PayloadIQ for Cursor

The full PayloadIQ JSON & API toolkit, inside Cursor — convert payloads to typed code, decode tokens on hover, and scan for secrets, then hand the AI clean, structured context instead of a raw blob.

Runs entirely in your editor. Nothing is uploaded — no telemetry, no account.

Cursor runs VS Code extensions, so PayloadIQ works in it natively — install the .vsixbelow and you're set. An Open VSX listing (Cursor's marketplace) is on the way.

Install · v2.0.0
Same build as VS Code. Install the .vsix directly, or grab the source ZIP.

What it does

Tighter context for Cursor's AI
A raw payload is nested, untyped and token-heavy. Convert it once into a typed interface, a Zod schema that documents every field, or compact output (TypeScript · Zod · Go · Rust · Kotlin · Prisma · SQL · JSON Schema · GraphQL · YAML · CSV · mock data · fetch()) and Cursor stops guessing the shape of your data.
Convert from selection or clipboard
Convert JSON to… (Ctrl/Cmd+Alt+J) on a selection or whole file, or “Paste JSON as…” straight from the clipboard into the cursor.
Inline hovers
Hover a JWT, Base64 string or Unix timestamp to decode it in place — no command, no leaving the editor.
Local secret scanner
Inline squiggles flag leaked credentials in JSON and .env files before they reach a commit or a prompt, plus a full Scan for Secrets & PII report.
Explain · quality · tokens
Plain-English Explain Payload, a Schema Quality score, and an LLM token estimate — handy before you feed data to the model.
Everyday JSON
Format / Minify / Sort Keys in place, Copy Field Paths, CodeLens on JSON files, and a status-bar readout.
