Funding Signal API

Real‑time startup funding data for sales teams, recruiters, and market analysts.

Base URL: https://parheliaweb.com

All requests must include an API key in the x-api-key header. Responses are in JSON.

💶 Pricing & Currency

All prices are listed in Euros (EUR). Your card will be charged in your local currency at the prevailing exchange rate. We use Stripe for secure payment processing, which supports 135+ currencies and local payment methods including iDEAL, Bancontact, and SEPA Direct Debit.

🔐 Authentication

Pass your secret API key as an HTTP header on every request:

x-api-key: YOUR_API_KEY

If the key is missing or invalid, you'll receive a 401 Unauthorized or 403 Forbidden.

📡 Rate Limits & Access

Your daily quota depends on your subscription tier, while the rate limit exists to prevent abuse (e.g. using the API as a DDoS bot). The two are independent: exhausting your daily quota requires waiting until the next day, whereas exceeding the rate limit only requires a short cooldown.

Plan	Daily Quota	Rate Limit	Data Access	Fields	Support
Free	100 calls / day	60 requests / minute	Last 30 days only	Basic (company, amount, round, date, url)	—
Pro (€29/month)	1,000 calls / day	60 requests / minute	Full dataset (up to 10 years)	+ sector, currency, country, lead investor, extension, investors, company_domain, hiring_signal	Email support

When the request rate exceeds the rate limit, the API returns 429 Too Many Requests. Simply retry after a short wait — this does not consume your daily quota.

🗝️ Your Key Works Across All ParheliaWeb APIs

Your API key isn't limited to this API. Use it across our full platform:

API	Endpoint Base	Free Tier	Pro Tier
Funding Rounds	/v1/funding	100/day	1,000/day
Email Validation	/v1/email/validate	100/mo	25,000/mo
Layoffs	/v1/layoffs	100/day	1,000/day
Regulatory Fines	/v1/fines	100/day	1,000/day
Acquisitions	/v1/acquisitions	100/day	1,000/day
IPOs	/v1/ipos	100/day	1,000/day

Quotas are per-API. Upgrade each API independently based on your needs. Why different quotas? Email validation performs live SMTP handshakes — per-check infrastructure cost. Data APIs query our cached database — lower marginal cost.
