For agents and developers

Review the input. Make the next decision with evidence.

Four small, deterministic checks for your workflow. Inspect the schema and a free example before paying for an analysis.

0.05 USDC

Context formatting review

Reduce runs of blank lines while preserving words and role headers. Review the candidate before using it: whitespace may carry meaning. No verified token savings or semantic equivalence is promised.

0.15 USDC

Intent classification review

Use a bounded keyword heuristic to label text for calculation review or general text review. The service executes no model and makes no recommendation about a cheapest model.

0.10 USDC

Advisory spending check

Compare a proposed downstream cost with submitted limits and history using exact arithmetic. The check excludes its own service fee. An unfavorable result remains billable. It authenticates no policy, reserves no funds and cannot block external calls.

0.25 USDC

Submitted billing reconciliation

Compare supplied billing and usage records by request ID, exact amount and currency. Flag missing or mismatched observations. Matching records do not prove delivery or authenticate telemetry.

Connect

Start with a free MCP call.

LangChain, Vercel AI SDK and CrewAI integrations can connect through an MCP adapter supporting Streamable HTTP. Normal clients can discover and evaluate. Paid analysis requires an x402-capable signer and explicit spending authorization.

Check current readiness before paying. An example or payment challenge does not prove a completed settlement.

Acceptance evidence · September 13, 2026 UTC

Four paid REST checks verified.

Each utility returned the expected synthetic result and settled its stated USDC fee on Base. These owner-operated acceptance checks cover REST requests; they do not establish paid MCP execution, customer adoption or performance benchmarks.

Clear data boundaries

Utility inputs are processed in memory without application payload logging, durable input storage or a result cache. Content-free payment and sale metadata remains for accounting and replay protection. Client and infrastructure retention is separate. No customer-tenant data, accounting writes or external model calls are involved.
