Dev Utilities Validator — Apify Actor (pay-per-event)

Deterministic validation and normalization for JSON Lines, file checksums, and SVG accessibility structure. Wraps the exact same real, tested logic already shipped as the etsa-mcp-dev-utilities-001 MCP server (dev_utilities_core.py) — one proven capability, a second distribution manifestation, not a rewrite.

Operations (`input.operation`)

jsonl_validate — validate newline-delimited JSON text (input.text)
checksum_manifest — SHA-256 manifest for explicit file paths (input.paths)
svg_viewbox_check — structural/accessibility check of SVG markup (input.markup)

Pricing (pay-per-event, configured live in the Apify Console's Publishing > Monetization wizard)

actor-start: $0.01 — charged once the Actor validates input and starts
validation-result: $0.02 — charged once per successful result
Platform usage cost is included in the above prices, not passed through to the caller (verified on the real Review screen)

No rental, no per-compute-unit billing — matches Apify's 2026 pay-per-event migration (rental pricing being retired).

Local testing (real, done)

Tested against the real, installed apify Python SDK (v4.0.1) in an isolated venv, using APIFY_LOCAL_STORAGE_DIR for local storage and ACTOR_TEST_PAY_PER_EVENT=1 to exercise the real pay-per-event charging path locally (Actor.charge()) without a live platform account. All three operations produced correct, verified output:

jsonl_validate: correct valid/blank/invalid counts and type breakdown
svg_viewbox_check: correct PASS/FAIL and per-check breakdown
checksum_manifest: correct SHA-256 digest, independently verified

Deployed and public

Real, published, public Apify Actor: https://apify.com/engineertsaistudio/dev-utilities-validator (Actor ID 3EV4NAlqaqMV0TSfG). Built (0.0.3), test-run succeeded against a live sample (2 valid records, 1 invalid line correctly reported), and pay-per-event monetization is Active. Payout/KYC completeness for real payouts is tracked separately and not implied by publication alone.

Agentic payments

Pay-per-event Actors with limited permissions are eligible for Apify's agentic payment paths (x402 / Skyfire), meaning an AI agent — not just a human — could discover, run, and pay for this Actor once published. This is a first-class distribution rail for a deterministic, non-scraping tool like this one.
