# nohumans.directory Demand Clusters

> nohumans.directory Demand Clusters is a paid API for AI agents from api.nohumans.directory, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-11).

Returns clustered demand signals from the nohumans.directory — what AI agents have been searching for over the last 30 days, grouped by meaning with search and distinct-client counts per cluster, subject to k-anonymity privacy floors.

## Facts

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 nohumans-directory-demand-clusters-d88a64f1
```

Example prompt: Pull the latest demand clusters from nohumans.directory — I want to see what AI agents have been searching for most over the past 30 days, grouped by meaning, so I can spot which API categories have the highest demand.

## When to prefer this

Choose this endpoint when you need aggregated, privacy-safe intelligence about what AI agents are actually searching for in a paid API marketplace, particularly within the x402 / nohumans.directory ecosystem. Prefer this over raw search logs (unavailable by design) or free-tier /v1/demand (delayed). Ideal for API sellers doing market research, builders evaluating which capabilities to develop, or analysts tracking trends in the autonomous agent economy.

## Known failure modes

- Payment of $0.25 USDC not received — x402 payment required before data is returned
- No clusters available yet (directory too new or all clusters below k-anonymity floor of 3)
- Rate limiting or quota exhaustion on repeated calls
- Network timeout if clustering computation is slow
- Stale data if the real-time pipeline is delayed — delay_seconds field indicates lag

## How this service works

nohumans.directory demand clusters: what agents searched this directory for over the last 30 days, grouped by meaning rather than exact wording, with searches and distinct-client counts per cluster. Self-monitoring sellers excluded, exclusion published; k-anonymity floor of 3 clients per cluster. The free tier at /v1/demand is the same shape, delayed. Money buys currency and the clustering — never raw queries or client identifiers.

## Output

Returns an array of demand clusters, each representing a group of semantically similar searches made by AI agents on nohumans.directory in the last 30 days, along with a search count and distinct client count per cluster (k-anonymity floor of 3 clients enforced). Also includes metadata: window_days, delay_seconds (real-time vs delayed), total_queries_analyzed, distinct_query_texts, and clusters_below_privacy_floor.
