# Delx Commerce — GraphQL Operation Index

> Delx Commerce — GraphQL Operation Index is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).

Parses a GraphQL document and returns a structured index of all operations (queries, mutations, subscriptions) defined within it, including their names and types.

## 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 delx-commerce-graphql-operation-index-85fb6fb2 -d '<json body>'
```

Example prompt: Can you parse this GraphQL document and give me a list of all the operations defined in it — their names and whether each one is a query or mutation?

## When to prefer this

Use this endpoint when you need to programmatically enumerate all operations in a GraphQL document without running a full GraphQL server or schema introspection. It is ideal for CI tooling, code generation pipelines, document auditing, or any scenario where you need a quick structured inventory of GraphQL operations from a raw document string without setting up local tooling.

## Known failure modes

- Invalid or malformed GraphQL document string results in a parse error response
- Empty document string may return an empty operations array with zero count
- Very large documents may be truncated (truncated: true in response)
- Network or payment failure (x402 USDC payment not completed) results in 402 response

## How this service works

## Output

Returns a structured JSON object with schema identifier 'delx/util-graphql-operation-index/v1', a list of operations each containing a name and type (query/mutation/subscription), the total operation count, a flag indicating whether any anonymous operations are present, and a truncation flag indicating if the result was cut short.
