# DYOR Crypto Knowledge Graph SPARQL Query

> DYOR Crypto Knowledge Graph SPARQL Query is a paid API for AI agents from kg.dyor.network, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-10).

Execute SPARQL SELECT queries against a 586K+ entity crypto knowledge graph covering protocols, tokens, chains, investors, governance, and DeFi data

## Facts

- Endpoint: GET https://kg.dyor.network/api/sparql?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10

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 kg-dyor-network-d648239e
```

Example prompt: Run a SPARQL query against the DYOR crypto knowledge graph to find all protocols on Ethereum with TVL greater than $100M, returning their names and TVL values.

## When to prefer this

Use this endpoint when you need precise, structured RDF graph traversal over the DYOR crypto knowledge graph — ideal for complex multi-hop relationship queries (e.g. investor → protocol → chain), filtering by ontology classes, or joining entities across sources like DefiLlama, CoinGecko, CryptoRank, and Snapshot. Prefer over semantic search endpoints when you know exact entity URIs or ontology predicates.

## Known failure modes

- Invalid SPARQL syntax returns a 400 error
- Query timeout for overly complex or unindexed traversals
- Missing required 'query' parameter returns validation error
- Unsupported SPARQL features (e.g. UPDATE, CONSTRUCT) may be rejected
- Payment failure (402) if x402 payment not provided
- Rate limiting if query volume exceeds plan limits

## How this service works

Query the DYOR crypto knowledge graph using SPARQL. Covers 586K+ entities across 8,200+ protocols, tokens, chains, investors, governance, and DeFi data from DefiLlama, CryptoRank, CoinGecko, TokenTerminal, Snapshot, and Tally.

## Output

A JSON object containing a status field, an array of variable names, an array of result rows (each as a key-value object matching the SELECT variables), and a total count of matching results.
