02Pricing at real usage
YepAPI has no subscription or monthly minimum. New accounts receive $5 in signup credit. The pricing page lists Google SERP calls at $0.01, keyword overview from $0.03, and web scraping at $0.01; other endpoints and models have their own metered prices. Usage is prepaid, and failed calls are not charged. The page says there are no rate limits.
SerpWow sells monthly credit allowances on annual billing: Starter is $125/month for 10,000 credits; BigData is $399 for 50,000; Volume is $960 for 250,000; Infrastructure is $2,399 for 1 million; and Infrastructure XL is $7,200 for 5 million. Listed prices are billed annually, with a 20% annual discount; monthly prices are not published. Extra credits cost from $0.024 on Starter down to $0.0036 on Infrastructure XL. The product page invites users to try SerpWow free but does not state the allowance. Compare projected credit use with per-call costs before choosing.
03API, SDKs and integration
YepAPI is an HTTP API. Calls use one API key and return JSON across SEO, scraping, social and e-commerce, and AI model endpoints. The homepage shows POST requests such as /v1/seo/keywords/overview and /v1/serp/google. Its docs include llms.txt, and the homepage lists an MCP server and agent skills, with named integrations for Claude Code, Cursor, and Codex. These options target direct API use and coding-agent workflows. The vendor does not name language-specific SDKs in its integration list.
SerpWow is a SERP API with API pull, webhook push, and delivery to S3, GCS, or Azure. Responses can be JSON, CSV, or HTML. Its product page lists Google search, AI Overviews, news, trends, images, videos, reverse image search, Maps, and Shopping, along with batch searches. It offers a product tour and API access, but does not name language-specific SDKs or a CLI. Choose based on integration surface: YepAPI covers agent-assisted multi-endpoint work; SerpWow supports search pipelines and multiple delivery formats.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source licence or self-hosting option; both are offered as hosted APIs. YepAPI's single key and JSON response pattern can simplify client setup across endpoints, but moving away still means replacing its API paths and mapping endpoint-specific fields. SerpWow supports JSON, CSV, or HTML output and delivery to S3, GCS, or Azure. Those options give teams choices for downstream storage, not a stated portability guarantee.
Plan migration around queries, response fields, and billing units: YepAPI meters endpoint and model usage, while SerpWow uses credits and plan-specific extra-credit rates. Ask each vendor about retention, bulk export, and contract terms before relying on stored results.
Questions people ask
Is YepAPI cheaper than SerpWow?
It depends on usage and endpoint mix. YepAPI lists Google SERP calls at $0.01 and has no monthly minimum, while SerpWow starts at $125/month billed annually for 10,000 credits. SerpWow's per-credit cost falls on larger plans, but the vendor does not state how many credits each specific query consumes.
Does either service have a free tier?
YepAPI offers $5 in signup credit and says no card is required; it does not have a free plan. SerpWow's product page says “Try for free,” but its pricing information does not state the trial allowance. Confirm the free-use limit before estimating a test or development budget.
Can SerpWow replace YepAPI for scraping or AI models?
SerpWow's listed scope is search-engine results and related verticals, including Maps and Shopping. YepAPI also lists web scraping, social and e-commerce data, and 285 AI models. If your application calls those non-SERP endpoints, SerpWow's published feature set does not describe an equivalent.
Can I run either API in my own infrastructure?
Both are presented as hosted APIs, and neither vendor publishes a self-hosting option or open-source licence. SerpWow can deliver data to S3, GCS, or Azure, which supports downstream storage but is not the same as running its service locally. Ask the vendor about deployment and data-retention requirements.
