  Signal AI publishes no pricing at all — no price, no tier names, no included
  quota, no overage. The API product page (https://signal-ai.com/solutions/api,
  HTTP 200) ends in a "Request a demo" call to action, and the site-wide
  llms.txt Signal AI itself serves at https://signal-ai.com/llms.txt (HTTP 200)
  enumerates 45 pages with no pricing or plans page among them. API credentials
  are a Client ID / Client Secret pair "provided to you" (per the OpenAPI
  securityScheme description) rather than self-issued, which confirms
  sales-mediated onboarding: there is no signup flow that produces working
  credentials without a Signal AI contract. Recorded as an honest zero, not an
  omission.
