json-suite.underscoredone.com/json
Every agent and developer hits broken or confusing JSON. This tool handles the common headaches in one place: check whether JSON is valid with the exact error location, repair near-JSON with typos, pretty-print or minify, pull values out with a path expression, diff two documents, convert to and from YAML or CSV, produce a byte-stable canonical form for hashing, validate against a schema, and report size and structure. Same input, same output, no side effects.

On-chain payments
Payment shape (25 most recent sampled): 20 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 5 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-09-01: 26 payments. Last indexed day 2026-09-05: 4. Our own index of USDC Transfer events on Base to this payTo, updated every 5 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 28 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
