How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the final text with the suffix guaranteed present, the suffix that was checked, and a boolean flag indicating whether the suffix was already present before the call.
Example use cases
Normalize file extension before upload
“I have a list of filenames from user input and I need to make sure they all end with '.csv' before I upload them — can you ensure each one has the right extension?”
Ensure URL path trailing slash
“The API path I'm building is '/api/v1/users' and it needs to end with a forward slash '/' — can you add it if it's not already there?”
Standardize config key suffix
“I'm generating config keys and they all need to end with '_config'. Can you check my string 'database' and append '_config' if it's missing?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/ensure-suffix?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, reliable, pay-per-use utility to enforce suffix presence on strings — especially in agentic pipelines where file naming, URL construction, or key normalization requires consistent formatting without setting up custom logic. Ideal when no signup overhead is acceptable and verifiable micro-payments via USDC are preferred.
Side effects
- Missing required 'text' or 'suffix' fields returns a validation error
- Empty string inputs may return unexpected results
- Payment failure via x402 protocol blocks the request
- Network timeout if the service is temporarily unavailable
