It's a split decision.
Choose YepAPI when one API key for SEO, scraping, social and e-commerce data, and AI models fits your stack. Its calls are metered, with $5 signup credit and no rate limits, per the vendor. Choose SociaVault for public social data across 25+ platforms, with one-time credit packs that do not expire. It lists a 50-credit free trial and a 99.9% uptime SLA. Neither is the better fit for every workload; the deciding factor is breadth versus social-data focus.

02Pricing at real usage
YepAPI gives new users $5 in signup credit, with no card required. After that, calls are billed by usage: the pricing page lists Google SERP from $0.01 per call, and the homepage lists scraping at $0.01 per call. Other endpoints have their own prices; failed calls are not charged, and there are no subscriptions or monthly minimums. The vendor says there are no rate limits.
SociaVault offers 50 free credits, then sells one-time packs. The Starter Pack begins at $29 for 6,000 credits. Growth includes 20,000 credits at 18% less per credit than Starter; Pro has 75,000 at 45% less; Enterprise has 200,000 at 58% less. Credits do not expire. The per-request credit cost depends on the endpoint, so estimate your volume against the credit balance before buying.
03API, SDKs and integration
YepAPI exposes endpoints for SEO, SERP data, scraping, social and e-commerce data, and AI models. Calls use one API key and return JSON. The homepage shows POST examples, including /v1/seo/keywords/overview, /v1/serp/google and /v1/scrape. Its docs include an llms.txt file for AI agents; the homepage also names Claude Code, Cursor, Codex, an MCP server and agent skills. The vendor does not name language-specific SDKs, so plan around the HTTP API unless its docs confirm an SDK for your stack.
SociaVault provides a REST API for public data across 25+ platforms. Its homepage shows a curl request to a TikTok profile endpoint and links to API documentation. It says responses are pulled live. The vendor does not list language-specific SDKs or external software integrations. Both APIs can feed your own application or data pipeline; verify endpoint coverage and response fields against your target use case before building around them.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source license or a self-hosting option. Their documented interfaces are hosted APIs, so deployments depend on each service being available and on credentials, pricing, and endpoint behavior remaining suitable for your workload.
YepAPI returns JSON across its endpoints, while SociaVault's REST API returns structured data and reports credits used. Keep any data your application needs in storage you control, and isolate vendor-specific request and response handling behind an internal adapter. That reduces the work of changing providers, but does not automatically migrate historical data or replace platform-specific fields. Before production use, ask both vendors about data retention, deletion, export options, and terms for storing or redistributing results. Also check that each endpoint's coverage and permitted use match your application.
Questions people ask
Which API is more popular?
The vendors do not publish comparable usage figures. YepAPI's homepage reports 2.3 million API calls served and 4,900 developers signed up, but SociaVault does not provide matching figures in its homepage claims. Those metrics cannot establish which service is more popular among developers.
Which social media API is free?
Both offer a free starting balance, not an ongoing free plan: YepAPI provides $5 in signup credit, while SociaVault provides 50 credits. The credit amounts use different billing units, so compare the specific endpoints and credit costs you expect to call before estimating how long either balance will last.
Can SociaVault access private social media data?
No. SociaVault says its API covers public data only and does not bypass logins or access private data. If an application depends on private or authenticated account data, this service does not fit that requirement. Check the platform-specific endpoint documentation for the public fields it returns.
Can I self-host either API?
Neither vendor publishes a self-hosting option. The documented products are APIs accessed over the web, so build as though requests depend on the vendors' services. If self-hosting, an open-source license, or full control of the scraping infrastructure is a requirement, ask the vendors directly before committing.
