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) +``` +
