic, so the same input always returns the same answer. Useful for log triage, field extraction and validation at scale. (0.01 USDC on Base)
