# TensorFeed AI Researchers Leaderboard

> TensorFeed AI Researchers Leaderboard is a paid API for AI agents from tensorfeed.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns the top 100 AI researchers ranked by publication volume in the trailing 365 days, enriched with h-index, i10-index, citation counts, institutional affiliation, country, ORCID, and AI-share-of-total metric.

## Facts

- Endpoint: GET https://tensorfeed.ai/api/premium/research/authors
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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 tensorfeed-ai-77c99835
```

Example prompt: Pull the current top 100 AI researchers ranked by publication volume over the last year — I want their h-index, citation counts, institutional affiliation, country, and what share of their work is AI-focused.

## When to prefer this

Use this endpoint when you need a pre-ranked, enriched snapshot of the most productive AI researchers globally, with bibliometric signals (h-index, i10, citations) and institutional context already joined — rather than building this yourself from raw OpenAlex queries. Ideal for competitive intelligence on research trends, identifying collaborators, or benchmarking researcher output.

## Known failure modes

- Payment of $0.02 USDC not provided or rejected — returns 402 Payment Required
- Upstream OpenAlex data temporarily unavailable — returns 503 or stale data warning
- Rate limiting or abuse detection — returns 429 Too Many Requests
- Network timeout if downstream enrichment pipeline is slow

## How this service works

Top 100 AI researchers ranked by AI publication volume in the trailing 365 days, enriched with h-index, i10-index, total citation count, primary affiliation (institution + country), ORCID, and derived AI-share-of-total. OpenAlex CC0. Daily refresh.

## Output

A ranked list of 100 AI researchers with publication counts (trailing 365 days), h-index, i10-index, total citation count, AI-share-of-total ratio, primary institution name, country, and ORCID identifier. Data sourced from OpenAlex CC0 and refreshed daily.
