Output
Returns an analysis of detected biases in the input text, likely including bias type labels (e.g. political, confirmation, framing), confidence scores, and possibly flagged phrases or spans that contribute to the detected bias.
Example use cases
Fact-checking news article bias
“I want to know if this article excerpt is politically biased — can you analyze it? 'Progressive lawmakers pushed through sweeping reforms today, ignoring concerns from fiscal conservatives who warned of skyrocketing deficits.'”
Reviewing corporate PR for spin
“Can you scan this press release for any obvious corporate bias or spin before I publish it? The text is: 'Our revolutionary product is transforming the industry, leaving outdated competitors scrambling to catch up.'”
Checking student essay for loaded language
“I'm a teacher and I want to flag any biased language in this student essay paragraph before grading it. Here's the excerpt: 'The greedy landlords exploited vulnerable tenants while corrupt politicians looked the other way.'”
Technical details
Endpoint
POSThttps://api.fastapi.online/bias-detectWhen to prefer
Choose this endpoint when you need a fast, per-call, no-signup bias detection service without committing to a SaaS subscription. Especially useful for agents processing individual text snippets for bias signals, content moderation pipelines, or research workflows where crypto micropayments are acceptable. Prefer over general-purpose LLM prompting when you want a dedicated bias classification model output rather than free-form LLM opinion.
Side effects
- Empty or missing text field returns validation error
- Text exceeding 8000 characters rejected
- Ambiguous or very short text may produce low-confidence or inconclusive results
- Non-English text may yield inaccurate results depending on model support
- Payment failure via x402 protocol results in 402 response before processing
