Lint agent tool schemas API

Find malformed JSON Schema and OpenAPI tool definitions in caller-supplied tools: bad types, required names that are not properties, empty enums, and duplicate tool names. Nothing is fetched.

The Lint agent tool schemas operation is part of the Agent Tool Schema Intelligence API on BRAINIAC.software. Find malformed JSON Schema and OpenAPI tool definitions in caller-supplied tools: bad types, required names that are not properties, empty enums, and duplicate tool names. Nothing is fetched. It is exposed as POST /api/v1/agent-tool-schema/tool-schema-lint 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 tool definitions, JSON Schema objects, and OpenAPI documents processed locally Limitations: No schema URL is fetched and no language model reads the text. Keyword checks cover JSON Schema draft-07, JSON Schema 2020-12, OpenAPI 3.0, and OpenAPI 3.1. Two tools are not treated as duplicates only because they share a few words. Token figures are characters divided by four, not a provider tokenizer. 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 Detect ambiguous tool schemas, Detect overlapping tool schemas, Validate tool request examples, Audit tool required fields.
