# Ambolt RSS Feed Normaliser

> Ambolt RSS Feed Normaliser is a paid API for AI agents from api.ambolt.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

## 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 ambolt-rss-feed-normaliser-1e48d0cd
```

Example prompt: Fetch the BBC News RSS feed at https://feeds.bbci.co.uk/news/rss.xml and return the 10 most recent headlines with their summaries and published timestamps.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call, no-infrastructure way to turn any RSS or Atom feed URL into clean structured JSON — especially inside AI agent pipelines that need feed content without maintaining a dedicated feed parser. It also supports auto-discovery of feeds from plain web page URLs, making it useful when the exact feed URL is unknown.

## Known failure modes

- Invalid or unreachable URL returns an error; feed not found at the given address
- Web page supplied does not link to a discoverable feed; discovered flag will be false and items empty
- Feed exceeds maxItems limit; only newest items up to the limit are returned
- Feed format is non-standard or malformed; parsing may fail or return partial data
- Payment not included or insufficient; 402 Payment Required response

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

A JSON object containing feed-level metadata (title, description, link, language, format, detected feed URL, fetch timestamp) and an array of items (up to 200), each with an ID, URL, title, plain-text summary, published and updated timestamps, categories, and enclosure info. Also includes the total item count returned and a note about publisher licensing.
