# EU CORDIS Research Projects Search API

> EU CORDIS Research Projects Search API is a paid API for AI agents from 4yearcycle.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Search and filter EU-funded research projects from the CORDIS database by topic, country, programme, and funding amount

## Facts

- Endpoint: GET https://4yearcycle.com/x402/eu-grants
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/eu-cordis-research-projects-search-api-07584c36

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 eu-cordis-research-projects-search-api-07584c36
```

Example prompt: Search the EU CORDIS database for up to 50 Horizon Europe projects related to 'battery recycling' coordinated in Germany or the Netherlands with a minimum total cost of 1,000,000 EUR.

## When to prefer this

Use this endpoint when you need structured, machine-readable data about EU-funded research projects from the official CORDIS database, especially when filtering by topic, country, or funding size. Prefer this over general web search when you need authoritative grant data with metadata like funding amounts, start dates, and coordinator countries. Best suited for research discovery, competitive intelligence on EU funding, or building datasets of Horizon Europe projects.

## Known failure modes

- No projects match the given filters — returns count 0 and empty projects array
- Invalid country code format returns a validation error
- max parameter above 200 is silently capped at 200
- Topic keyword yields no results if phrasing differs from CORDIS records
- Programme filter with non-HORIZON value returns empty or unfiltered results

## How this service works

Interactive Bitcoin 4-year halving cycle chart on a polar disc. Live price, 200W MA, Mayer Multiple, RSI, MACD, Pi Cycle and optional paid cycle projections.

## Output

Returns a JSON object with a count of matched projects and an array of project records, each containing the project title, acronym, CORDIS URL, full objective text, start date, total cost in EUR, coordinator country, funding programme, project status, and attribution text for the CORDIS data source.
