Frequently asked questions

No. The Basic tier is free on every API — 100 requests/month with no card required. Subscribe via RapidAPI and use your key immediately.

Almost. Your single RapidAPI account works across every Helix-API listing, but each API has its own subscription tier. Subscribe to each one you need (the free Basic tier is one click). The X-RapidAPI-Key stays the same; only the X-RapidAPI-Host header changes per API.

Sign up at rapidapi.com and visit any Helix-API listing. Your key appears in the right sidebar after subscribing.

Four tiers per API: Basic (free, 100/mo), Pro ($9.99/mo, 10K), Ultra ($29.99/mo, 100K), Mega ($99.99/mo, unlimited). All billing is handled by RapidAPI and appears as one consolidated invoice.

Requests beyond your plan return HTTP 429 until the next billing cycle. You can upgrade mid-cycle and the new quota applies immediately.

Yes. Cancellation takes effect at the end of your current billing period. No questions asked.

99.9% monthly uptime on Pro+ plans. Service credits apply if we miss the SLA. See Terms for credit calculation.

Production servers run on Railway in US-West (AWS Oregon). Median latency from North America is under 100ms. Multi-region rollout is on the roadmap for Q1 2027.

Scraping-based APIs depend on third-party sources; if Google blocks all scrapers globally, our SERP API will return errors until they unblock. We exclude these third-party outages from SLA calculations but always disclose them on the status page.

We log metadata (timestamp, endpoint, status, latency, approximate region) for 30 days to bill correctly and detect abuse. We do NOT log request bodies (prompts, URLs, images) or response bodies. See our Privacy Policy for details.

Yes. You can access, export, or delete your data via privacy@helix-api.com. We respond within 30 days.

Email security@helix-api.com. We follow responsible disclosure practices and acknowledge reports within 48 hours.

Every endpoint returns JSON with the shape: { status, data, meta, timestamp }. The meta object includes cached, latency_ms, and request_id for tracing.

Yes — the Webhook Relay API lets you create endpoints for async results, and several long-running APIs (image generation, OCR on large files) support webhook delivery.

Native SDKs for Python, Node.js, Go, Ruby, and PHP are on the roadmap for Q4 2026. In the meantime, our OpenAPI 3.0 specs let you auto-generate SDKs in any language with openapi-generator.

Yes. Every API serves its spec at /openapi.json. The 3.0.3 version is also imported into each RapidAPI listing.
