Delx Commerce — Concurrency Cap Calculator
x402
Delx Commerce — Concurrency Cap Calculator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).
Computes the effective number of concurrent workers an agent should use, capping at a hard limit and signaling saturation based on queue depth

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 JSON object with the schema identifier (delx/util-concurrency-cap/v1), the enforced hard_cap, a boolean saturated flag indicating whether the queue signals overload, the current queue_depth, the desired_workers requested, and the computed effective_workers (the actual number of concurrent workers the agent should use, never exceeding hard_cap).
Example use cases
Throttling an overloaded agent fleet
“My agent fleet wants to spin up 50 workers but I've set a hard cap of 10 and my queue is already at 25 jobs deep — how many workers should actually be running right now, and am I saturated?”
Safe parallelism for a document pipeline
“I'm processing documents in parallel and want to use 20 workers, but my hard limit is 6 and I have 8 items backed up in queue — what's the effective worker count I should launch?”
Dynamic concurrency control for a web scraper
“My scraper wants to fire off 15 concurrent requests, my hard cap is 4, and the queue is currently empty — give me the effective concurrency ceiling and tell me if I'm hitting saturation.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/concurrency-cap?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or orchestration system needs a real-time, pay-per-use computation of safe worker concurrency — especially when you want a lightweight, stateless utility that enforces a hard ceiling and returns a saturation signal without maintaining any server-side state. Prefer this over building custom throttle logic when you want verifiable, per-call pricing in USDC with no signup friction.
Side effects
- Missing required fields (hard_cap, desired_workers, queue_depth) result in validation errors
- Negative queue_depth values may be rejected as invalid
- Payment failure via x402 protocol results in 402 response before computation
- Network timeout if the Base or Solana payment settlement is delayed
- Non-numeric input types for numeric fields cause schema validation failure
