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

developer-utilities-get-base64 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 10d 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.

What it actually says

Endpoint

GET https://requiems.xyz/v1/technology/qr/base64

Generate QR Code

Generate a QR code for any string and return a base64-encoded PNG. Configurable size and error correction level.

Parameters

Name Type Required Location Description
data string yes query The string to encode into the QR code (URL, text, or any string).
size integer no query Output image size in pixels (width and height). Min 50, max 1000. Defaults to 256.
recovery string no query Error correction level: low, medium, high, or highest. Higher levels allow more of the QR code to be damaged while still scanning.

Request Example

GET /v1/technology/qr/base64?data=https%3A%2F%2Frequiems.xyz&size=256&recovery=medium

Response Example

{
  "data": {
    "image": "iVBORw0KGgoAAAANSUhEUgAAAQAAAAEACAYAAABccqhmAAAA...",
    "width": 256,
    "height": 256
  },
  "metadata": {
    "timestamp": "2026-01-01T00:00:00Z"
  }
}

Response Fields

Field Type Description
image string Base64-encoded PNG image of the QR code
width integer Image width in pixels, equal to the requested size
height integer Image height in pixels, equal to the requested size

Errors

  • undefined 400 — data query parameter is missing
  • undefined 422 — size is outside 50–1000 or recovery is not one of the valid values
  • undefined 401 — Missing or invalid API key

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.
