Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.00859 |
| Opus 5.5 | $0.00019 | $0.00344 |
| Sonnet 5.5 | $0.00010 | $0.00172 |
| Haiku 4.5 | $0.00005 | $0.00086 |
Grade A, and why
etsy-api scanned grade A with 0 findings 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 2mo ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Etsy Open API v3 Skill
Use this skill when you need to read or modify Etsy shop resources using Etsy Open API v3, including:
- Listings: create drafts, update listing metadata, upload images/files, manage videos, update inventory/offerings
- Shop: retrieve/update shop settings, shop sections, shipping profiles, processing profiles, return policies
- Receipts/orders: retrieve receipts and transactions, post-purchase workflows
- Taxonomy: seller/buyer taxonomy nodes and properties
- Webhooks: create/rotate endpoints, subscribe to events, verify signatures
This skill package includes reference docs and scripts to make correct, rate-limit-aware requests.
Authentication model (critical)
Etsy uses:
- API key header on all requests
- OAuth 2.0 user tokens (Authorization Code + PKCE) for scoped/private endpoints
Required headers
All requests must include:
x-api-key: <ETSY_KEYSTRING>:<ETSY_SHARED_SECRET>
Scoped endpoints additionally require:
Authorization: Bearer <ETSY_OAUTH_USER_ID>.<ETSY_OAUTH_ACCESS_TOKEN>
Note: Etsy’s Bearer token format includes the numeric user id, a dot (
.), and then the access token.
See:
references/02_authentication.mdreferences/03_request_standards.md
Rate limits (must follow)
Etsy enforces per-application rate limits:
- QPS (queries per second)
- QPD (queries per day) using a rolling 24-hour sliding window
When you receive HTTP 429, honor the retry-after header and use exponential backoff.
See:
references/04_rate_limits.md
Scripts you can run (code_execution)
All scripts are under skills/etsy-api/scripts/.
1) Make requests safely
Use the CLI to perform an arbitrary request with proper headers:
python skills/etsy-api/scripts/etsy_cli.py request GET /v3/application/listings?state=active
You can pass a body for POST/PUT with --data (JSON) or --form (x-www-form-urlencoded).
2) OAuth helpers (PKCE + token exchange)
Generate a PKCE verifier/challenge and an authorization URL:

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.
- 2mo ago First seen · 113 lines · 48 tokens per session scan A fe601779de73
etsy-api is a skill published in the GitHub repository J-DTurner/etsy-api-skill (6 stars, last pushed 9mo ago), licensed MIT. It adds 48 tokens to every session and 859 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
