Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/slack/%7B*path%7D/*When to prefer
Use this endpoint when an AI agent needs to call any Slack Web API method via a pay-per-call micropayment model without managing a dedicated Slack API integration or credentials directly. Prefer this over direct Slack API calls when operating in an x402-native agentic environment where USDC micropayments are the authentication/billing mechanism.
Side effects
- Invalid or expired Slack token returns Slack auth error (invalid_auth)
- Wrong Slack API path returns 404 or Slack not_found error
- Malformed request body returns Slack invalid_arguments error
- Payment failure returns 402 Payment Required before the request is forwarded
- Rate limiting by Slack returns ratelimited error
- Missing required Slack parameters returns missing_scope or missing_arguments
