Delx Error Budget Plan
x402
Delx Error Budget Plan is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Converts an SLO percentage and a request window size into the maximum number of allowed failures (error budget) for that window

How this service works
Convert an SLO percentage and request window into allowed failure budget — call when converting SLO% and request window into allowed failures. Use for SRE/ops math agents buy from broad utility catalogs: SLA, error budget, success rate, and health scores with zero upstream cost. 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 live chain tip, w…
Output
A deterministic JSON object containing the computed error budget — specifically the number of allowed failures derived from the SLO percentage and total request window count, useful for setting alert thresholds, runbooks, and reliability dashboards.
Example use cases
Incident threshold for SRE runbook
“We have a 99.95% SLO and our weekly traffic window is about 800,000 requests — how many failures are we actually allowed before we breach? I need this for our incident runbook.”
Capacity planning for new service
“I'm planning a new service with a 99.9% availability target and we expect roughly 5 million requests per month. What's my error budget in terms of allowed failures?”
Alert threshold configuration
“I want to set up alerts before we burn through our error budget. Our SLO is 99.5% and we're tracking a rolling window of 250,000 requests — compute how many errors we can tolerate so I can wire up the threshold.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/error-budget-planWhen to prefer
Choose this endpoint when you need a fast, cheap, deterministic calculation to convert an SLO percentage and request volume into an allowed failure count — especially in SRE automation pipelines, alert threshold configuration, or ops math agents where you want zero upstream cost and stateless execution. Prefer over general-purpose LLM math when you need reliable, reproducible JSON output at $0.003 per call.
Side effects
- Missing slo_percent or window_requests fields returns a validation error
- slo_percent outside 0–100 range may return an error or unexpected result
- Non-numeric inputs for either field will fail schema validation
- Very large window_requests values may produce floating-point rounding in the result
