Free tier, no form to fill in. Signing in shares your email address with us — we store it to create your key and to recognise you if you sign in with another provider. See our Privacy Policy and Terms.

OpenAPI Specification
openapi: 3.2.0
info:
title: LaminarForge Platform API
description: 'Format conversion and text processing utilities powered by Cloudflare Workers. Provides JSON/CSV/XML/YAML converters, case/slug/base64 utilities, date/color/roman converters, text analysis, UUID generation, password/name/lorem generators, and more.
Four worker deployments serve these endpoints:
- **lf-format-utils** — Format conversion & formatting endpoints
- **lf-text-utils** — Text analysis & generation endpoints
Shared platform endpoints (health, keys, usage, billing) are available on all workers.
- **lf-web-intel** — Web intelligence & OSINT (WHOIS, DNS, SSL, geoip, HTTP headers, redirects)
- **lf-business-utils** — Business data (country info, timezone, calendar, sales tax, VAT, loan, holiday, currency)
PAY PER CALL (x402): no account needed. Call any endpoint without credentials and it returns HTTP 402 with a JSON body listing the price, network, USDC asset and payTo address. Pay, retry with the X-PAYMENT header, and the call goes through. GET /v1/prices on any service lists every endpoint''s price. Standard calls are $0.002. Heavy ones (PDF, images, screenshots, scraping) are $0.01. Two schemes are offered: ''exact'' (one transfer per call, zero setup) and ''batch-settlement'' (open a channel once, then many calls settle in far fewer transfers — cheaper for volume).'

summary: Create API key
description: 'Generate a free-tier API key. Returns the raw key once — save it immediately; it is stored as a SHA-256 hash and the raw value is never retrievable again.
