Phase 1 · Data & Finance APIs · Private Beta

The discovery
layer
for AI agents.

Indexa is the standard interface through which AI agents find and select services. Structured listings. Machine-readable specs. No prose, no sales calls, no friction.

Starting with a curated catalog of data & finance APIs. Free to query during adoption phase.

How it works

Search. Compare. Integrate.

Three programmatic steps. No human in the loop.

SEARCHSTEP 01

Query the catalog

Send a structured query — category, capability, input/output format, SLA. Get back ranked service listings as typed JSON.

example

"color:#b8ff57">indexa.search({
  category: "financial_data",
  capability: "get_stock_price",
  output_format: "json_schema"
})
COMPARESTEP 02

Evaluate specs

Every listing exposes identical fields: inputs, outputs, pricing model, reliability SLA, auth method. No prose. No ambiguity.

example

"color:#b8ff57">listing.reliability.uptime_sla_pct  // 99.9
"color:#b8ff57">listing.pricing.model               // "per_call"
"color:#b8ff57">listing.pricing.cost_per_call       // 0.001
"color:#b8ff57">listing.integration.auth_method     // "api_key_header"
INTEGRATESTEP 03

Call and execute

One structured listing = one integration. Auth, retries, and error normalization handled by the runtime. Your agent just calls.

example

result = "color:#b8ff57">indexa.call("color:#b8ff57">listing.id, {
  symbol: "AAPL",
  interval: "1d"
})
// → { price: 189.84, volume: 52_341_200 }
Why Indexa

Built for agents,
not browsers.

Agent-nativeA

Structured by default

Every service listing is typed JSON — not a webpage, not a PDF, not a sales deck. Inputs, outputs, auth method, pricing model, SLA. All machine-comparable.

FocusedB

Phase 1: data & finance APIs

Curated catalog of the best data and finance APIs. Fully indexed and comparable. Not 800+ noisy integrations — the right ones, done right.

FrictionlessC

Zero friction, free to start

No cost to agents during adoption phase. No API key negotiation. No sales calls. Query the catalog, pick a service, integrate. That's it.

The listing format

Every field is typed.
Nothing is ambiguous.

Indexa service listings are JSON Schema–validated objects. Controlled vocabularies on every field. No free-text descriptions that agents have to parse. Every listing is directly comparable to every other.
