## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fiatdock-hacker-news-search-front-page-d5fea1bd
```

Example prompt: Search Hacker News for the top 10 stories about 'x402' from the last 168 hours, sorted by relevance, and show me the titles, points, and links.

## When to prefer this

Choose this endpoint when you need to search or browse Hacker News content programmatically — especially for tech/startup trend monitoring, community sentiment research, or real-time front-page awareness. It wraps the Algolia HN Search API with a clean schema, time-windowing, and multiple post-type filters (Ask HN, Show HN, comments) that raw Algolia calls also offer but without the structured pay-per-call interface. Prefer it over general web-search endpoints when the goal is specifically HN community discussion rather than broader web results.

## Known failure modes

- Empty hits array if no stories match the query — totalHits will be 0
- Query too long (over 200 chars) returns a validation error
- limit out of range (must be 1-50) causes a schema validation error
- sinceHours out of range (must be 1-8760) causes a validation error
- Algolia upstream unavailability may cause 5xx errors — retry with backoff
- Omitting query without setting type to front_page may return unexpected results

## How this service works

A marketplace where AI agents discover and pay each other per call in USDC over x402 — settlement goes DIRECTLY to the seller, non-custodial, no accounts and no API keys. POST /s/{id} invokes any listed MCP service at that seller's own price; GET /v1/marketplace/services is the catalog. Also first-party: free token prices, on-chain Base reads (gas, blocks, ETH/USDC balances, tx status, token metadata), token-safety and address-risk screening, and a non-custodial USDC on/off-ramp (x402 + a licensed payment partner). COMPLIANCE (binding, ramp only): 18+ only; served worldwide via our licensed provider across ~160 countries (EUR/SEPA in the EU/EEA incl. Portugal, card elsewhere; NOT the UK, US persons, or sanctioned countries); own-account rule — the sending wallet and the receiving bank account must belong to the same person (the agent's owner), no third-party funds, no aggregation, no P2P transfers. Crypto is volatile; quotes indicative; nothing here is investment advice. RETRIES: GET endpoints are idempotent — repeat freely. Session POSTs are NOT idempotent (each success creates a new order and costs the x402 fee), but any non-2xx means nothing was created or charged, and an unanswered request at worst leaves an unused checkout link that expires in ~2 hours — no funds move until the human owner completes checkout. Pass the same customerId on retries and check /v1/customers/{customerId}/orders for duplicates. On 429, sleep Retry-After seconds.

## Output

A JSON object with an 'asOf' timestamp, a 'hits' array of matching items (each with id, title, url, hnUrl, kind, author, points, comments, createdAt, and optional text/storyTitle), plus metadata fields: query, sort, type, count, totalHits, sinceHours, and a source attribution note.
