Delx Concurrency Cap
x402
Delx Concurrency Cap is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Clamps a desired worker concurrency value against a hard maximum limit and queue depth saturation signal, returning the safe allowed parallelism as deterministic JSON.

How this service works
Cap desired worker concurrency against a hard limit and queue depth signal — call when clamping desired parallelism against a hard worker limit. Use before side effects when composing multi-step agent jobs—the same loyalty/workflow demand band agents already pay for on Bazaar, but fully local. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of li…
Output
Returns deterministic machine-readable JSON containing the allowed (capped) concurrency value, reflecting the lesser of desired_workers and hard_cap adjusted for queue depth saturation. No state is stored and the result is computed locally and statelessly.
Example use cases
Throttle agent job before side effects
“Before I fan out my order-processing pipeline, clamp my desired 50 concurrent workers against a hard cap of 30 and a current queue depth of 120 — what's the safe parallelism to use?”
Preventing crawler over-provisioning
“I'm about to launch a web scraping job. I want 25 workers but my system hard limit is 15 and the queue depth is 80 — tell me the concurrency I should actually run at.”
Dynamic scaling check in orchestration loop
“My orchestrator loop wants to scale up to 10 workers, the hard cap is 8, and queue depth is 3 right now — run a concurrency cap check so I know how many to actually start.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/concurrency-capWhen to prefer
Use this endpoint when you need a lightweight, stateless, local computation to enforce a hard worker concurrency ceiling before executing side-effecting or resource-intensive steps in an agent pipeline. Prefer it over custom logic when you want deterministic, machine-readable output without any upstream API dependencies, state retention, or latency overhead. Ideal for multi-step agent workflows on Bazaar or similar orchestration systems where parallelism must be bounded cheaply.
Side effects
- Missing required fields (hard_cap, desired_workers, or queue_depth) returns a 4xx validation error
- Negative queue_depth value may be rejected as invalid
- Non-numeric inputs cause schema validation failure
- Payment not included or insufficient USDC via x402 results in 402 Payment Required
