At a glance
Exa gives you a proprietary semantic index with latency tiers down to ~250 ms, LLM-ready highlights, and monitoring tools. Search1API gives you results from 17 real search engines — including six Chinese engines Exa does not offer — plus a complete crawl stack, starting at $5 for 5,000 searches versus roughly $7 per 1,000 on Exa. Choose Exa if you need sub-second semantic retrieval or schema-guided summaries; choose Search1API if you want true SERP coverage, Chinese web access, and more searches per dollar.
| Search1API | Exa | |
|---|---|---|
| Search source | 17 real engines incl. Reddit, X, YouTube | One proprietary neural index |
| Entry cost / 1,000 | $1.00 ($5 = 5,000 searches) | ~$7.00 PAYG + monthly platform fee |
| Searches at ~$99/month | 150,000 (Pro) | ~14,000 (≈$700 at PAYG) |
| Chinese engines | 6: WeChat, Bilibili… | None |
| Site-level crawler | /deepcrawl + free status polling | None — single-page livecrawl only |
| Credit expiry | Never expire | Not documented |
| Exact dates & geo filters | Time-range buckets only | Exact dates + country targeting |
Search1API vs Exa, category by category
Tables hide trade-offs, so here is what each difference actually means in practice.
How results are produced
We aggregate live SERPs from 17 real engines, so what an agent sees is what a human would see searching Google, Bing, Reddit, or Baidu directly. Chinese platforms — WeChat articles, Bilibili videos, Sogou and 360 web results, Quark — are first-class engines with dedicated endpoints.
Exa embeds and indexes the web itself into a neural index. That enables semantic retrieval (“find pages like this”) and very fast instant answers, but coverage depends on their crawl, not on any public engine.
If your agent needs ground-truth SERP data or the Chinese web, Search1API covers it natively. If you need similarity-style retrieval over English content, Exa’s index is purpose-built for that.
Content fetching
A complete crawl stack: /crawl returns cleaned page content, /deepcrawl walks entire sites with status polling, /sitemap enumerates URLs, /screenshot renders pages (12 parameters including full-page, viewport, and dark mode), and /extract turns a URL into schema-shaped data.
There is no site-level crawler. /contents fetches single pages via livecrawl with subpages, highlights, summaries, and cache control — strong per-page tooling, but it will not traverse a domain.
Both return clean text; only Search1API can enumerate and pull whole sites, and Exa bills each content type separately while our crawl endpoints cost a flat credit.
Agent integration
Hosted MCP server over Streamable HTTP with OAuth 2.1 (PKCE + dynamic client registration) instead of pasting keys into URLs, the s1 CLI with OAuth login, official Agent Skills, and TypeScript/Python SDKs. Searches support array batching — failed items are not billed.
A hosted MCP server, SDKs, and streaming SSE output. Their MCP story is solid; this category is roughly parity.
Pick either for transport. The differentiator is what sits behind the endpoint — 17 engines plus crawlers versus one index.
Where Exa is genuinely ahead
We say this plainly because evaluators will check: Exa supports exact published-date ranges and country targeting (we offer time-range buckets only), result synthesis and highlights that cut downstream tokens, change-tracking Monitors, Websets, people/company/code/news vertical indexes, and latency tiers down to ~250 ms.
These are real capabilities we do not currently match.
If your workload leans on any of those, stay with Exa — or use both, since many teams pair a semantic index with real-SERP verification.
Pricing compared at the same tier
Vendors return different payloads per request (Exa returns LLM-ready chunks and summaries we do not synthesize). What can be compared apples-to-apples is price per request volume:
| Search1API | Exa | |
|---|---|---|
| Free tier | 100 credits, no card required, never expire | $20 sign-up credit, then a ~$10/month platform fee |
| Cheapest paid step | $5 top-up → 5,000 searches ($1.00 per 1,000) | Pay-as-you-go from ~$5 → ~714 searches (~$7.00 per 1,000) |
| $99/month tier | 150,000 searches ($0.66 per 1,000) | ~14,000 searches at PAYG rates (~$700 spent) |
| ~100,000 searches/month | ≈ $66–99/month depending on plan mix | ≈ $700/month at PAYG rates |
| Credit expiry | Never | Not documented |
Figures use each vendor’s published rates as of August 26, 2026. Exa prices contents by content type, so multi-format reads cost more than the base rate shown here.
Who should choose which
Choose Exa if you need
Semantic “find-me-similar” retrieval with published latency as low as ~250 ms
Exact date-range filtering and country targeting inside the search call
Highlights, summaries, and schema-guided outputs to minimize tokens fed to your LLM
Monitors, Websets, and vertical indexes for people, companies, code, and news
Choose Search1API if you need
Real SERP results from 17 engines — what users actually see on Google, Bing, Reddit, X, and more
Chinese web access: WeChat, Bilibili, Baidu, Sogou, 360, Quark (no AI-search vendor else covers these)
Crawl, deep crawl, sitemap, screenshots, and extraction bundled at flat credit pricing
Predictable spend: credits from $5, never expiring, with auto-recharge and bonus tiers
Switching from Exa to Search1API
The mental model shifts from one semantic index to engine selection. Most calls map 1:1:
| Exa | Search1API | |
|---|---|---|
| POST api.exa.ai/search | query, numResults map directly; type/category/userLocation have no direct equivalent — pick the closest engine | POST api.search1api.com/search with query, search_service, max_results (≤50) |
| /contents (text of a URL) | Clean markdown/text out both ways | POST /crawl with the same url |
| /contents (summary / structured) | Schema-guided summaries map to extract | POST /extract with prompt and response_format |
| includeDomains / excludeDomains | Direct equivalents | include_sites / exclude_sites |
| Monitors, Websets, deep-reasoning | Genuinely unmatched by us right now | No equivalent today — keep Exa for these if you rely on them |
Frequently asked questions
What is the best alternative to Exa?
It depends on why you are leaving. If your complaint is cost per search or index coverage, Search1API replaces Exa’s role as your agent’s web layer: real SERP results from 17 engines, crawling included, entry price around $1 per 1,000 searches versus roughly $7 on Exa. If you depend on sub-second semantic retrieval or Monitors/Websets, Exa remains the stronger fit for those specific features.
Is Search1API cheaper than Exa?
At entry tier, about seven times cheaper per 1,000 searches ($1.00 vs ~$7.00). At the ~$99/month tier, the Pro plan delivers 150,000 searches while the same budget buys roughly 14,000 Exa searches at published pay-as-you-go rates. Note the two APIs return different payloads — Exa synthesizes LLM-ready chunks; we return SERP results plus optional raw page content — so treat this as a price comparison, not an output-equivalence claim.
Does Search1API have a semantic index like Exa?
No. We aggregate live results from real search engines instead of maintaining our own index. You gain verifiable SERP coverage (including six Chinese engines) and lose similarity-based retrieval — if “find pages conceptually like this” is your core need, a neural index is still the better tool.
Can I run both during migration?
Yes, and most teams do for a few weeks. Start with 100 free credits (no card), mirror your highest-traffic Exa queries through /search and /crawl, compare outputs, then flip traffic endpoint by endpoint. Purchased credits never expire, so unused balance carries no risk.
Do Search1API credits expire like platform fees?
No. Exa pairs pay-as-you-go with a recurring platform fee; we have no platform fee and purchased credits never expire. Subscriptions start at $19/month if you prefer fixed monthly pricing.
