## 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 particle-pro-podcast-guest-recommendations-1967e0ad
```

Example prompt: Pull the Particle Pro podcast pitch list for guest slug 'lex-fridman' — show me the top 10 recommended shows he hasn't appeared on yet, and include the 'via' context so I can see which of his existing shows are driving each recommendation.

## When to prefer this

Use this endpoint when you need a ready-made, signal-driven podcast pitch list for a specific guest — particularly when you want recommendations that are demonstrably related to shows the person has already appeared on, not just broad category matches. It is the right choice for PR professionals, speaker bureaus, and booking agents who need to justify outreach with data about why a show is a good fit. Prefer it over generic podcast search when the guest's existing appearance history should drive the ranking.

## Known failure modes

- Unknown or invalid guest ID/slug returns a 404 or empty result set
- Guest with no prior podcast appearances returns an empty recommendations list (no signal to rank from)
- Invalid cursor value causes pagination error
- Rate limiting or payment failure under x402 protocol returns 402 or 429
- Network timeout on large recommendation sets

## How this service works

List podcasts a guest could plausibly appear on next. Returns shows the person has NOT appeared on, ranked by how related they are to the shows the person HAS appeared on — the pitch list.

## Output

A paginated, ranked list of podcast shows the specified guest has not appeared on, ordered by relevance to their existing appearance history. When include=via is passed, each recommendation also carries the guest's own shows that drove the recommendation — actionable context for crafting a pitch.
