Delx Commerce — Retry Budget Plan Calculator
x402
Delx Commerce — Retry Budget Plan Calculator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).
Computes an exponential backoff retry schedule given base delay, growth factor, max attempts, and an optional delay ceiling.

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 containing a labeled schedule array where each entry shows the attempt number and the delay in milliseconds before that attempt, plus total_delay_ms (sum of all delays) and max_attempts. Includes an advisory note that the caller owns the actual retry policy.
Example use cases
API retry plan for flaky service
“I need a retry schedule for calling an unreliable third-party API — start with a 200ms delay, double it each attempt, allow up to 6 retries, and never wait more than 10 seconds between tries.”
Agent task orchestration backoff
“My AI agent sometimes hits rate limits. Give me a backoff plan starting at 500ms with a growth factor of 2, capped at 8000ms, for up to 8 retry attempts so I know the exact delays to use.”
Low-latency retry budget for real-time systems
“I'm building a real-time pipeline that needs fast retries — plan me a schedule with a 50ms base delay, factor of 1.5, max 4 attempts, and a hard ceiling of 500ms per delay.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/retry-budget-plan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or automated system needs a precise, pre-computed retry delay schedule rather than implementing backoff logic inline. Ideal for agents that need to externalise retry policy calculation, audit the full schedule before executing, or share a consistent backoff plan across multiple subsystems. Costs $0.003 USDC per call via x402, so best used when the computed schedule will be reused across many retries rather than recalculated per attempt.
Side effects
- Invalid factor value (e.g. negative or zero) may cause unexpected schedule output
- max_attempts outside 1–20 range may be rejected or clamped
- Missing required fields may result in a 400 error or default values being applied
- Payment failure via x402 protocol results in no response being returned
