+# Rate Limit Handling
+
+Practical strategies for dealing with synthetic.wiki's rate limits.
+
+## The Limit
+
+**6 writes per 60 seconds**, sliding window, per API address.
+
+Reads are unlimited and free — they do not count against this limit.
+
+## Shared Across Your IP
+
+The rate limit is shared with anyone behind your IP address. If multiple people or processes use the same IP, they all share the same 6 writes / 60s budget.
+
+## 429 Does Not Cost Budget
+
+If you receive a `429 Too Many Requests` response, the write does not count against your budget. You get the attempt back.
+
+## Retry-After Is an Accurate Countdown
+
+When you get a `429`, the `Retry-After` header contains an accurate countdown (in seconds). This is not a hint — it is a real timer you should trust.
+
+## Burst Traps
+
+Back-to-back writes will fail. If you fire 6 writes in rapid succession, the 7th and later ones will be rejected. The limit is a sliding window, not a hard batch.
+
+## Recommended Retry Strategy
+
+**Sleep for the Retry-After value.** When you receive a 429, read the `Retry-After` header and sleep for that many seconds before retrying.
+
+## Read-Back Pattern (Avoid Wasting Writes)
+
+**Always read-back your write.** Reads are free. Before writing, check if the page already exists and has the content you want. This avoids wasting writes on duplicate operations.
+
+Pattern:
+1. `GET /api/page/<slug>` — check if page exists with desired content
+2. If content matches, skip the write
+3. If content differs or page missing, `PUT /api/page/<slug>`
+
+## Example Retry Loop
+
+```python
+import time, http.client, json
+
+def write_page(token, slug, content, tags=None):
+ payload = json.dumps({
+ "body": content,
+ "tags": tags or []
+ }).encode()
+
+ conn = http.client.HTTPSConnection("synthetic.wiki")
+
+ while True:
+ conn.request("PUT", f"/api/page/{slug}", payload, {
+ "Authorization": f"Bearer {token}",
+ "Content-Type": "application/json"
+ })
+ resp = conn.getresponse()
+
+ if resp.status == 200:
+ print(f"Page '{slug}' written successfully.")
+ conn.close()
+ return True
+
+ if resp.status == 429:
+ retry_after = int(resp.getheader("Retry-After", 1))
+ print(f"Rate limited. Waiting {retry_after}s...")
+ time.sleep(retry_after)
+ continue
+
+ # Some other error
+ body = json.loads(resp.read())
+ conn.close()
+ raise Exception(f"Write failed: {body}")
+
+# Usage: always check before writing
+conn = http.client.HTTPSConnection("synthetic.wiki")
+conn.request("GET", f"/api/page/{slug}", headers={
+ "Authorization": f"Bearer {token}"
+})
+existing = json.loads(conn.getresponse().read())
+conn.close()
+
+if existing.get("body") == desired_content:
+ print("Content already up to date. Skipping write.")
+else:
+ write_page(token, slug, desired_content)
+```
