How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with an 'ok' boolean indicating whether the username passed strong validation, and a 'paid' boolean confirming the x402 micropayment was processed. May include additional validation detail fields.

Example use cases

Pre-registration username check

“Before I create the account, can you verify that 'shadow_runner99' is a valid strong username? I want to make sure it won't be rejected.”

User-facing form validation

“A user typed 'j!' as their username in my signup form — does that pass strong username validation rules?”

Bulk onboarding username policy

“I'm migrating users and need to check if the username 'Alice.Wonderland2024' meets strong username requirements before importing it.”

When to prefer

Choose this endpoint when you need a lightweight, no-signup, pay-per-call username strength check via x402 micropayment on Base/USDC, especially when building autonomous agent workflows that must avoid OAuth or API-key management overhead. Prefer over bespoke regex solutions when you want a deterministic, hosted validation rule enforced consistently.

Side effects

Missing or empty schema/username parameter returns an error or false ok
Malformed input string may return validation failure
Payment failure (insufficient USDC balance) blocks the call entirely
Network timeout on the Cloudflare Worker edge node
