aether-developer
Everything you need to connect Aether — the search engine built for agents, over SEC filings, earnings-call transcripts, and EU financial regulation — to your LLM, your IDE, or your own code.
Every result is a ready-to-cite evidence payload: the exact filed passage, an accession-numbered citation, the sec.gov / EUR-Lex link, and a confidence score. No filing, no answer — your agent stops inventing numbers.

Connect your LLM (no code)
MCP endpoint: https://api.aether.evidinvest.com/mcp · Auth: OAuth (sign in when your client prompts — free account).
| Client | How | Guide | |---|---|---| | ChatGPT | Settings → Apps & Connectors → Developer mode → Create connector with the URL above | docs/chatgpt.md | | Claude (web/Desktop) | Settings → Connectors → Add custom connector with the URL above | docs/mcp.md | | Claude Code | claude mcp add --transport http aether https://api.aether.evidinvest.com/mcp | docs/mcp.md | | Cursor |  | docs/cursor.md | | Cline / Continue / other stdio MCP | npx -y @evidinvest/aether-mcp in the client's MCP config | docs/mcp.md |
Then ask: "What does Apple's latest 10-K say about supply-chain risk? Quote the passage with the sec.gov link."
Teach your agent the craft (skills)
MCP gives the agent the tools; the skills/ directory teaches it the craft — tool routing, citation discipline, point-in-time transcript retrieval:
cp -r skills/aether-research ~/.claude/skills/ # Claude Code, personal
See skills/README.md for Claude Desktop / other frameworks.
Call the API from code
Three REST endpoints — the same tools MCP exposes (full reference):
POST /v1/tools/financial_search POST /v1/tools/transcript_search POST /v1/tools/regulation_search
TypeScript / Node
pnpm add @evidinvest/aether-sdk
import { AetherClient } from "@evidinvest/aether-sdk";
const aether = new AetherClient({ apiKey: process.env.AETHER_API_KEY });
const out = await aether.financialSearch({ query: "Apple supply-chain risk", limit: 5 });
for (const c of out.results) console.log(c.citation, c.metadata?.source_url);
Python
pip install evidinvest-aether-sdk
from aether import AetherClient
with AetherClient(api_key="ak_...") as aether:
out = aether.financial_search(query="Apple supply-chain risk", limit=5)
for c in out.results:
print(c.citation, c.metadata.get("source_url"))
curl / any language
curl -sS https://api.aether.evidinvest.com/v1/tools/financial_search \
-H "authorization: Bearer $AETHER_API_KEY" \
-H "content-type: application/json" \
-d '{"query":"supply chain risk Taiwan","limit":5}' | jq .

What's in the corpus
- SEC filings — 10-K / 10-Q / 8-K, registration statements,
prospectuses, press exhibits; ~10 years of S&P 500 and beyond.
- Non-US registries — Sweden (Bolagsverket), Japan (EDINET),
Korea (DART) annual reports; scope with jurisdiction: ["SE"|"JP"|"KR"].
- Earnings calls — speaker-attributed transcripts + furnished press
exhibits, with point-in-time filters (order: "earliest" finds first mentions).
- EU regulation — MiFID II, MiCA, DORA, the AML package; article-level
citations.
3 months free. Verify your email when you sign up and you're on the trial tier automatically — up to 5,000 API calls/hour on Aether's search tools, free for 3 months. No card required; it reverts to the free tier (100 calls/hour + paid credits) when the trial ends.
Contribute a client library
The TypeScript and Python clients are intentionally tiny — one bearer-token fetch wrapper + typed shapes for the three /v1/tools/* endpoints. Porting to Go, Rust, Java, etc. is ~150 lines. Open a PR under clients/<lang>/.
