> **For coding agents and LLMs:** This is one page from the Social Fetch docs (markdown export). For curated orientation and workflow guidance, start with [`/llms.txt`](https://www.socialfetch.dev/llms.txt); for agent onboarding and crawl rules, use [`/agents.txt`](https://www.socialfetch.dev/agents.txt); for the full endpoint list with links to pages like this one, use [`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt); for one platform's parameters and curls, use [`/llms-{platform}.txt`](https://www.socialfetch.dev/llms-tiktok.txt); use [`/llms.json`](https://www.socialfetch.dev/llms.json) when you need structured JSON for tool registration. ## This page - **On-site (HTML):** [https://www.socialfetch.dev/docs/api/v1/hackernews/users/username/comments/get](https://www.socialfetch.dev/docs/api/v1/hackernews/users/username/comments/get) - **Markdown (.mdx) URL:** [https://www.socialfetch.dev/docs/api/v1/hackernews/users/username/comments/get.mdx](https://www.socialfetch.dev/docs/api/v1/hackernews/users/username/comments/get.mdx) ## API base URL and authentication - **API origin (from OpenAPI `servers`):** `https://api.socialfetch.dev` - **Authentication:** send `x-api-key: sfk_...` on `/v1/**` routes unless the operation is explicitly anonymous (check OpenAPI `security`, the [API reference hub](https://www.socialfetch.dev/docs/api.mdx), [`/llms.txt`](https://www.socialfetch.dev/llms.txt), or [`/llms.json`](https://www.socialfetch.dev/llms.json) for each route). - **OpenAPI JSON:** [https://www.socialfetch.dev/openapi.json](https://www.socialfetch.dev/openapi.json) ## Recommended docs entrypoints (this site) - [Documentation overview](https://www.socialfetch.dev/docs.mdx) — top-level orientation (markdown). -

[`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt) — every documented operation with a direct link to that route's agent-readable markdown page (prefer this over parsing OpenAPI). -

[Errors](https://www.socialfetch.dev/docs/errors.mdx) — shared error envelope and HTTP status guidance. - [Credits](https://www.socialfetch.dev/docs/credits.mdx) — metering, `402`, and planning batch jobs. - Outcome semantics such as `found`, `not_found`, and `private` are documented in [Errors](https://www.socialfetch.dev/docs/errors.mdx) and on operation pages when present in the OpenAPI contract. ## Markdown docs convention - Every docs page has a markdown twin: append **`.mdx`** to the docs pathname (for example `/docs/quickstart` → `/docs/quickstart.mdx`). - Agents that send `Accept: text/markdown` on `/docs/**` HTML URLs may receive markdown directly (same URL, `Vary: Accept`). --- # List Hacker News user comments (https://www.socialfetch.dev/docs/api/v1/hackernews/users/username/comments/get) ## Summary List a Hacker News user's comments (newest first). **Tags:** `Hacker News` ## HTTP -

I'll send you a transcript someday if I can arrange it :)", "url": null, "score": null, "commentCount": null, "parentId": 35681160, "childIds": [], "dead": false, "deleted": false, "itemUrl": "https://news.ycombinator.com/item?id=35686379" } ], "page": { "page": 0, "pageSize": 3, "returned": 3, "hasMore": true, "nextPage": 1 } }, "meta": { "requestId": "req_01example_hackernews_user_comments", "creditsCharged": 1, "version": "v1" } } ``` ### Machine-readable error codes When an error JSON body is returned, it may include one of these `error.code` values (derived from the OpenAPI schemas for this operation; additional codes may exist at runtime): - `bad_request` ## Error handling & retries Interpret HTTP status codes using the descriptions below. Do not assume a JSON body unless the OpenAPI schema defines one for that status. - **400**: Invalid request **Retry:** Fix the request; retrying the same invalid payload will not help. - **401**: Missing or invalid API key **Retry:** Fix the API key first; retrying without changes will not help. - **402**: Insufficient credits **Retry:** Do not retry without resolving billing/credits (retrying the same request will not help). - **500**: Unexpected or billing error - **502**: Lookup could not be completed. **Retry:** May be transient; a few retries with backoff are reasonable. - **503**: Service temporarily unavailable; safe to retry with backoff. **Retry:** Usually safe to retry with exponential backoff and jitter. ### Suggested client defaults - Send the API key using the `x-api-key` header on every request. - On `503` (and sometimes `502`), retry with backoff; cap retries and surface a clear error to the user. - On `402`, surface an actionable billing message rather than blind retries. ## Examples ### TypeScript SDK ```typescript import { SocialFetchClient } from "@socialfetch/sdk"; const client = new SocialFetchClient({ apiKey: process.env.SOCIALFETCH_API_KEY!, }); const result = await client.hackernews.getUserComments({ username: "tptacek", }); if (!result.ok) { console.error(result.error); } else { console.log(result.value.data); } ``` ### Node.js ```javascript const response = await fetch( "https://api.socialfetch.dev/v1/hackernews/users/tptacek/comments", { headers: { "x-api-key": "YOUR_API_KEY" } } ); const data = await response.json(); console.log(data); ``` ### cURL ```bash curl "https://api.socialfetch.dev/v1/hackernews/users/tptacek/comments" \ -H "x-api-key: YOUR_API_KEY" ``` ### Python ```python import requests response = requests.get( "https://api.socialfetch.dev/v1/hackernews/users/tptacek/comments", headers={"x-api-key": "YOUR_API_KEY"}, ) data = response.json() print(data) ```
