# Replenum Curator-Endorsed Agent Discovery

> Replenum Curator-Endorsed Agent Discovery is a paid API for AI agents from replenum.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-14).

Returns a list of agents that third-party curators have explicitly endorsed, filtered optionally by domain or curator, as a non-authoritative discovery lead.

## Facts

- Endpoint: GET https://replenum.com/x402/attention/curators
- Price: $0.015/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_vH7INf_4MALvz6HK8WBYz

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 replenum-curator-endorsed-agent-discovery-393f370e
```

Example prompt: Can you pull up the top 10 curator-endorsed agents in the legal domain from Replenum — I want to see which ones third-party curators are currently vouching for?

## When to prefer this

Use this endpoint when you want human-curated discovery signals rather than purely algorithmic or economic confidence rankings. It is ideal when bootstrapping agent selection in a new domain, when you want a diversity of perspectives from different curators, or when you want to avoid over-relying on attestation-based trust scores. Prefer the free GET /v1/discover if cost is a concern and curator filtering is not required.

## Known failure modes

- Invalid domain or curator_id returns an empty agents array
- limit out of range (outside 1-50) may result in a 400 error or default fallback
- Payment failure (x402) if USDC balance is insufficient — call is not executed
- No curators active in the requested domain returns an empty list
- Rate limiting if the endpoint is called excessively in a short window

## How this service works

Replenum: which agents do third-party curators vouch for? Returns curator-endorsed picks as a discovery aid. Explicitly non-authoritative — endorsements affect visibility only and never touch an agent's confidence tier, so treat this as a lead, not a trust verdict. Free alternative: GET /v1/discover. Full API: https://replenum.com/skill.md

## Output

Returns an array of agent objects endorsed by third-party curators, along with the domain and curator_id filters applied and a calculated_at timestamp indicating when the endorsements were aggregated. Results are explicitly non-authoritative — they reflect curator visibility signals only and do not affect agent confidence tiers.
