An agent makes hundreds of calls you never see.
Fluiq judges every one of them.
It chooses tools, chains steps, reads whatever the retriever returns, and hands work to other agents. Fluiq scores those decisions against criteria you set. It blocks the unsafe ones before they reach the model, and fails your build when quality drops.
Block attacks before they reach your model
A full suite of server-side scanners runs on every request. It catches jailbreaks, PII and secret leaks, and attacks injected through your tools, knowledge base, and other agents, not just the user message. Patterns are maintained server-side and updated without SDK releases. Everything fails open, so a scanner error never breaks your app.
- PII & secrets: cards, SSNs, IBANs, emails, names, provider API keys, high-entropy tokens
- Prompt attacks: injection, jailbreak, and instruction-override patterns
- RAG poisoning & indirect injection: retrieved docs and tool outputs scanned across the trace tree
- Tool misuse: exfiltration through tool arguments, plus allowlist enforcement
- Multi-agent trust: cross-agent injection and trust-boundary escalation across the DAG
- Images and other media are scanned alongside the text
- Included on every plan, starting with 1,000 scans a month on Free

Full trace visibility across every LLM call
Every token, latency, and cost attributed to the exact agent node that spent it. Streaming traces, cost anomaly alerts, and per-model breakdowns, without changing how you write code.
- Per-node token attribution
- p50 / p95 / p99 latency tracking
- Multi-agent runs render as real DAGs: fan-outs, joins, and loops across LangGraph, CrewAI, and Google ADK
- Real-time trace streaming
- Import existing history from LangSmith, Langfuse, Phoenix, or Braintrust
Catch the bad run before your users do
LLM-as-judge scores every response server-side, and agentic evaluation judges the whole run: which tools it picked, whether the path served the goal, and how agents coordinated. Pin real runs into golden datasets and re-run the same judges before you ship a prompt or model change.
- Six judge metrics: hallucination, faithfulness, relevance, toxicity, coherence, completeness
- Agentic eval scores tool selection, trajectory-vs-goal, and multi-agent coordination across the run's DAG
- Borderline verdicts convene a multi-model judge jury; every member's score and reasoning is kept for audit
- Block mode raises FluiqEvalError before a failing response reaches your users
- Golden datasets pin the entire trajectory (steps, tools, MCP calls, media) and stay evaluable after retention ends
- Diff any two dataset runs to see exactly what regressed, and gate CI on it
- Version and deploy prompt templates, then promote any prompt to a custom judge by slug

How it works
Three functions. Production-ready in minutes.
01
fluiq.instrument()
Patches every LLM call automatically. Traces, costs, and latency start flowing to your dashboard.
02
fluiq.secure()
Pre-call attack detection blocks bad prompts. Post-call scanning redacts PII from stored traces.
03
fluiq.eval()
LLM-as-judge scores every response. Warn or block based on your quality thresholds.
import fluiq, openai
# 1. Wire instrumentation once at startup
fluiq.instrument(api_key="fl_...")
# 2. Block attacks before they reach the model (Team+)
fluiq.secure(mode="block")
# 3. Score and gate every response (all tiers)
fluiq.eval(
thresholds={"hallucination": 0.8, "relevance": 0.75},
mode="warn", # "block" raises FluiqEvalError
)
# Your code is unchanged from here
client = openai.OpenAI()
response = client.chat.completions.create(
model="gpt-4o",

Framework-agnostic
Works with the stack you already use.
Fluiq patches at the function-call level, not the framework level. Any Python function that hits an LLM or vector database becomes a traced span with one decorator.
from fluiq import instrument, trace
instrument(api_key="fl_...")
@trace
def answer_question(question: str) -> str:
docs = vector_store.search(question, k=5)
return llm.invoke(prompt(question, docs))
# Every call is now:
# Traced with cost + latency
# Security-scanned
