Details

The Discord Webhook Tool enables AI agents to send rich, formatted messages directly to Discord channels through webhook URLs. It supports text messages with full Discord markdown formatting, custom username and avatar overrides, and rich embeds with titles, descriptions, fields, colors, images, and timestamps. The tool can upload up to 10 files per message with base64 encoding and reference them within embeds using the attachment:// syntax for seamless image display. Advanced features include mention controls to manage user/role pings, text-to-speech capabilities, and support for multiple embeds (up to 10) in a single message for complex notifications. Perfect for automation workflows, monitoring systems, chatbot integrations, and notification pipelines requiring formatted Discord output.

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" }'

Common Workflows

Automated Notifications — Send alerts from monitoring systems, CI/CD pipelines, or scheduled tasks to a Discord channel using a simple text message.
Formatted Reports — Use embeds with fields, colors, and timestamps to deliver structured data like daily summaries, analytics, or dashboards.
File Delivery — Attach generated reports (CSV, PDF, images) directly to Discord messages using base64-encoded file content.
Multi-Channel Broadcasting — Send the same message to multiple channels by calling the tool once per webhook URL.

Important Notes

You must provide at least one of content, embeds, or files in every send request.
The webhook_url must match the Discord webhook URL pattern. You can create webhooks in Discord under Channel Settings > Integrations > Webhooks.
Embed colors must be decimal integers, not hex strings. Convert hex to decimal (e.g., 0x0099FF = 39423).
File content must be valid base64-encoded data.
Discord limits: 2000 characters for content, 10 embeds per message, 25 fields per embed, 10 files per message.
The tts (text-to-speech) option will cause the message to be read aloud to users in the channel.
