GigSoul API for developers

30 AI business tools for marketing, sales, content, SEO, and workflow automation, behind one standard API key. Monthly plan, billed by card via Stripe, with a monthly bucket of included calls - built for people, teams, and platforms that expect conventional billing (marketplace plugins, procurement, expense cards).

Starter$9 / month1,000$0.009

Scale$99 / month25,000$0.004

Every tool call counts as one included call, regardless of tool. When you hit the monthly cap the API returns 429 with an upgrade link - no surprise overage charges. Usage resets at each renewal.

Get a key in two minutes

1. Start a subscription (replace the tier with starter, growth, or scale):

curl -X POST https://pro.gigsoul.com/v1/signup/start \
  -H "Content-Type: application/json" \
  -d '{"email":"[email protected]","tier":"starter"}'

2. Open the returned checkout_url and pay by card. Stripe sends you back to the claim page, which shows your gsk_live_... key exactly once. Store it somewhere safe.

  -d '{"context":"paste the email copy here"}'
