This Acceptable Use Policy ("AUP") applies to all access to and use of Valyu's APIs, datasets, models, indexes, and related services (the "Services").
By using the Services, you agree to comply with this AUP. Valyu may update this AUP at any time, and your continued use of the Services constitutes acceptance of the updated version.
1. Definitions
1.1 Restricted Partner Content
"Restricted Partner Content" means any content, data, metadata, text, images, tables, charts, figures, abstracts, summaries, references, or other materials made available through the Services that are licensed to Valyu by third-party rights holders ("Partners", "Partner"), including publishers, data providers, aggregators, or research organisations, and that are subject to contractual use restrictions imposed by those Partners.
Restricted Partner Content includes, without limitation, Outputs, snippets, citations, metadata, summaries, extracted entities, or any other derived material that incorporate, reference, or are generated using such Partner-licensed content, whether provided directly by Valyu or surfaced through Valyu's APIs.
2. General Principles
You may use the Services only for lawful purposes and in accordance with this AUP, the Platform Service Agreement, and all endpoint-specific documentation.
You are responsible for all activity performed under your API keys.
3. Prohibited Uses
You may not use the Services to:
3.1. Illegal, Harmful, or Abusive Activity
Break any applicable law or regulation
Harm, threaten, or harass individuals
Generate or distribute malware or security exploits
Impersonate individuals or entities
Access or use the Services in ways that could damage or impair Valyu systems
4. Content Restrictions
You may not use the Services to:
4.1. Circumvent Rights, Copyrights, or Licensing Restrictions
Reproduce or redistribute copyrighted content
Access content behind paywalls or access controls
Store or display publisher content in ways not allowed by licensing
Extract, store, or manipulate full-text articles from licensed sources
Use the Services to access data you are not legally entitled to
4.2. Build, Recreate, or Compete with Datasets
You may not:
Rebuild, replicate, or simulate any Valyu corpus, dataset, index, or scoring
Join Outputs to reassemble source materials
Scrape or bulk download data via high-volume search queries
Perform "benchmark dumping" (large-scale exporting of output)
4.3. Use Outputs to Create Derived or Competitive Products
You may not:
Develop search engines, RAG corpora, knowledge bases, embeddings, LLMs, datasets, indexes, or generative models that compete with Valyu
Use Outputs as seeds for synthetic data that replicates licensed or indexed content
Use Outputs to build evaluation datasets for model training without written permission
5. Model Training & Machine Learning Restrictions
This is a zero-tolerance category due to Partner obligations.
You may not, under any circumstances, use:
Outputs
Citations
Summaries
Metadata
Extracted entities
Annotations
(or any other content returned by Valyu)
for any machine-learning-related activity described below.
5.1. Prohibited Training, Fine-Tuning, Pre-Training, and Distillation
You may not use any Valyu content or publisher content to:
Train, fine-tune, pre-train, adapt, or calibrate any machine learning model
Train or update:
Large Language Models (LLMs)
Embedding or retrieval models
Classifier or ranking models
Evaluation or reward models
Synthetic data generators
Perform model distillation, compression, imitation or behavioural replication
5.2. Prohibited Dataset Construction and Vectorisation
You may not:
Embed Outputs into a vector store
Create, augment, or curate datasets partially or wholly derived from Outputs
Generate synthetic corpora seeded by Outputs
Store Outputs or derivatives in structured or unstructured datasets
Feed Outputs into agentic retraining loops, auto-labelling systems, or RL pipelines
5.3. Use Valyu Outputs in Model Evaluation Pipelines
(e.g., to test or tune the performance of your own models)
Unless expressly authorised by Valyu in writing.
6. Contents Endpoint — User Responsibility for Third-Party URLs
6.1. Your Obligations When Submitting URLs
The Contents API endpoint (/v1/contents) extracts and processes content from URLs that you provide. By submitting any URL to the Contents endpoint, you represent and warrant that:
(a) You have reviewed and are in compliance with the terms of service, acceptable use policy, and any other applicable usage terms of the target website or service from which content will be extracted.
(b) You have reviewed the target website's robots.txt file and any other machine-readable access directives (including but not limited to X-Robots-Tag HTTP headers and <meta name="robots"> directives) and have confirmed that automated extraction of the requested content is not prohibited by those directives.
(c) Your use of the extracted content complies with all applicable copyright, intellectual property, data protection, and other laws in the jurisdictions in which you and the target website operate.
6.2. Valyu's Role
Valyu processes URLs submitted by you as a technical service provider. Valyu does not independently verify the terms of service or access permissions of third-party websites submitted via the Contents endpoint. You — not Valyu — are the party responsible for ensuring that your use of the Contents endpoint in connection with any given URL is lawful and authorised.
6.3. Indemnification
You agree to indemnify and hold harmless Valyu, its officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, costs, or expenses (including reasonable legal fees) arising out of or relating to your submission of URLs to the Contents endpoint in violation of this Section 6 or any third-party rights.
6.4. Prohibited Uses of the Contents Endpoint
Without limiting the generality of Section 3 and Section 4 above, you may not use the Contents endpoint to:
Systematically extract content from a single domain or set of domains at a scale or frequency that constitutes scraping, crawling, or harvesting
Access or extract content from URLs that you know or reasonably should know are protected by terms that prohibit automated access or extraction
Reconstruct, mirror, or archive a substantial portion of any third-party website or dataset
Extract content for the purpose of repackaging and redistributing it as your own, or in a manner that competes with the source website
Copy
any Restricted Content.
All Restricted Content must be discarded once the request completes.
7.2. Open Access (OA) & Open Web Content
You may temporarily cache Outputs only within the durations specified by Valyu's Documentation.
You may not:
Store Outputs indefinitely
Store Outputs in volumes sufficient to recreate datasets
Store large batches of outputs from related queries
Store Outputs outside the permitted cache window
8. Automated Usage & Query Behaviour
You may not:
Generate abusive query patterns (keyword enumeration, brute-force term scanning)
Run high-volume queries intended to perform scraping or bulk extraction
Use bots to obtain data at a scale that mimics crawling or harvesting
Perform load testing without prior written approval
Perform adversarial prompts designed to bypass licensing or content restrictions
Valyu may rate-limit, throttle, or block usage that appears harmful or potentially abusive.
9. Security Restrictions
You may not:
Reverse engineer or attempt to extract Valyu's models, indexes, embeddings, or scoring logic
Probe, scan, or test the security of systems without authorisation
Interfere with or disrupt the integrity of the Services
Attempt to bypass geographical, licensing, or content-access restrictions
10. Misrepresentation & High-Risk Use Cases
You may not:
Use Outputs as factual without verifying the underlying sources
Provide medical, legal, financial, or regulatory advice based solely on Outputs
Use Outputs in automated decision-making without adequate human oversight
Misrepresent Valyu's data as proprietary to your own organisation
11. Competing Use
You may not:
Use the Services to build competing APIs, search layers, indexing systems, or retrieval infrastructures
Benchmark Valyu for publication without written consent
Use knowledge of Valyu's performance or datasets to circumvent or replace the Services
12. Enforcement, Suspension & Termination
Valyu may:
Suspend or terminate access immediately
Revoke keys
Block IPs
Throttle usage
Notify rights holders
Take legal action
for any suspected or confirmed violation of this AUP.
We may also:
Update this AUP at any time
Change endpoint rules at any time
Modify caching and retention policies without notice
