Data Sources Catalog

Valyu gives one search interface over state-of-the-art web search plus specialised, proprietary, and open data sources spanning research, finance, life sciences, genomics, law, and more. This page is a tool manifest: a single place for an AI agent (or its developer) to learn what exists and exactly how to target it. You have three ways to control which sources answer a query:

Let us route

Call /search with no source filter and Valyu selects the most relevant sources automatically.

Target by id

Pass dataset ids (e.g. valyu/valyu-sec-filings) to included_sources to query exactly those datasets.

Target by preset

Pass a preset name (e.g. finance, genomics) to included_sources to query a whole family at once.

Integrating raw Search? If you are building knowledge work on top of these sources, consider DeepResearch instead - a cost-effective autonomous agent built on top of the same search engine that plans, runs, verifies, and writes a cited report for you. It uses every source below (including DeepResearch-only signals) without you orchestrating the calls.

How to target sources

The included_sources array on /search (and the underlying tooling in Answer and DeepResearch) accepts any mix of:

dataset id

string

A specific dataset, e.g. valyu/valyu-patents. Combine multiple ids to query several datasets together.

preset name

string

A family shortcut: academic, finance, patent, transportation, politics, legal, health, genomics, chemistry, physics, pulse, cybersecurity, environment, automotive, compliance, medical. Expands to every dataset in that family.

collection:NAME

string

An org-scoped saved source set. Create reusable bundles of sources in the platform, then target them by name, e.g. collection:diligence-stack.

web

string

The live web. Pass web to force web search alongside (or instead of) proprietary datasets.

url / domain

string

A specific URL or domain to bias web results toward, e.g. arxiv.org.

Use excluded_sources to remove a source, and source_biases (an object of source -> -5..+5) to soft-rank without hard filtering.

from valyu import Valyu

valyu = Valyu()

# By id
valyu.search(
    "kinase inhibitor selectivity",
    included_sources=["valyu/valyu-chembl", "valyu/valyu-pubchem"],
)

# By preset - whole chemistry family at once
valyu.search(
    "EGFR inhibitor resistance mechanisms",
    included_sources=["chemistry"],
)

# By saved collection
valyu.search(
    "Q3 earnings drivers for semiconductor names",
    included_sources=["collection:diligence-stack"],
)

curl -X POST https://api.valyu.ai/v1/search \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "EGFR inhibitor resistance mechanisms",
    "included_sources": ["chemistry"]
  }'

How access works

All plans include web search and open academic sources (arXiv, PubMed). Specialised and proprietary sources (SEC, patents, drug discovery, genomics, and the rest) unlock as you move up plans - and a plan also lowers your cost per credit. During the free trial every source is available so you can test before you commit. See pricing for the full source-to-plan breakdown, or request access to a specific dataset above your plan.

Two availability concepts to know:

Plan-gated - a source unlocks at a given plan (or with free trial credits). Marked below as the plan that unlocks it.
Access mode - whether a source answers raw /search (and Answer) calls, marked Search + Answer + DeepResearch, or is served only inside DeepResearch, marked DeepResearch only.

DeepResearch-only sources can’t be called via /v1/search. Passing their ids to included_sources on /search returns no results. To use them, run a DeepResearch task (POST /v1/deepresearch/tasks) with the topic in the query; the agent pulls these signals automatically, and you can name the source to nudge it (e.g. “…using OFAC SDN and UK HMT sanctions lists”). Every other source below answers raw Search, Answer, and DeepResearch.

DeepResearch-only families and datasets at a glance

Whole families (every source) - not callable via /v1/search:

Transportation - UK National Rail, global ship tracking (AIS)
Environment & geo - NWS Weather, OpenAQ, FEMA Disasters, NASA EONET, Open-Meteo (+ air, marine), OSM Nominatim
Automotive - NHTSA vPIC, Recalls, Complaints, Investigations
Compliance & sanctions - OFAC SDN / non-SDN, UN, UK HMT, Swiss SECO, Australia DFAT, INTERPOL Red, US CSL
Pulse signals - GDELT, Wikipedia Pageviews, Crossref Velocity, PyPI / npm / crates.io downloads

Specific datasets inside otherwise-searchable families:

Finance - short-seller reports, buyside letters & pitches, semiconductor-industry news, congressional research (CRS), legal & regulatory news, FDIC BankFind
Health - NPI registry, WHO ICD, openFDA device events, openFDA food recalls, CDC wastewater (NWSS)

Everything else - web, academic, SEC, patents, chemistry, genomics, economics, prediction markets, UK case law / legislation / Parliament, physics, cybersecurity, and the searchable health/finance datasets - answers raw Search and Answer too.

Discover sources at runtime

Agents should not hardcode this list. Query the Datasources API to discover what is available, with example_queries (optimised for few-shot prompting), response_schema, and pricing.cpm per source:

import requests

datasources = requests.get(
    "https://api.valyu.ai/v1/datasources",
    headers={"x-api-key": "YOUR_API_KEY"},
).json()["datasources"]

curl https://api.valyu.ai/v1/datasources \
  -H "x-api-key: YOUR_API_KEY"

Filter to a category with ?category=markets, or list categories with counts at /v1/datasources/categories. This turns Valyu from “an API you need to know” into “an API that teaches itself to your agent.”

Targeting DeepResearch-only sources

Sources badged DeepResearch only are not callable from /v1/search - passing their ids to included_sources returns no results. Put the topic in a DeepResearch task instead and, optionally, name the source to steer it. The access mode lives in each dataset’s access_modes field from /v1/datasources, so agents can check it at runtime.

from valyu import Valyu

valyu = Valyu()

task = valyu.deepresearch.create(
    query="Screen Acme Shipping against OFAC SDN, UN, and UK HMT sanctions lists and summarise any matches.",
)
report = valyu.deepresearch.wait(task.id)

curl -X POST https://api.valyu.ai/v1/deepresearch/tasks \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "Track current vessel positions for Maersk container ships near the Suez Canal using global ship tracking."
  }'

Teach your agent to discover and target Valyu data sources correctly.
