How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
Returns a JSON object with success status and a result object containing pricing and rate information for the requested AI model, resolved from a catalog via fuzzy name matching on the provided model name or alias.
Example use cases
Budget check before agent workflow
“Before I kick off this multi-step research pipeline, can you check what the current rate is for gpt-4o so I can estimate total costs?”
Compare model rates by alias
“Look up the pricing for 'sonnet' — I want to see its rate and make sure it matches what I'm being billed.”
Billing verification for model usage
“Can you fetch the official rate for claude-sonnet-4-5 and compare it against the charges showing up in my invoice?”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/model/lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically verify, budget, or audit the cost of calling a specific LLM model before or after invocation, especially when the model is referenced by a short alias or informal name that needs fuzzy resolution to a canonical catalog entry.
Side effects
- Model name not found in catalog — fuzzy resolution may fail for very obscure or misspelled aliases
- Missing required 'name' query parameter returns a validation error
- Service unavailable or 402 payment not processed results in no data returned
- Stale pricing data if the catalog is not updated in real time
