caesar-search (Python)

Official Python SDK for the Caesar search API — web search with provenance, built for agents.

Quickstart

# pip install caesar-search    (or: uv add caesar-search)
from caesar_search import Caesar

client = Caesar()  # requires CAESAR_API_KEY (get one at app.trycaesar.com)
results = client.search("rust async runtime comparison", max_results=5)
doc = client.read(results.results[0].doc_id, query="which runtime is fastest")
client.feedback("result_helpful", search_id=results.search_id, doc_id=doc.doc.doc_id)

Clients

• Caesar — synchronous; AsyncCaesar — same surface with async/await. Both support context managers.
• Methods: search(), read() (doc_id or URL; start_char= continues truncated reads), feedback().
• Responses are typed pydantic v2 models generated from the public OpenAPI spec; provenance fields (doc_id, search_id, capture_id, canonical/source URLs, crawl dates) are preserved verbatim.
• client.with_raw_response.search(...) returns the raw httpx.Response.
• Retries: 429/5xx with capped exponential backoff honoring Retry-After (max_retries= to tune, 0 to disable).
• Config: api_key= / CAESAR_API_KEY is required for the public API; base_url= / CAESAR_BASE_URL may point at a self-hosted deployment.

Errors

CaesarError → APIConnectionError / APITimeoutError and APIStatusError (with .status_code, .code, .message, .request_id) → AuthenticationError (401/403), MissingAPIKeyError (local missing_api_key preflight), RateLimitError (429).
