Authentication

Every request requires a Bearer token and namespace header:

Authorization: Bearer sk_live_...
X-Namespace: ns_production

API keys are scoped to an organization. Namespaces provide the authorization boundary — use separate namespaces for dev, staging, and production.

Secrets & LLM Keys

Store third-party API keys in an encrypted secrets vault. Secrets are encrypted at rest using Fernet symmetric encryption and are never exposed in API responses.

Manage Secrets

curl -X POST "https://api.mixpeek.com/v1/organizations/secrets" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "secret_name": "openai_api_key",
    "secret_value": "sk-proj-abc123..."
  }'

Bring Your Own Key (BYOK)

Use your own LLM API keys instead of Mixpeek’s default keys for cost control, higher rate limits, compliance, and independent key rotation. Supported providers: OpenAI, Anthropic, Google

Apply a Key to All LLM Operations

Set a key as the organization-wide default and it automatically applies to every LLM operation — extractors, retrievers, clustering, taxonomy inference, and manifest generation — with no per-stage configuration.

Store your key in the secrets vault

curl -X POST "https://api.mixpeek.com/v1/organizations/secrets" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "secret_name": "openai_api_key",
    "secret_value": "sk-proj-abc123..."
  }'

Set it as the org-wide default for that provider

curl -X PATCH "https://api.mixpeek.com/v1/organizations" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "default_llm_credentials": {
      "openai": "openai_api_key"
    }
  }'

Configure defaults for multiple providers at once:

{
  "default_llm_credentials": {
    "openai": "my_openai_key",
    "anthropic": "my_anthropic_key",
    "google": "my_gemini_key"
  }
}

In Studio, toggle “Use as default LLM key” when creating a secret to automatically apply it org-wide for the detected provider.

Override a Key on a Specific Stage

Set api_key directly on a retriever stage, extractor, or cluster config using {{secrets.name}} template syntax to override the org-wide default for that operation only:

{
  "parameters": {
    "provider": "openai",
    "model": "gpt-4o-mini",
    "api_key": "{{secrets.openai_api_key}}"
  }
}

Credential Resolution Order

Per-resource api_key / {{secrets.name}} — explicit key on a specific stage or extractor
Organization default — set once via default_llm_credentials, applied everywhere
Mixpeek platform keys — used when no custom key is configured (usage charged to your Mixpeek account)

Values in default_llm_credentials are secret names, not raw API keys. Keys are encrypted at rest, never returned in API responses, decrypted on-demand per LLM call, and isolated per organization with no cross-tenant leakage.

Document Access Control

Apply row-level security to documents with ACL rules. Filter results by user roles or attributes at query time without changing retriever logic. Document ACL API →

Webhooks

Subscribe to events like batch.completed, document.created, or alert.triggered:

curl -X POST "https://api.mixpeek.com/v1/webhooks" \
  -H "Authorization: Bearer $MIXPEEK_API_KEY" \
  -H "X-Namespace: $NAMESPACE_ID" \
  -H "Content-Type: application/json" \
  -d '{
    "webhook_name": "batch-notify",
    "url": "https://example.com/webhook",
    "events": ["batch.completed", "batch.failed"]
  }'

Webhook API →

Manifests

Declare your entire namespace configuration as code — buckets, collections, retrievers, taxonomies — and apply it in one request:

# Export current state
curl "https://api.mixpeek.com/v1/manifest/export" \
  -H "Authorization: Bearer $MIXPEEK_API_KEY" \
  -H "X-Namespace: $NAMESPACE_ID"

# Apply a manifest
curl -X POST "https://api.mixpeek.com/v1/manifest/apply" \
  -H "Authorization: Bearer $MIXPEEK_API_KEY" \
  -H "X-Namespace: $NAMESPACE_ID" \
  -H "Content-Type: application/json" \
  -d @manifest.json

Use POST /v1/manifest/diff to preview changes before applying. Manifest API →

Lineage & Audit Traces

Every document links back to its source, and every retriever execution produces an auditable trace.

Document Lineage

Track how a document was created — which object it came from, which collection processed it, and what features were extracted:

curl "https://api.mixpeek.com/v1/documents/$DOCUMENT_ID/lineage" \
  -H "Authorization: Bearer $MIXPEEK_API_KEY" \
  -H "X-Namespace: $NAMESPACE_ID"

Returns the full decomposition tree: source object → batch → extracted documents. Use this to trace any search result back to the original file.

# Get all documents derived from a source object
curl "https://api.mixpeek.com/v1/objects/$OBJECT_ID/derived" \
  -H "Authorization: Bearer $MIXPEEK_API_KEY" \
  -H "X-Namespace: $NAMESPACE_ID"

Lineage API →

Retriever Execution Traces

Every retriever execution captures a full trace — which stages ran, what scores were produced, which documents were dropped and why:

curl "https://api.mixpeek.com/v1/retrievers/$RETRIEVER_ID/executions/$EXECUTION_ID" \
  -H "Authorization: Bearer $MIXPEEK_API_KEY" \
  -H "X-Namespace: $NAMESPACE_ID"

A trace includes:

Which retriever version and config were used
Each stage’s input parameters, output set, scores, and latency
Which feature URIs and collections were consulted
Which filters matched and which documents were eliminated
The final result set with per-document provenance

Traces are replayable — if a model version or taxonomy changes, you can compare results against historical executions. Execution API → · Explain API →

Storage Tiering

Documents automatically tier across storage levels based on access patterns:

Tier	Backend	Use case
Hot	Qdrant (in-memory)	Frequently queried data
Warm	S3 Vectors	Occasional queries, lower cost
Cold	S3 raw	Archival, rare access
Archive	Metadata-only lineage	Compliance retention

The same feature URI resolves across all tiers — no application code changes needed.

Environment Branching

Clone namespaces to create isolated environments for testing:

curl -X POST "https://api.mixpeek.com/v1/namespaces/$NS_ID/clone" \
  -H "Authorization: Bearer $MIXPEEK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "namespace_name": "staging-branch" }'

Branched namespaces share no state with the source — safe for experimentation. Clone API →
