Building Production AI Agents on ZeroDB

This guide walks through the six steps every production agent on the ZeroDB platform should follow: get a scoped credential, isolate memory, sanitize external content, call inference, handle errors gracefully, and clean up after the run.

By the end you will have a complete working Python example that chains all six steps.


Prerequisites

  • A ZeroDB account with an API key (sk_...)
  • Python 3.10+ with httpx installed (pip install httpx)
  • Base URL: https://api.ainative.studio
Auth header quick reference

API keys (sk_*) go in X-API-Key. Authorization: Bearer is for JWT tokens only. Mixing these returns a 401.


Step 1 — Get a Scoped API Key

Your root ZERODB_API_KEY grants full platform access. Never give it to an agent. Instead, create a short-lived scoped key for every agent run.

POST /api/v1/auth/keys

FieldTypeRequiredDescription
namestringyesHuman-readable label (1–128 chars)
ttl_secondsintegernoSeconds until expiry — omit for non-expiring
scopesarrayyesPermissions: <service>:<permission>[:<namespace>]

Valid services: zerodb, inference, memory, file, agent, mcp

import os, httpx

ROOT_KEY = os.environ["ZERODB_API_KEY"]
BASE = "https://api.ainative.studio"

resp = httpx.post(
f"{BASE}/api/v1/auth/keys",
headers={"Authorization": f"Bearer {ROOT_KEY}", "Content-Type": "application/json"},
json={
"name": "research-agent-run-42",
"ttl_seconds": 3600, # 1-hour key — expires automatically
"scopes": [
"memory:write:session/run-42",
"memory:read:session/run-42",
"inference:call",
],
},
)
resp.raise_for_status()
agent_key = resp.json()["key"] # store immediately — shown once only
key_id = resp.json()["id"] # save for revocation at the end

Why scoped keys matter: A scoped key limits blast radius. If the key is leaked or the agent is hijacked via prompt injection, the attacker can only read and write to session/run-42 — not your entire project or other users' data.

The key value is returned once only. Store it in a variable or secret manager — it cannot be retrieved again.

Key rotation

Rotate keys on a schedule. For high-risk workflows (external network access, file writes) use daily rotation. For lower-risk read-only agents, weekly rotation is acceptable.


Step 2 — Set Up Memory Namespacing

ZeroDB memory is persistent and shared. Every write requires a namespace — there is no silent global fallback.

NamespaceWhen to use
session:<uuid>Ephemeral per-run memory. Always start here.
project:<uuid>Shared across sessions for a project. Promote verified facts here.
globalPlatform-wide. Never write untrusted or agent-generated content here.

The disposable memory pattern

Isolate the agent run in a session namespace, do the work, then promote verified outputs and discard the session. Use Python try/finally so cleanup runs even if the agent crashes.

import uuid, httpx, os

session_id = str(uuid.uuid4())
session_ns = f"session:{session_id}"
agent_headers = {"X-API-Key": agent_key, "Content-Type": "application/json"}

try:
# Store incoming context in the isolated session namespace
httpx.post(
f"{BASE}/api/v1/public/memory/v2/remember",
headers=agent_headers,
json={
"content": "Research target: renewable energy storage trends 2026.",
"namespace": session_ns,
"memory_type": "episodic",
"importance": 0.8,
"tags": ["task-context"],
},
).raise_for_status()

# Recall memories within the namespace
recall = httpx.post(
f"{BASE}/api/v1/public/memory/v2/recall",
headers=agent_headers,
json={
"query": "What is the research target?",
"namespace": session_ns,
"limit": 5,
},
)
memories = recall.json()["results"]

# ... run the agent, produce verified_facts ...

# Promote only verified outputs to project namespace
for fact in verified_facts:
httpx.post(
f"{BASE}/api/v1/public/memory/v2/remember",
headers=agent_headers,
json={
"content": fact,
"namespace": "project:energy-research",
"memory_type": "semantic",
"importance": 0.9,
"tags": ["verified"],
},
).raise_for_status()

finally:
# Always clean up session namespace — even if agent crashed
httpx.delete(
f"{BASE}/api/v1/public/memory/session/{session_id}",
headers=agent_headers,
)
Never write untrusted content to global

Emails, web scrapes, uploaded files, and third-party API responses are untrusted. Write them to session:<id> first, inspect them (see Step 3), then promote only clean content to project: or global. Writing unvalidated content to global poisons every agent that shares that namespace.


Step 3 — Quarantine External Content

Before passing any content arriving from outside your control boundary to the agent, run it through the quarantine endpoint. This strips prompt injection payloads, zero-width Unicode, hidden script tags, and base64 blobs.

POST /api/v1/public/security/quarantine

FieldTypeRequiredDescription
contentstringyesRaw text to sanitize (max 500,000 chars)
content_typestringyespdf_extract, html, ocr, or markdown
strip_linksbooleannoStrip external links (default true)

What gets stripped:

  • Zero-width and bidi Unicode (U+200B, U+202A–U+202E)
  • HTML comment injection (<!-- ... -->)
  • Script tags (<script>...</script>)
  • Base64 blobs (60+ char heuristic)
  • External links (when strip_links: true)
def quarantine(raw: str, content_type: str = "html") -> str:
resp = httpx.post(
f"{BASE}/api/v1/public/security/quarantine",
headers=agent_headers,
json={
"content": raw,
"content_type": content_type,
"strip_links": True,
},
)
resp.raise_for_status()
result = resp.json()

if not result["safe_to_use"]:
# script_injection or base64_blob found — do not proceed
raise ValueError(
f"Content failed quarantine. Threats: {result['threats_detected']}. "
"Flag for human review."
)

return result["sanitized"]


# Usage: quarantine before storing in memory or passing to inference
raw_email = "<email body from external sender>"
clean_content = quarantine(raw_email, content_type="html")

Response fields:

FieldDescription
sanitizedCleaned text — pass this to your agent or store in memory
threats_detectedArray: hidden_unicode, html_comment_injection, script_injection, base64_blob, external_links
stripped_countTotal items removed
safe_to_usefalse when script_injection or base64_blob found — require human review

Integration flow:

External content (email / web scrape / uploaded file)


POST /api/v1/public/security/quarantine

├─ safe_to_use=false ──► Reject / escalate to human review

└─ safe_to_use=true ──► Store in session namespace, pass to inference
warning

Never pass content where safe_to_use is false to a privileged agent context. The threats detected are designed to manipulate agent behavior (prompt injection). Flag the content and require a human to review it.


Step 4 — Call Inference

The platform exposes two compatible endpoints. Choose based on which SDK you are already using.

FormatEndpointUse when
Anthropic Messages APIPOST /v1/messagesUsing Anthropic SDK or anthropic-version header
OpenAI Chat CompletionsPOST /api/v1/chat/completionsUsing OpenAI-compatible client or openai library

Both accept X-API-Key for authentication.

Anthropic-compatible endpoint

resp = httpx.post(
f"{BASE}/v1/messages",
headers={
"x-api-key": agent_key,
"anthropic-version": "2023-06-01",
"Content-Type": "application/json",
},
json={
"model": "claude-sonnet", # stable alias — do not use provider IDs directly
"max_tokens": 1024,
"system": "You are a research assistant. Summarize findings concisely.",
"messages": [
{"role": "user", "content": clean_content},
],
},
)
resp.raise_for_status()
answer = resp.json()["content"][0]["text"]

OpenAI-compatible endpoint

resp = httpx.post(
f"{BASE}/api/v1/chat/completions",
headers={"X-API-Key": agent_key, "Content-Type": "application/json"},
json={
"model": "llama-3.3-70b", # routed to NIM automatically
"messages": [
{"role": "system", "content": "You are a research assistant."},
{"role": "user", "content": clean_content},
],
},
)
resp.raise_for_status()
answer = resp.json()["choices"][0]["message"]["content"]

Model aliases

Always use AINative aliases — never hard-code provider model IDs, which change when providers retire models.

Claude models (Anthropic endpoint):

AliasResolves to
claude-sonnetclaude-sonnet-4-20250514
claude-haikuclaude-haiku-4-5-20251001
claude-opusclaude-opus-4-20250514

Non-Claude models (OpenAI-compatible endpoint, routed via NIM or Cerebras):

AliasProviderSpeed
qwen-coder-32bNIMGeneral coding
llama-3.3-70bNIMGeneral purpose
llama-4-maverickNIMMultimodal
deepseek-v4-flashNIMFast reasoning
mistral-large-3NIMInstruction following
llama3.1-8bCerebrasUltra-fast (2000 tok/s)
qwen3-235b-cerebrasCerebrasLarge, fast

You can also prefix any alias with ainative/ — the router strips it automatically (e.g. ainative/claude-sonnet).

Streaming

Both endpoints support "stream": true and emit SSE:

with httpx.stream(
"POST",
f"{BASE}/v1/messages",
headers={"x-api-key": agent_key, "anthropic-version": "2023-06-01"},
json={
"model": "claude-haiku",
"max_tokens": 512,
"stream": True,
"messages": [{"role": "user", "content": "Count to 5"}],
},
) as r:
for line in r.iter_lines():
if line.startswith("data: "):
print(line[6:])

Step 5 — Handle Errors

All endpoints return machine-readable error_code values in the JSON body. Parse the code, not the HTTP status, to drive agent retry logic.

Error codes

CodeHTTPMeaningAgent action
AUTH_001401Invalid credentialsFail immediately — do not retry
AUTH_002401Token expiredRefresh token, retry once
AUTH_003401Token invalid or revokedFail immediately
AUTH_004401Session expiredRe-authenticate
PERM_001403Insufficient permissionsFail — key lacks required scope
PERM_004403Subscription requiredFail — upgrade plan
API_404404Resource not foundFail — verify ID
API_429429Rate limitedBackoff with Retry-After header
INSUFFICIENT_CREDITS402Account out of creditsFail — top up credits
RATE_LIMIT_EXCEEDED429Endpoint-level rate limitBackoff exponentially

The next_action field

Many responses include a next_steps object that tells your agent what to do next. Surface it or use it to drive decision trees:

{
"id": "mem_abc123",
"next_steps": {
"action": "recall",
"suggestion": "Memory stored. You can now recall it by meaning using /recall.",
"endpoint": "POST /api/v1/public/memory/v2/recall"
}
}

Retry with exponential backoff

import time, httpx

def call_with_backoff(url: str, headers: dict, payload: dict, max_attempts: int = 5):
for attempt in range(max_attempts):
resp = httpx.post(url, headers=headers, json=payload)

if resp.status_code == 429:
wait = int(resp.headers.get("Retry-After", 2 ** attempt))
time.sleep(wait)
continue

if resp.status_code in (401, 402, 403):
# Auth and billing failures will not resolve on retry
error = resp.json()
raise PermissionError(
f"{error.get('error_code', resp.status_code)}: {error.get('detail', 'access denied')}"
)

if resp.status_code >= 500:
if attempt < 3:
time.sleep(2 ** attempt)
continue
resp.raise_for_status()

resp.raise_for_status()
return resp

raise RuntimeError(f"Max retry attempts reached for {url}")

Retry rules:

  • 429 — exponential backoff, always respect the Retry-After header
  • 401 / 403 — fail fast, retrying will not help
  • 402 — do not retry, add credits first
  • 500 / 503 — retry up to 3 times with backoff
Do not poll in tight loops

Rapid request bursts exhaust the DB connection pool (20 connections per instance). Always use backoff. Tight polling against production endpoints can take down the service for all users.


Step 6 — Clean Up

After the agent run, delete the session namespace and revoke the scoped key. This prevents stale data accumulation and ensures the key cannot be reused if it leaks later.

# 1. Delete session namespace
httpx.delete(
f"{BASE}/api/v1/public/memory/session/{session_id}",
headers=agent_headers,
).raise_for_status()

# 2. Revoke scoped key (use root key for this call)
httpx.delete(
f"{BASE}/api/v1/auth/keys/{key_id}",
headers={"Authorization": f"Bearer {ROOT_KEY}"},
).raise_for_status()

print("Agent run complete. Session and key cleaned up.")
MCP cleanup

If you are using zerodb-memory-mcp, call zerodb_clear_session(session_id="...", confirm=True) instead of the REST endpoint. The confirm: true flag is required for all destructive MCP operations.

Pre-Deploy Checklist

Before shipping any agent to production:

Check
Use a scoped API key — never the root key[ ]
Set ttl_seconds on all agent keys[ ]
Use session:<uuid> namespace for untrusted workflows[ ]
Quarantine all external content before agent ingestion[ ]
Never pass content with safe_to_use: false to a privileged agent[ ]
zerodb_clear_session or DELETE called at end of every run[ ]
Error handling uses backoff — no tight polling loops[ ]
X-API-Key used for sk_* keys, Authorization: Bearer for JWTs only[ ]
Model IDs use AINative aliases, not provider-specific IDs[ ]
No secrets stored in agent memory or logs[ ]
