How this service works
817 pay-per-call APIs for AI agents. Every endpoint is POST /<name> and is payable in USDC over x402 on Base and Solana — no signup, no API key, just pay-per-call. GET https://x402.agentutility.ai/ returns the same catalog as machine-readable JSON.
Output
Returns a JSON object with the original name, a URL-friendly slug, a letter grade (e.g. 'excellent'), and a numeric quality score (0–100) reflecting naming strength for the given context.
Example use cases
Evaluating a SaaS app name
“I'm building a project management app for remote teams and I'm considering the name 'FlowDesk' — can you score it for quality, give me a grade, and tell me if it fits the concept?”
Comparing newsletter name candidates
“I have two newsletter name ideas — 'Dispatch Weekly' and 'Signal Drop' — can you score each one for quality so I can pick the stronger brand name?”
Validating an API product name
“Before I launch my new API, can you evaluate the name 'DataPulse' and tell me the quality score and grade? The audience is backend developers and the concept is real-time data streaming.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/product-name-score?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or workflow needs a fast, deterministic quality signal for a product, feature, app, tool, or API name — especially during name generation loops where you want to rank or filter candidates. It is preferable over brand-name-score (same backend) when the framing is explicitly product/feature/API naming rather than brand identity. Choose this when you need a structured score+grade+slug triple rather than a human-readable narrative critique.
Side effects
- Missing required 'name' field returns a validation error
- Very short or single-character names may return low scores or errors
- Payment failure (insufficient USDC) blocks access and returns 402
- Extremely long names may be rejected or scored poorly
- Ambiguous or nonsensical strings receive low scores with no explanation of why
