Batch Dependency Levels is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

How this service works
Batch Dependency Levels: Batch Dependency Levels topologically groups bounded jobs into executable dependency levels from bounded caller-supplied values without an external provider. Call Batch Dependency Levels before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Dependency Levels as versioned deterministic JSON. Pric…
Output
Returns a versioned deterministic JSON object containing the jobs grouped into ordered dependency levels (waves/tiers), along with counts of jobs per level, normalized job values, and a versioned result contract — enabling downstream tools or agents to execute groups in parallel where safe and sequentially where required.
Example use cases
Pipeline stage ordering for CI/CD
“I've got a list of build tasks — compile, test, lint, deploy, and a few others — and they all have prerequisites. Can you group them into dependency levels so I know which stages can run in parallel and in what order the rest need to go?”
Data pipeline execution planning
“I have 30 ETL jobs where some jobs need the output of others before they can start. Can you sort them into topological dependency levels so I can schedule the independent ones together and queue the rest in the right order?”
Pre-flight check before handing off to downstream tool
“Before I send this batch plan to the execution engine, can you organize these jobs into dependency levels so the downstream tool gets a properly ordered, structured plan it can follow without conflicts?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/batch-dependency-levels?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, versioned topological sort of a job batch before handing the plan to a downstream execution engine or tool with a strict ordering contract. It is ideal when jobs have dependency relationships that must be resolved into parallel-safe execution waves, and when you need a structured, normalized result with counts rather than building your own graph sort logic.
Side effects
- Circular dependency detected — jobs form a cycle with no valid topological ordering
- Input array exceeds maximum of 256 jobs — request rejected
- Individual job object exceeds 128 properties limit
- Malformed job objects that cannot be parsed
- Missing or empty jobs array in the request body
- Payment failure via x402 protocol — call not processed
