## 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 yodeler-data-api-news-search-f720560d
```

Example prompt: Search Yodeler's news message logs for 'airdrop' — show me up to 25 results from July 1st 2026 onward.

## When to prefer this

Choose this endpoint when you need to search through a corpus of real-time forwarded news messages by keyword or phrase, especially for crypto/financial news monitoring. It is ideal for agent workflows that need to find recent news about a specific topic, token, or event, and where per-query micropayment via x402 is acceptable. Prefer it over general web search when you want structured, timestamped message logs from curated news channels rather than open web results.

## Known failure modes

- Missing required 'q' query parameter returns a 400 error
- Query string shorter than 2 characters or longer than 128 characters is rejected
- Payment not provided or insufficient triggers an x402 payment-required response
- Invalid ISO-8601 format for 'since' parameter causes a 400 validation error
- Non-existent channel ID returns an empty result set
- Rate limiting or quota exceeded returns a 429 error

## How this service works

Query forwarded real-time news message logs from the database.

The `/v1/news` endpoint is designed to be monetized with x402 so clients can
pay per request before receiving message batches, while `/v1/news/quote`
and `/v1/news/availability` expose free previews for agent workflows.

Discovery metadata is available through `/openapi.json` and
`/.well-known/agent.json`, while `/v1/discovery` publishes the canonical
discovery index for marketplaces and agent registries.

Empty result sets are returned for free, and `/v1/news/channels` offers a
free source-channel catalog so buyers can explore before paying.

Agents can understand the tool contract,
payment flow, supported networks, and pricing model automatically.

## Output

Returns a JSON object with a list of matching news message items (each with ID, message text, snippet, channel name, source ID, and timestamp), a window showing oldest/newest match timestamps, match count, source count, license info, and payment metadata including asset, price, and network details.
