Palantir Rate Limits

Overview

Handle Foundry API rate limits with exponential backoff, request queuing, and monitoring. Foundry rate limits vary by endpoint and enrollment tier.

Prerequisites

• foundry-platform-sdk installed
• Understanding of HTTP 429 responses

Instructions

Step 1: Understand Foundry Rate Limits

Foundry rate limits are per-user and per-endpoint. Key limits:

Endpoint Category	Typical Limit	Burst
Ontology reads	100 req/s	200
Ontology writes (Actions)	50 req/s	100
Dataset reads	50 req/s	100
Search queries	20 req/s	50

Rate limit headers returned:

• X-RateLimit-Limit — max requests per window
• X-RateLimit-Remaining — requests left in window
• Retry-After — seconds to wait (on 429)

Step 2: Implement Retry with Backoff (Python)

import time
import random
import foundry

def retry_foundry_call(fn, *args, max_retries=5, base_delay=1.0, **kwargs):
    """Retry Foundry API calls with jittered exponential backoff."""
    for attempt in range(max_retries + 1):
        try:
            return fn(*args, **kwargs)
        except foundry.ApiError as e:
            if attempt == max_retries:
                raise
            if e.status_code not in (, , , ):
                  
            delay = base_delay * ( ** attempt) + random.uniform(, )
            retry_after = (e, , )
             retry_after:
                delay = (delay, (retry_after))
            ()
            time.sleep(delay)


employees = retry_foundry_call(
    client.ontologies.OntologyObject.,
    ontology=, object_type=, page_size=,
)
