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

tinyfish-fetch 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fetch.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.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TinyFish Fetch

Fetch one or more URLs via the TinyFish Fetch API. Returns rendered page content (markdown by default), optionally with screenshots, behind an optional proxy.

Requires: TINYFISH_API_KEY environment variable.

Pre-flight Check (REQUIRED)

Before calling the API, verify the key is present:

[ -n "$TINYFISH_API_KEY" ] && echo "TINYFISH_API_KEY is set" || echo "TINYFISH_API_KEY is NOT set"

If the key is not set, stop and ask the user to add it. Get one at https://agent.tinyfish.ai/api-keys. Do NOT fall back to other fetch tools.

Basic Fetch

curl -X POST "https://api.fetch.tinyfish.ai" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "urls": ["https://example.com"],
    "format": "markdown"
  }'

format accepts markdown (default), html, or screenshot.

Multiple URLs

curl -X POST "https://api.fetch.tinyfish.ai" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "urls": [
      "https://example.com",
      "https://example.org"
    ],
    "format": "markdown"
  }'

Proxy / Geo Targeting

curl -X POST "https://api.fetch.tinyfish.ai" \
  -H "X-API-Key: $TINYFISH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "urls": ["https://example.com"],
    "format": "markdown",
    "proxy_config": { "country": "US" }
  }'

Helper Script

scripts/fetch.sh <url> [<url> ...] [--format markdown|html|screenshot] [--country CC] wraps the curl call:

scripts/fetch.sh https://example.com
scripts/fetch.sh https://example.com https://example.org --format html
scripts/fetch.sh https://example.com --format markdown --country US

Response Shape

{
  "results": [
    {
      "url": "https://example.com",
      "status": 200,
      "content": "# Example Domain\n\nThis domain is for use…",
      "format": "markdown"
    }
  ]
}

Read results[].content for the rendered page. Screenshot format returns base64-encoded PNG data.

What ships with it

1 file 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.
