Summary

Company name inputs on /analyze and /analyze/batch are not validated beyond basic FastAPI type checks. Malformed or excessively long inputs can cause downstream errors in SERP lookups, LLM calls, and storage paths.

What to Do

  • Disallow special characters in company names (allow only alphanumeric, spaces, hyphens, ampersands, and periods)
  • Enforce a minimum length of 2 characters and a maximum of 100 characters
  • Return a clear 422 Unprocessable Entity with a descriptive message on validation failure
  • Use Pydantic validators (@field_validator or Annotated with StringConstraints) so validation is automatic and reflected in the OpenAPI schema

Acceptance Criteria

  • Company names with disallowed characters are rejected with 422 and a clear error message
  • Names shorter than 2 or longer than 100 characters are rejected
  • Valid names (including names with spaces, hyphens, ampersands) are accepted
  • Validation is enforced on both single and batch analysis endpoints
  • Unit tests cover: too short, too long, special chars, valid edge cases
  • OpenAPI schema reflects the new constraints
