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 estimated token count for the described HTTP request/response pair, enabling the caller to anticipate cost in USDC before actually executing and paying for the call via x402.
Example use cases
Pre-flight cost check for agent task
“I want to know the token cost estimate before sending this JSON request body to a Delx pay-per-result API — the input body is {"symbol": "ETH", "interval": "1h"} and the output example looks like {"price": 0, "volume": 0}.”
Budget planning for autonomous agent loop
“My agent is going to make hundreds of calls to a Delx Commerce endpoint in a loop — can you estimate the token cost per call given a form-data input body like {"text": "summarize this article"} and an expected JSON output like {"summary": "..."}?”
Comparing token cost across request formats
“Can you estimate how many tokens a Delx Commerce x402 API call would use if I send a text-type body saying 'translate this sentence to French' and expect a JSON response like {"translation": "..."}?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/token-estimate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to preview or budget the token cost of a Delx Commerce pay-per-result API call before actually executing it and paying. Ideal for autonomous agents that need cost-awareness before committing USDC via x402, or for developers testing and optimizing request payloads to minimize per-call expense.
Side effects
- Missing required 'input' or 'output' fields returns a 400 validation error
- Invalid bodyType enum value (not 'json', 'form-data', or 'text') causes schema rejection
- Empty or malformed body object may yield inaccurate or zero token estimates
- Network timeout if the estimation service is temporarily unavailable
- Invalid input type (not 'http') returns a constraint violation error
