Turn event fields into a valid RFC 5545 .ics calendar file — handles timed and all-day events, escaping, line folding, and a deterministic UID for idempotent re-import — so agents can publish events that import cleanly into Google, Apple, and Outlook calendars. Add ?download=1 (or Accept: text/calendar) to receive the raw .ics file with a Content-Disposition attachment header instead of the JSON envelope. Pure compute, no LLM.

Validate data against a supplied schema — checks required fields, nested objects, arrays, enums, string formats, numeric ranges, lengths, and additional-property rules deterministically, with optional type coercion and repair, returning precise errors with JSON paths so agents can verify structured data before acting on it.

Generate agent-ready image assets (icons, logos, social graphics, thumbnails, banners) with gpt-image-1. Claude refines the prompt, screens content, adds alt text and a score. Returns image_url as a base64 PNG data URI. Flat $0.25; n=1; ratios 1:1/16:9/9:16.

Translate structured content — JSON, HTML, Markdown, templates, UI strings — without breaking structure. Preserves keys, tags, markdown, URLs, emails, variables, placeholders, code blocks, and brand names, honors a caller glossary, and validates that no placeholder was dropped, so agents can localize app content safely.

Structured live crypto market data for ~50 top assets in one JSON call: spot price and 24h open/high/low/volume/change (Coinbase Exchange) plus market cap, rank and circulating/total/max supply (CoinGecko). Quote in USD, EUR or GBP; defaults symbol=BTC vs=USD, so a bare call returns Bitcoin. 60s cache, keyless upstreams — the purpose-built replacement for scraping exchange price pages.

Extract structured data from any unstructured text into your own JSON Schema — structured-data / information extraction, text-to-JSON, LLM data enrichment. You supply the schema; the LLM returns a matching object. Works for contacts, invoices, events, product specs, medical records, legal clauses, resumes — any shape. Returns the extracted object plus token usage; unfound fields are omitted or null.

Transform a source object into a target schema — matches fields by alias and structure deterministically, uses an LLM only for semantic mapping when needed, and supports mapping hints, transforms, and defaults, so agents can reshape data between systems with per-field confidence and a clear report of what mapped and what didn't.

Moderate text content using Claude Haiku — flags categories like harassment, hate, sexual content, violence, self-harm, and spam with per-category severity and an overall allow/flag/block recommendation, so agents can screen user-generated content before publishing or storing it.

Translate up to 2000 words between languages using Claude Haiku — auto-detects source, supports 30+ target languages, preserves formatting, for larger documents and articles. For short snippets use the cheaper /translate/short.
