Analyze llms.txt context budget API

Measure caller-supplied llms.txt size, repeated lines, and repeated link paths. The token figure is characters divided by four, not a model tokenizer.

The Analyze llms.txt context budget operation is part of the llms.txt Intelligence API on BRAINIAC.software. Measure caller-supplied llms.txt size, repeated lines, and repeated link paths. The token figure is characters divided by four, not a model tokenizer. It is exposed as POST /api/v1/llms-txt/context-budget-analyze and priced at $0.03 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Caller-supplied llms.txt text, structured documents, and optional documentation pages processed locally Limitations: No URL is fetched, so a link is not treated as working or as proof a page exists. Scores subtract documented weights from 100. They are not a model grade. Contradiction and instruction checks match listed phrases only. Ordinary how-to text is not treated as an attack. Structured JSON is rendered to llms.txt lines before the same checks run. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings. Related operations in this group include Validate llms.txt structure, Check llms.txt link quality, Analyze llms.txt page coverage, Analyze llms.txt navigation.
