# DYOR Network SPARQL Query API

> DYOR Network SPARQL Query API is a paid API for AI agents from api.dyor.network, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Executes SPARQL SELECT queries against a crypto knowledge graph RDF triple store, returning structured results for entities, relationships, and properties in the crypto domain

## Facts

- Endpoint: GET https://api.dyor.network/api/sparql
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/dyor-network-sparql-query-api-14962fd0
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3I-8-6dOkNORFY1gatOZG

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 dyor-network-sparql-query-api-14962fd0
```

Example prompt: Run a SPARQL query against the DYOR crypto knowledge graph to find all tokens associated with Uniswap — something like SELECT ?token WHERE { ?token <relatedProtocol> <Uniswap> }

## When to prefer this

Use this endpoint when you need to traverse relationships and graph structure in the crypto knowledge graph using full SPARQL expressiveness — especially for multi-hop entity relationships, class membership queries, or pattern matching across RDF triples. Prefer over semantic search when you need precise, structured graph traversal rather than similarity-based retrieval, and over the time-series SQL endpoint when your query is about entity relationships rather than metric history.

## Known failure modes

- Malformed SPARQL syntax returns an error status with parse details
- Query references unknown predicates or classes not in the crypto knowledge graph ontology returning empty results
- Missing required 'query' parameter returns a 400-level error
- Query too broad or complex may timeout or return truncated results
- Payment failure (x402) if USDC balance insufficient

## Output

A JSON object containing: 'status' (success/error), 'variables' (array of SPARQL variable names from the SELECT clause), 'data' (array of result objects keyed by variable name), and 'count' (number of result rows returned)
