How this service works
API Gateway: Slack Web API
Output
Returns the raw Slack Web API JSON response for the proxied request — typically includes 'ok: true', message timestamp, channel ID, and any relevant Slack-specific metadata or error details if the call fails.
Example use cases
Example prompt
“Post a message to our #alerts Slack channel saying 'Deployment to production completed successfully at 3:45pm' — use the pay-per-call Slack gateway so we don't need to manage API keys.”
Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/slack/%7B*path%7DWhen to prefer
Choose this endpoint when an AI agent needs to call the Slack Web API without managing OAuth tokens or API keys, and is already operating in a USDC/x402 micropayment context. Ideal for serverless agents or automation workflows that need occasional Slack notifications without the overhead of credential management.
Side effects
- 402 Payment Required if USDC payment header is missing or insufficient
- Invalid Slack path results in 404 from underlying Slack API
- Slack API rate limiting returns 429 too many requests
- Malformed request body causes Slack API validation error
- Slack channel not found or bot not invited returns channel_not_found error
- Payment settlement failure causes gateway to reject the request
