Details

A color conversion and manipulation utility for working with colors across multiple formats used in web development, graphic design, and user interface design. It features a smart color parser that accepts input in any common format including hexadecimal codes with or without hash prefix in both short and long forms, RGB functional notation, HSL functional notation, comma-separated RGB values, and over 140 CSS named colors like coral, steelblue, and papayawhip. Format conversion functions translate between hex, RGB, and HSL color spaces with full component extraction for programmatic use. Color manipulation operations include finding complementary colors by rotating 180 degrees on the color wheel, darkening and lightening by adjustable percentages through lightness modification, inverting colors by subtracting each channel from 255, and adjusting saturation up or down for more vibrant or muted tones. The random color generator produces full color specifications across all formats, while the palette generator creates harmonious color schemes using color theory principles including analogous, complementary, and evenly-distributed hue rotations with subtle saturation and lightness variations. All operations return results in multiple formats simultaneously for immediate use in CSS, design tools, or further processing.

This tool supports credit-based access for external agents using AgentAddress identities or standard crypto wallets. External agents should use the External Agent API to buy credits with x402 and invoke this tool.

1. Buy Credits

Purchase credits via x402 payment (500 credit minimum, 100 credits = $1).

# Request payment requirements (returns 402 + PAYMENT-REQUIRED header)
curl -i -s -X POST "https://www.agentpmt.com/api/external/credits/purchase" \
  -H "Content-Type: application/json" \
  -d '{ "wallet_address":"0xYOUR_WALLET", "credits": 500, "payment_method":"x402" }'

# Sign the EIP-3009 authorization, then retry with signature header
curl -s -X POST "https://www.agentpmt.com/api/external/credits/purchase" \
  -H "Content-Type: application/json" \
  -H "PAYMENT-SIGNATURE: <base64-json>" \
  -d '{ "wallet_address":"0xYOUR_WALLET", "credits": 500, "payment_method":"x402" }'

2. Create a Session Nonce (nonce used in signed balance/invoke)

curl -s -X POST "https://www.agentpmt.com/api/external/auth/session" \
  -H "Content-Type: application/json" \
  -d '{ "wallet_address":"0xYOUR_WALLET" }'

3. Invoke This Tool

Sign the message with your wallet (EIP-191 personal-sign), then POST to the invoke endpoint.

# Sign this message (wallet MUST be lowercased):
# agentpmt-external
# wallet:0xyourwallet...
# session:<session_nonce>
# request:<request_id>
# action:invoke
# product:694de6f7ecea2b5619a17bdc
# payload:<sha256(canonical_json(parameters))>

curl -s -X POST "https://www.agentpmt.com/api/external/tools/694de6f7ecea2b5619a17bdc/invoke" \
  -H "Content-Type: application/json" \
  -d '{
    "wallet_address": "0xYOUR_WALLET",
    "session_nonce": "<session_nonce>",
    "request_id": "invoke-uuid",
    "signature": "0x<signature>",
    "parameters": {
