> FiatDock RSS/Atom Feed Reader is a paid API for AI agents from fiatdock.com, paid per call via x402, $0.0022/call, status unknown (last checked 2026-10-12).

Fetches and parses any public RSS or Atom feed URL, returning structured items with titles, links, summaries, authors, and timestamps

## 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-rss-atom-feed-reader-a3e23da1
```

Example prompt: Pull the latest 10 headlines from https://hnrss.org/frontpage and show me the titles, links, and when they were published.

## When to prefer this

Use this endpoint when you need to read and parse a known RSS or Atom feed URL into structured data, especially in a pay-per-call agent workflow without API key management. It handles both RSS and Atom formats, normalizes the output schema, and refuses non-feed URLs without charging. Prefer it over general web scrapers when the source is a proper syndication feed.

## Known failure modes

- URL points to a non-feed page — request is refused and not charged; response names any linked feed if discoverable
- Feed URL is unreachable or returns an error — call fails with an appropriate HTTP error
- Invalid URL format — validation error before charge
- Feed has no items — returns empty items array
- Malformed or non-standard feed XML — may return partial data or parsing error

## 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 containing the feed's metadata (title, description, format, source URL, timestamp) and an array of up to 100 items, each with an ID, link, title, author, summary, and published/updated timestamps. Includes a count of items returned and a truncated flag if the feed had more items than the limit.
