Delx Commerce Batch Dependency Levels
x402
Delx Commerce Batch Dependency Levels is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Computes topological dependency levels (execution order tiers) for a batch of jobs, detecting cycles or missing dependencies.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a 'levels' array where each sub-array is a set of jobs that can execute in parallel at that tier, plus a 'cycle_or_missing' array listing any jobs involved in cycles or with unresolvable dependencies. Also includes an evidence object with input hash and a flag confirming no data retention.
Example use cases
CI pipeline stage ordering
“I have a bunch of build steps with dependencies on each other — can you work out what order they should run in and which ones can be parallelized, and let me know if there are any circular dependencies?”
Data pipeline task scheduling
“Here are my ETL tasks with their upstream dependencies. Can you group them into execution levels so I know which ones can run at the same time and which have to wait?”
Package install order resolution
“I have a list of packages that depend on each other — can you figure out the correct install order by tier and flag anything that's missing or circular?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/batch-dependency-levels?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compute execution tiers for a batch of interdependent jobs in a single call, especially when cycle detection and verifiable in-memory-only processing (no data retention) are important. Prefer it over custom graph logic when you want a pay-per-call, no-signup, cryptographically verifiable result delivered via x402 on Base or Solana.
Side effects
- Jobs array exceeds 256 items — request rejected
- Individual job object exceeds 128 properties — item rejected
- Malformed JSON body — 400 error
- Cycles detected — reported in cycle_or_missing field rather than erroring
- Missing dependency references — reported in cycle_or_missing field
- Payment failure via x402 — 402 response before processing
