HubVibe: 38 Machine-Payable Dev Utilities and WCAG Audits

Full website audit in one call: accessibility (WCAG 2.1 A/AA via axe-core), on-page SEO, HTTP security headers and page speed / page weight, from a single browser load of one URL. Cheaper than four separate calls; if any part cannot run, nothing is billed. $0.15 per call. Returns: pass (bool) plus wcag{}, seo{}, security{}, performance{} sub-results.

Page speed and page weight audit of a web page from one real browser load: total bytes transferred, HTTP request count and DOM node count, measured rather than estimated, with findings when the page is heavy. Page-weight signals, not Core Web Vitals. $0.05 per call. Returns: pass (bool), metrics{}, findings[] with id/severity/detail.

Security headers check for a website: audits HTTPS, HSTS, Content- Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options / clickjacking protection, Referrer-Policy and CORS from the real HTTP response of any live URL. Findings with severity for what is missing. Header posture only, not a penetration test. $0.05 per call. Returns: pass (bool), findings[] with id/severity/detail.

SEO audit of a web page (on-page SEO check) for any live URL or raw HTML: title tag, meta description, H1 heading structure, canonical link, OpenGraph and social tags, JSON-LD structured data, html lang attribute. Rule-by-rule findings with severity and what is missing or malformed. $0.05 per call. Returns: pass (bool), findings[] with id/severity/detail.

Website accessibility audit (a11y, WCAG compliance check): WCAG 2.1 level A and AA conformance of any live URL or raw HTML, tested with axe-core in a real headless browser. Returns every violation with rule id, impact, help text and affected node count. Deterministic rules; a check that cannot run returns an error, never a pass. $0.05 per call. Returns: pass (bool), violations[] with id/impact/help/help_url/nodes_affected.

Everything about one Base mainnet address in a single call: ETH balance, transaction count, and whether it is a contract or an externally owned account. Three chain reads folded into one answer. $0.05 per call. Returns: balance_wei, balance_eth, transaction_count, is_contract, code_size_bytes.

Current Base mainnet block height and gas price, read live from a Base RPC node. Use to check chain liveness or time an on-chain action. $0.02 per call. Returns: block_number, gas_price_wei, gas_price_gwei.

A generic allowlisted read-only JSON-RPC call to Base mainnet: your method, your params. A JSON-RPC error (a revert reason, 'block not found') comes back as the result, not a failure -- it is the chain's own answer to exactly this call. $0.05 per call. Returns: method, result or error, endpoint.

One Base mainnet transaction with its receipt folded in: sender, recipient, value, block, success or failure, and gas actually used. $0.05 per call. Returns: from, to, value_eth, block_number, status, gas_used, log_count.

Run Python code in Google's own hosted sandbox and get the executed code, its output, and the outcome back. Not run in this service's own infrastructure. $0.25 per call. Returns: code, output, outcome, summary, model.

Detect anomalies in a target table's time series against a history table, using AI.DETECT_ANOMALIES (TimesFM). Both tables share the same timestamp and value column names. $10.00 per call. Returns: history_table, target_table, timestamp_col, data_col, anomaly_prob_threshold, columns[], rows[], row_count, gib_processed.

Forecast a time series in a BigQuery table with Google's pretrained TimesFM model (AI.FORECAST) -- no model to train. Point it at the table and the timestamp/value columns. $10.00 per call. Returns: table, timestamp_col, data_col, horizon, columns[], rows[], row_count, gib_processed.

Execute a read-only BigQuery SQL query, including against Google's public datasets, and get the rows back as JSON. Every query is dry-run first and refused if it would scan more than the byte ceiling, so cost is bounded before anything runs. $0.50 per call. Returns: columns[], rows[], row_count, gib_processed, cache_hit.

Ask a question in plain language about any BigQuery table, including Google's public datasets, and get a written answer with the SQL and the rows it came from. Writes the query, runs it under a byte ceiling, and reads the result back as an analysis. $5.00 per call. Returns: answer, sql, columns[], rows[], gib_processed.

Fetch any web page and return its readable text, title, description and links, rendered in a real browser so JavaScript-built pages extract correctly. Falls back to direct fetch when rendering is unavailable. $0.10 per call. Returns: title, description, text, text_chars, links[], javascript_rendered.

Fetch any URL and get back exactly what the server sent: status code, headers, and body. Unlike extract.page, every status code is a result, not a failure -- a 404 or 500 from the target is delivered as one. $0.10 per call. Returns: url, final_url, status, content_type, bytes, text, truncated, headers{}.

Generate one image from a text prompt using Imagen 4. Returns the image as base64-encoded bytes. $0.50 per call. Returns: prompt, aspect_ratio, image_base64, mime_type, model.

Answer a specific question about text you supply, using Gemini. Answers only from the material given and says so explicitly when the material does not contain the answer, rather than guessing. $0.25 per call. Returns: answer, model, tokens{prompt,output}.

Pull named fields out of text and return them as a JSON object with exactly the keys you asked for. Fields the text does not state come back as null instead of being invented. $0.25 per call. Returns: fields{} with one key per requested field.

A raw completion from a large language model: your prompt, your system message, your provider and model choice among what this deployment has configured (Gemini; Claude on Vertex once Model Garden access is enabled). Unlike llm.analyze, nothing is prescribed about the shape of the answer. $0.25 per call. Returns: text, model, provider, finish_reason, usage{input_tokens,output_tokens}.

Search for places -- businesses, addresses, points of interest -- via Google's managed Maps Grounding Lite MCP server. Requires the operator to enable the Maps Grounding Lite API and set a key; unavailable until then. $0.10 per call. Returns: query, result (places found, per Maps Grounding Lite's own shape).

Directions and travel time between two places, via Google's managed Maps Grounding Lite MCP server. $0.10 per call. Returns: origin, destination, travel_mode, result (route, per Maps Grounding Lite's own shape).

Current or forecast weather at a named place, via Google's managed Maps Grounding Lite MCP server. $0.10 per call. Returns: location, result (weather, per Maps Grounding Lite's own shape).

Combine a live crypto spot quote with live prediction-market probabilities on the same subject and get them analysed together in one call. Market data and implied probabilities only -- not investment advice. $5.00 per call. Returns: spot{}, prediction_markets[], analysis, disclaimer.

Live prediction markets and the probabilities they currently imply, from Polymarket. Search by topic or take the highest-volume markets. Returns each outcome as a percentage, not a raw price. $0.05 per call. Returns: markets[] with question, implied_probabilities[], volume, end_date.

Live spot price and 24-hour change for any Coinbase product (BTC-USD, ETH-USD and the rest), from Coinbase's public market data. $0.02 per call. Returns: price, price_change_24h_pct, volume_24h, base/quote currency.

Coinbase's exchange-rate table for one base currency against every currency it quotes -- crypto and fiat. $0.02 per call. Returns: currency, rates{}.

Live bid, ask and volume for one Coinbase product, from an independent market-data host to market.quote -- a genuine second source, not the same read twice. $0.02 per call. Returns: product_id, price, bid, ask, volume, time.

Re-fetch a page monitor.snapshot was called on, and get back whether it changed and a summary of what changed. $0.50 per call. Returns: url, title, changed, baseline_age_seconds, change_summary, model.

Fetch a page and save it as the baseline for monitor.check. Call this once, then monitor.check later to see what changed. $0.50 per call. Returns: url, title, text_chars, content_hash, note.

Live Polymarket events -- groupings of related markets -- ranked by volume. $0.05 per call. Returns: events[{id,title,slug,volume,end_date,market_count}], count.

One named Polymarket market, looked up by its exact slug, with its current implied probabilities. $0.05 per call. Returns: slug, market{question,implied_probabilities[],...}.

Deterministic statistics over (x, y) points: ordinary least squares linear regression with standard errors and confidence intervals, a fitted normal distribution with quantiles and probability queries, exact Student t and Jarque-Bera p-values validated at your alpha, and predictions with prediction intervals. Points come inline or from a BigQuery table (two numeric columns; above max_rows the rows are chosen by fingerprint, never at random). Pure arithmetic with exactly rounded sums: the same input always returns the same numbers, and no LLM is anywhere in the path. $0.50 per call. Returns: source{}, n, alpha, confidence_level, metrics[], linear_regression{}, normal_distribution{}, p_values{}, prediction[], notes[], method.

Read any web page and get a written answer to your question about it. Renders the page in a real browser, extracts the content, and analyses it in one paid call. Answers only from the page, and says when the page does not contain the answer. $5.00 per call. Returns: brief, title, final_url, source{}, model.

A research brief on a company from live web sources: what it does, its products, and anything notable, cited to [n] source numbers, with thin or conflicting evidence disclosed rather than papered over. $10.00 per call. Returns: company, report, sources[{n,url,title}], partial[], model.

Read any web page and return exactly the fields you name as JSON -- pricing, contact, product names, whatever you ask for. Fields the page does not state come back null rather than invented. Built for pipelines that need a fixed shape. $5.00 per call. Returns: fields{} with one key per requested field, plus title and final_url.

Answer a question from a live web search: search, read the top sources, and get a cited answer with every claim tied to [n] source numbers. $5.00 per call. Returns: question, answer, sources[{n,url,title}], partial[], model.

A live web search, answered from current Google Search results with the sources it used. Grounded, not the model's own memory. $0.10 per call. Returns: query, answer, sources[{url,title}], search_queries_used[], model.

Probe a customer-specified MCP server's initialize handshake and tools/list: whether it requires authentication, what protocol version it speaks, and which of its tools are not marked read-only. $5.00 per call. Returns: reachable, requires_auth, protocol_version, tool_count, tools[], tools_without_readonly_annotation[].

Convert text to spoken audio (MP3) using Google Cloud Text-to-Speech. $0.25 per call. Returns: text_chars, voice, audio_base64, mime_type.

Transcribe up to 60 seconds / 10MB of audio using Google Cloud Speech-to-Text. Longer audio is refused before payment; this is the synchronous API only. $0.25 per call. Returns: transcript, language_code, confidence, model.

Check up to 10 specific claims against up to 4 specific source URLs. Each claim comes back SUPPORTED, CONTRADICTED or UNSUPPORTED, with the quote the verdict is based on. $5.00 per call. Returns: claims[], verdicts[{claim,verdict,quote,source_n}], sources_read[], sources_unread[], model.
