the $0.0020 numbers only hold if you use the whole plan, so the real cost at your volume is higher. firecrawl standard comes to $99 for 18000 credits and scraperAPI hobby to $49 for 37000, which is the fairer comparison
bright data's $13.50 depends on how 403s, 404s and captcha pages get billed, and the pricing page doesn't say, so it's worth checking before you rely on it.
for extraction, json mode adds about $7.92 at the standard rate, so it only comes out ahead if your own LLM spend on those pages is higher than that
