pinata

A set of helper scripts for storing files and JSON documents on IPFS through Pinata. IPFS is a content-addressed network where stored items are identified by a content hash called a CID.

In plain words
What is it for?
Use it to test access, upload files, pin JSON metadata, pin an existing CID, or unpin content using Pinata credentials.
Why use it?
It avoids manually constructing Pinata API requests and provides commands for authentication, uploading, pinning existing content, and removing pins.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pinata scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/_common.sh, scripts/auth-test.sh, scripts/pin-by-hash.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says

Pinata

Use Pinata to pin content to IPFS.

This skill ships with small scripts (in scripts/) that wrap the Pinata API with reasonable defaults. Prefer PINATA_JWT auth.

Setup

Auth (recommended):

  • Set PINATA_JWT to a Pinata JWT (Bearer token).

Optional (legacy-only, not supported by all endpoints):

  • Set PINATA_API_KEY and PINATA_API_SECRET (some older endpoints accept these).

Optional endpoint overrides:

  • PINATA_API_URL (default: https://api.pinata.cloud)
  • PINATA_UPLOAD_URL (default: https://uploads.pinata.cloud)

Quickstart

Run these from the Pinata skill directory (seeded to ~/.lemon/agent/skill/pinata by default):

Test auth:

./scripts/auth-test.sh

Upload a file (Pinata v3 uploads API):

./scripts/upload-file.sh ./path/to/file.png --network private --name file.png

Pin a JSON document (wraps your JSON as pinataContent):

./scripts/pin-json.sh ./metadata.json --name "metadata.json"

Pin an existing CID (by hash):

./scripts/pin-by-hash.sh bafy... --name "my-cid"

Unpin:

./scripts/unpin.sh bafy...

Notes

  • These scripts print raw JSON responses (so you can pipe into jq if you want).
  • For very large uploads, resumable uploads, or folder uploads, consider Pinata’s official tooling and docs: https://docs.pinata.cloud/
Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pinata is a skill published in the GitHub repository z80dev/lemon (129 stars, last pushed 3d ago), licensed MIT. It adds 20 tokens to every session and 445 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
