If your agent already talks to Exa, you do not need a new client to try our search. Exa's own SDKs take a base URL, and our /v1 endpoints answer in Exa's request and response shape: search, getContents, findSimilar, answer (with streaming and structured outputSchema answers).
Python
from exa_py import Exa exa = Exa(api_key="YOUR_KEY", base_url="https://tools.funwords.eu/v1") # EU law, answered from our article-by-article index r = exa.search("NIS2 incident reporting deadline", category="law", num_results=5) # Companies, answered from official business registers r = exa.search("Spotify AB", category="company", num_results=5) JavaScript
import Exa from "exa-js"; const exa = new Exa(process.env.API_KEY, "https://tools.funwords.eu/v1"); const res = await exa.search("KONE Oyj", { category: "company", numResults: 5 }); The SDKs send your key in the x-api-key header, which we accept as they send it.
Where each request goes
| What you send | Where the answer comes from |
|---|---|
category: "law", or includeDomains: ["eur-lex.europa.eu"] | Our EU law index: 47 acts (GDPR, AI Act, DSA, DMA, NIS2, DORA, MiCA, VAT, PSD2, AML…) split into articles, hosted in the EU |
category: "company" with a company name | Official registers of France, Sweden, Norway, Finland, Czechia and Estonia, plus GLEIF; results carry register IDs and LEIs |
category: "research paper" | OpenAlex and Crossref (or arXiv) |
category: "github" | GitHub's own search |
getContents | The live page, fetched when you ask; PDFs included |
answer | Cited answers; EU-law questions are answered from the law index |
Why switch, and why not
We measured instead of guessing. On 102 EU compliance questions written before either search ran, our law index put the right article first 76 times, Exa's web search 34. For companies both found 10 of 10, but only ours returned the register ID. On research papers Exa was slightly ahead (17 vs 16 of 20). Questions, scoring and scripts are public on our benchmarks page.
Where Exa is clearly better: the open web. Its own index is far larger than anything we run, and we do not search people. If most of your queries are general web research, stay with Exa for those and send the European records questions to us; it is one base URL per client.
Things Exa does not have
The same key also opens endpoints outside the SDK:
# Sanctions screening against the EU, UN, UK and US (OFAC) lists curl -H "Authorization: Bearer $API_KEY" "https://tools.funwords.eu/sanctions/check?name=Vladimir%20Putin&lists=eu,un,uk,ofac" # Know-your-business check for a European company in one call curl -H "Authorization: Bearer $API_KEY" "https://tools.funwords.eu/pack/kyb-eu?q=Spotify%20AB" There is also a VAT number check (VIES), e-invoice validation and document text extraction, all on the same key, and every endpoint can also be paid per call over x402 by an agent with a wallet.
Price
A free key gives 100 calls a month with no card. After that it is $0.005 to $0.01 per successful call, or $9 a month for 1,500 calls; failed calls are never charged.
If you have a European search case we get wrong, tell us in the comments. We add hard cases to the next benchmark run.
