Changelog
What is new, improved, and fixed on DevOpsil.
API Health Monitor (Live)
Launched the API Health Monitor at /api/v1/health/check. Submit up to 50 endpoint check specs in one call; checks run in parallel from DevOpsil infrastructure — no agent to deploy. Each check measures HTTP status code, response latency, TLS certificate details (expiry date, days remaining, issuer, subject, serial), DNS resolution time and resolved IP, and evaluates per-assertion results. Supported assertions: status code (exact or default 2xx), body_contains, body_not_contains, body_matches (regex), json_path (dot-notation into parsed JSON), json_value, header_exists, header_value, max_latency_ms (triggers degraded status), tls_min_days (triggers fail). Check statuses: pass, degraded (latency threshold exceeded), fail (assertion failed, timeout, or connection error). SSRF protection: requests to localhost, 127.x, 10.x, 172.16-31.x, 192.168.x, and instance metadata endpoints (169.254.169.254, metadata.google.internal) are blocked. Free tier: 50 calls/month. Includes a post-deploy verification shell script example.
Distributed Rate Limiting API (Live)
Launched the Distributed Rate Limiting API at /api/v1/ratelimit. Three endpoints: POST /increment (check and consume quota), POST /check (peek without consuming), POST /reset (admin override). Supports three algorithms: fixed_window (simple counter, lowest overhead), sliding_window (accurate rolling window via Redis sorted sets, default), and token_bucket (smooth burst handling with configurable refill rate). All keys are namespaced for multi-service isolation — e.g. 'api', 'login', 'checkout'. The identifier can be any string: user ID, IP address, API key prefix, session token. Token bucket supports configurable capacity and refill_amount per window. Responses include standard X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset headers plus Retry-After on 429. Cost parameter supports weighted operations (e.g. a bulk operation costing 10 units). Pure Redis — no LLM pass — making it sub-millisecond and suitable for high call volumes. Free tier: 1,000 calls/month. Includes Express.js middleware integration example.
Deployment Risk Score API (Live)
Launched the Deployment Risk Score API at /api/v1/deploy/risk. Submit a git diff and optional service metadata (name, environment, criticality, tech stack) and receive a 0–100 risk score, risk level (minimal/low/medium/high/critical), plain-English summary, list of risky files with severity, risk factors (17 types: DB migrations, auth changes, payment code, infra, Kubernetes, CI/CD, secrets exposed, API contracts, etc.), actionable recommendations, and a deploy window recommendation (immediate/scheduled/off_hours/hold). Two-pass analysis: heuristic pass (regex file classifiers + content pattern matching) followed by a Claude Sonnet LLM pass for context-aware scoring and natural-language output. Use heuristic_only: true to skip the LLM pass for faster, cheaper results. Max 512KB diff. Includes a GitHub Actions PR gate example.
PII Scrubbing API (Live)
Launched the PII Scrubbing API at /api/v1/pii/scrub. Two modes: redact (replaces PII with [CATEGORY] labels) and tokenize (replaces with reversible tokens like [EMAIL_1] and returns a token_map for restoration). Detects 16 structured PII types via regex: email, phone (US + international), SSN (Luhn-free), credit cards (Luhn-validated), public IPv4/IPv6, IBAN (checksum-validated), ABA routing numbers, US passport numbers, VINs, MAC addresses, Ethereum/Bitcoin addresses, URLs with embedded credentials, UK postcodes, US ZIP codes, and dates of birth. Optional Claude NLP pass for person names and physical addresses (opt-in, documented as costing 5 calls each). Includes a detokenize action to reverse tokenized output. Max 512KB per request. Detokenize endpoint included in the same route.
Secrets Leak Detection API (Live)
Launched the Secrets Leak Detection API at /api/v1/secrets/scan. Submit any text — git diffs, log files, config files, or freeform content — and receive a structured findings report with severity scores, masked value previews, line numbers, and per-finding remediation guidance. Detects 50+ named secret types across AWS, GCP, GitHub, Azure, Stripe, Slack, Twilio, SendGrid, HashiCorp Vault, Terraform Cloud, database connection strings, SSH/RSA/EC private keys, JWT secrets, npm tokens, and more. Supplemented by Shannon entropy analysis to catch unrecognised high-entropy secrets. Context modes: git_diff (only scans added lines), log, config, freeform. Free tier: 100 scans/month. Includes a CI/CD integration example for GitHub Actions PR checks.
DevOpsil API Products — Webhook Reliability API (Live)
Launched the first DevOpsil product API: Webhook Reliability API at /api/v1/webhooks. Register destination endpoints, ingest events via a single POST, and DevOpsil handles guaranteed delivery with 8-attempt exponential backoff (up to 24h), HMAC-SHA256 signed payloads, idempotency key support, event replay, and a full delivery audit log per event. Free tier available (500 calls/month) — no credit card required. Includes: endpoint management (register, update, delete, test ping), event history with delivery status, replay for any event in the last 30 days, and per-minute burst rate limiting. API keys managed from the new /dashboard/api-keys page.
API Products Landing Page & Interactive Documentation
New /api-products page showcasing all current and upcoming DevOpsil infrastructure APIs with pricing tiers, feature lists, and CTAs. New /api-docs page with interactive endpoint documentation, copy-able curl examples, signature verification code samples, rate limit tables, and error code reference.

Try It playground moved to top of docs page.
Talent Application — Country Dropdown, Work History Present, External Certifications & Draft Save
Four improvements to the Talent application form: (1) Country field is now a searchable dropdown with all 195 countries. (2) Work history entries have a "Currently working here" checkbox that shows "Present" instead of an end date. (3) Engineers can now add certifications from other organisations (CKA, AWS, GCP, etc.) with name, issuing org, issue date, a verification URL, or an uploaded certificate file (PDF/image via Cloudflare R2). (4) Application form auto-saves to localStorage so progress is preserved if the tab is closed — restores on next visit and clears on successful submit.

The user dashboard at /dashboard now shows a DevOpsil Talent section. Users without a profile see a CTA to apply.
