• evaluate_accessibilityA

  Axcess — Design Accessibility EvaluationA

  Evaluates UI elements for accessibility issues that automated scanners miss. COST: $0.01 USDC via x402 on Base-compatible EVM network per call. Checks beyond what axe/Lighthouse/WAVE catch at the design stage: - Touch targets below 24×24px (WCAG 2.5.8 AA hard fail) - Touch targets below 44×44px (WCAG 2.5.5 AAA recommended) - Information conveyed by color alone without a secondary indicator (WCAG 1.4.1) - Missing focus indicators on interactive elements (WCAG 2.4.7) - Focus rings thinner than 2px (WCAG 2.4.11) - Focus ring contrast below 3:1 against adjacent background (WCAG 2.4.11) - Interactive elements below the practical usability height floor Args: - elements: Array of 1–50 UI element objects - screen_name: Optional label for the evaluation report Each element requires: element_type. Provide width_px/height_px for touch target checks. Provide uses_color_only + secondary indicator flags for 1.4.1 checks. Provide is_interactive + focus_visible + focus indicator properties for focus checks. Returns: Structured report with: - Per-element scores (0–100) and specific issues - Severity levels (critical/major/minor) with WCAG references - What automated tools miss and why - Concrete fix recommendations - Overall score and verdict (pass/needs_work/fail) - Top issues sorted by severity

• seo_auditA

  ContrastAPIA

  One-shot SEO audit of a domain's homepage with a 0-100 composite score + a `missing_signals` list of concrete fixes. Use BEFORE pitching SEO work to a prospect, when triaging a lead's marketing maturity, or as a structured pre-flight before deeper auditing tools (Lighthouse / SEMrush). 10 audit rules each worth 10 pts: title present, title length 30-60 chars (Google SERP truncation window), meta description present, meta description length 50-160, exactly one H1, canonical link, >=3 OG tags, JSON-LD present, image alt-text coverage (proportional), HTTPS. Strictly homepage-only — we do NOT crawl the site. Ethical floor: target's robots.txt is honoured — `Disallow: /` for ContrastAPI OR `*` returns 403 `error.code = robots_txt_disallow` and we DO NOT fetch. `Cache-Control: no-store`/`private` skips our cache write (`cache_respected=false` in the response). Per-target eTLD+1 throttle (60 req/min) prevents weaponising via subdomain rotation. All target-derived strings/lists are `_untrusted`. Free: 30/hr, Pro: 500/hr. Returns {domain, fetched_url, status_code, title_untrusted, meta_description_untrusted, canonical_url, h1_untrusted, h1_count, h2_count, h3_count, images_total, images_missing_alt, internal_link_count, external_link_count, og_tags, json_ld_present, score, missing_signals, cache_respected, summary}. Returns 502 on DNS/TCP/TLS failure; 403 `robots_txt_disallow` when the target opted out.

• evaluate_typographyA

  Axcess — Design Accessibility EvaluationA

  Evaluates typography elements against a principled accessibility rubric. COST: $0.05 USDC via x402 on Base-compatible EVM network per call. Goes beyond what axe/Lighthouse/WAVE can check — evaluates design judgment, not just numeric compliance. Catches issues like: - Contrast that passes WCAG 4.5:1 but fails visually due to thin font weight - Body text that meets minimum size requirements but is still too small for comfortable reading - Line heights that technically comply but impede readability for dyslexic users - Extended all-caps or italic text that passes all AA criteria but impairs reading - Text on gradient/image backgrounds where scanner sampling is unreliable - Heading sizes that are technically correct but visually indistinct from body Args: - elements: Array of 1–50 typography element objects with font/color properties - screen_name: Optional label for the evaluation report Each element requires: element_type, font_size, font_weight, line_height, color_hex, background_color_hex. Returns: Structured report with: - Per-element scores (0–100) - Specific issues with severity (critical/major/minor) - WCAG references and what automated tools miss - Concrete fix recommendations - Overall score and verdict (pass/needs_work/fail) - Top issues sorted by severity Example use: Extract text layer properties from Figma using get_design_context, pass the typography properties to this tool for evaluation before shipping.
