100-word summary
SafePrompt launched a protection API that stops prompt injection attacks before they reach your language model. It catches over 95% of malicious prompts (jailbreaks, data extraction, code injection) in under 100 milliseconds with a single API call. Only 5% of requests need the full four-stage scan. The twist: when one customer blocks a new attack, every customer benefits within 24 hours through anonymized threat sharing. Free tier includes 1,000 requests monthly; beta pricing starts at $5. The bigger question is whether developers will finally treat prompt security like they treat SQL injection, or keep shipping vulnerable chatbots until a breach forces their hand.
