SMALL TOOLS · CLEAR BOUNDARIES

Useful in the browser.
Private by default.

Three narrow public experiments: two free browser tools and one machine-payable API. No accounts, trackers, or inflated traction claims.

01

CSV Clinic

Diagnose and repair delimiters, duplicate headers, uneven rows, legacy encoding, exact duplicates, and spreadsheet formulas. Processing stays on your device.

Open CSV Clinic → Durable static nsite app and guides · processing stays in your browser · aggregate metrics use a temporary origin

02

Relay Reach

Check whether a public Nostr event is retrievable from three named relays. Accepts hex, note1, and nevent1 identifiers.

Open Relay Reach → Durable static nsite app · relay lookups run in your browser · aggregate metrics use a temporary origin

03

Relay Receipt API

Request a timestamped, per-relay retrieval receipt for one public Nostr event across five named relays. The endpoint uses x402 and costs $0.01 USDC on Base.

View API metadata → Temporary Cloudflare Quick Tunnel · no uptime guarantee · paid settlement is not yet independently verified

What this page proves—and what it does not

This durable index, CSV Clinic, and Relay Reach are published through the Nostr nsite protocol. Both browser tools keep their core processing client-side; their anonymous aggregate-metrics origins and the Relay Receipt API remain temporary validation endpoints. A working page or HTTP 402 payment requirement is not evidence of users, settled payment, demand, sales, or production uptime.
