1. Connect

Connect: Add the server at https://api.spritefetch.dev/mcp to your agent's MCP config, or send requests to https://api.spritefetch.dev. No key needed. Your agent gets three tools: search, get_asset, and download.

// No key needed. Optional: a free API key raises limits.
{ "mcpServers": { "spritefetch": { "url": "https://api.spritefetch.dev/mcp" } } }

2. First search

First search: Ask your agent for an asset in plain words, or call the search endpoint. Check the license fields in the response before you ship.

# No key needed. Optional: a free API key raises limits.
search({ "query": "pixel-art fox run", "license_spdx": "CC0-1.0" })
GET https://api.spritefetch.dev/v1/search?q=pixel-art+fox+run&license_spdx=CC0-1.0

Sample response (trimmed)

{ "results": [{
  "id": "asset_…", "version": 1, "metadata_revision": 2,
  "license_spdx": "CC0-1.0", "attribution_required": false, "verification_status": "reviewed",
  "slicing": { "frame_width": 153, "frame_height": 139, "grid_cols": 6, "grid_rows": 2, "margin": 0, "spacing": 0,
    "pivot": { "x": 76.5, "y": 139 },
    "animations": [{ "name": "run", "frames": [0,1,2,3,4,5,6,7,8,9,10,11], "fps": 24, "loop": true }] },
  "file_url": "https://api.spritefetch.dev/files/asset_…/v/1/orange-fox-run.png",
  "sha256": "5164efbe…",
  "json_url": "https://api.spritefetch.dev/v1/assets/asset_…/v/1/"
}], "next_cursor": "…" }

3. Optional: API key

Optional: Add a free API key for higher limits (60/min and 2,000/day instead of 30/min and 500/day). Send it as Authorization: Bearer <API_KEY>.

Limits are planning defaults.

# Optional: a free API key raises limits (planning defaults: 60/min, 2,000/day per key).
curl -H "Authorization: Bearer <API_KEY>" "https://api.spritefetch.dev/v1/search?q=knight&license_spdx=CC0-1.0"

{ "mcpServers": { "spritefetch": { "url": "https://api.spritefetch.dev/mcp", "headers": { "Authorization": "Bearer <API_KEY>" } } } }

Limits (planning defaults)

	Anonymous	With free API key
Search + metadata	30 requests/min, 500/day per IP	60 requests/min, 2,000/day per key
CC0 public file URLs	No key needed, not counted	No key needed, not counted

Before you ship, check each asset's license fields and include its attribution string where required.

Stable URLs

/assets/{id}/v/{version}/ never changes. /assets/{id}/latest/ may move. id = asset_ + 12 lowercase chars, immutable. Files live at /files/{id}/v/{version}/{filename} and are byte-for-byte immutable.

Parity: UI / REST / MCP

Task	Website	REST	MCP tool
Search	/search?q=	GET /v1/search	search
Asset details + license	/assets/{id}/v/{version}/	GET /v1/assets/{id}/v/{version}/	get_asset
Download	Download button	public file_url (CC0) or GET …/download	download

Errors (examples)

• 401: invalid key (search needs no key).
• 429: limit reached (planning defaults: 30/min and 500/day per IP; 60/min and 2,000/day per key).
• 410 Gone: a rejected asset (never served publicly).
• Checksum mismatch: re-download, then report.
