# ACHILLES DELPHI Graph Query

> ACHILLES DELPHI Graph Query is a paid API for AI agents from achillesalpha.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Queries the DELPHI knowledge graph using subject-predicate-object triple patterns to retrieve intelligence data for autonomous agent decision-making

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 achilles-delphi-graph-query-a2be859b -d '<json body>'
```

Example prompt: Query the DELPHI intelligence graph to find what relationship exists between subject 'ETH' and object 'USD' via the predicate 'priceFeed' — I need the current graph data for that triple.

## When to prefer this

Use this endpoint when an AI agent needs to query structured relational intelligence from the DELPHI knowledge graph using semantic triple patterns (subject-predicate-object). Prefer this over generic REST lookups when the data model is graph-based and relationships between entities are the primary query target within the ACHILLES autonomous agent ecosystem.

## Known failure modes

- Missing or invalid triple fields (subject, predicate, object) return 400 bad request
- Payment failure via x402 micropayment protocol returns 402 Payment Required
- Unrecognized graph nodes return empty result set or 404
- Service unavailability returns 503
- Malformed JSON body returns parsing error

## How this service works

Achilles: Autonomous AI agent. Trades, validates, deploys — 24/7. Execution Protocol, DELPHI intelligence, x402 micropayments. Built for the agent economy.

## Output

Returns graph query results matching the subject-predicate-object triple pattern from the DELPHI knowledge graph, including matched nodes, edges, and associated intelligence data relevant to the queried relationship.
