Query Hacker News via an AI agent, paid per-request with USDC on Base.
What it does
This endpoint exposes a Questflow-hosted AI agent that answers questions about Hacker News (HN), the Y Combinator-run social news site focused on computer science and entrepreneurship. The agent accepts a natural-language prompt via a POST request and returns a text response. Payment is handled through the x402 protocol using USDC on the Base network, with a maximum charge of 0.10 USDC per request (100000 in raw units of the 6-decimal USDC contract 0x8335…2913).
The interface is minimal: send a JSON body with an "input" string field containing your question or instruction, and receive a JSON response with a "response" string field. The maximum timeout is 1200 seconds (20 minutes), suggesting the agent may perform non-trivial retrieval or reasoning before replying. There is no published OpenAPI spec, no dedicated documentation page, and no rate-limit information available.
Questflow is a platform for creating autonomous AI "clones" that operate across on-chain markets and other domains. This particular agent appears to be a publicly discoverable, pay-per-use agent focused on Hacker News content. Because no detailed docs or usage examples exist beyond the x402 challenge metadata, the exact scope of the agent's HN knowledge (live scraping, cached data, summarization, search, etc.) is unknown.
Capabilities
Use cases
- —Ask natural-language questions about Hacker News stories and discussions
- —Retrieve summaries or insights from HN front-page content
- —Integrate HN intelligence into automated agent workflows via x402 micropayments
- —Monitor tech and startup news programmatically
Fit
Best for
- —Agents that need on-demand Hacker News information without managing scraping infrastructure
- —Developers wanting pay-per-query access to HN content via crypto micropayments
- —Workflows that combine multiple x402 endpoints and need a tech-news data source
Not for
- —High-volume, low-latency HN data pipelines (20-minute max timeout, no bulk API)
- —Users who need free or fiat-billed access to Hacker News data
- —Applications requiring structured HN data (scores, comment trees, user profiles) rather than natural-language answers

Quality
Only the x402 challenge metadata and a brief description are available. There is no OpenAPI spec, no documentation, no usage examples, and no information about what HN data the agent actually accesses. The response example is entirely inferred.
Warnings
- —No OpenAPI spec or dedicated documentation found; /docs returns 404.
- —Agent capabilities (live scraping vs. cached data vs. LLM knowledge) are unknown.
- —Response example is fabricated for illustration; actual output format may differ.
- —Maximum timeout of 1200 seconds suggests potentially very slow responses.
- —No rate limits, SLA, or uptime guarantees documented.
