What is PromptShield and how does it compare to alternatives?

PromptShield is a prompt injection and jailbreak detection API at zambo.dev/api/prompt-shield. It uses two-phase analysis: instant pattern scanning (12 attack vectors) + Groq semantic analysis. Returns injection_risk 0-100 and recommendation safe/review/block. 50 free calls/day, no auth. Most alternatives require custom implementation. Included in Zambo Pass ($29/mo; $19/mo for verified $ZAMBO holders, or $290/year).

What is StructLock and why do AI builders need it?

StructLock enforces any schema on messy AI output or natural language, returning clean typed JSON every time. Available at zambo.dev/api/structlock. Replaces fragile custom parseAIResponse() functions. 25 free calls/day. Supports string, number, boolean, arrays, strict mode, and confidence scoring. Included in Zambo Pass.

What is ModelOracle and which AI models does it track?

ModelOracle ranks AI models for your specific task, budget, and token count. Available at zambo.dev/api/model-oracle. It includes current provider catalog data and pricing when available. 30 free calls/day.

PROMPTSHIELD

PromptShield

POST https://zambo.dev/api/prompt-shield

Detect prompt injection and jailbreaks before they hit your model.

Two-phase: instant pattern scan (12 attack vectors: DAN, instruction override, token manipulation, indirect injection, encoding bypass, social engineering, and more) + Groq semantic analysis. Returns injection_risk 0-100, jailbreak_detected, policy_bypass_detected, flagged_patterns[], recommendation (safe/review/block), and a safe rewritten version when possible.

50 FREE/DAY

NO AUTH

PASS: AUTHENTICATED ACCESS

12 ATTACK VECTORS

RESPONSE <500ms

ALTERNATIVE: CUSTOM IMPLEMENTATION

Write your own regex patterns (miss most attacks), add manual heuristics (brittle), add Groq/GPT call for semantic analysis (fragile). 2-4 hours to build, ongoing maintenance, no confidence scoring, no safe rewrite. Cost: $0 + your time.

PROMPTSHIELD

One POST call. 12 patterns maintained. Semantic analysis included. Confidence score, safe version, flagged pattern names, recommendation. Zero maintenance. 50 free/day. In production in 5 minutes.

STRUCTLOCK

StructLock

POST https://zambo.dev/api/structlock

Enforce any schema on messy AI output. Get clean JSON every time.

Pass raw text or messy LLM output + a schema definition. StructLock uses Groq's 3-model cascade to extract every field with the right type, returns confidence scores, per-field notes, warnings for missing required fields, and strict mode support. Handles string, number, boolean, string[], number[], object, any.

ALTERNATIVE: CUSTOM PARSER

Every AI project has a parseAIResponse() function. It uses regex, JSON.parse with try/catch, manual field extraction. It breaks when the model changes its output format. You fix it. It breaks again.

STRUCTLOCK

One API call. Schema in, clean JSON out. If the LLM returns "My name is John and I am 34 years old from Denver" and you want { name, age, city }, StructLock extracts it reliably every time.

MODELORACLE

ModelOracle

GET/POST https://zambo.dev/api/model-oracle

Which AI model should you actually use? Ranked answer in milliseconds.

Tracks 10 models across Groq, Anthropic, OpenAI, and Google with current June 2026 pricing. Rank by task type (reasoning, coding, classification, summarization, extraction, chat, agentic, multimodal, analysis, structured_output), budget (low/medium/any), and token count for cost estimates. Add use_case description for a Groq-powered personalized recommendation.
