This server is a pay-per-use, transparent proxy in front of WithZero's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.","url":"https://agents.withzero.xyz/api/v1/audio/transcripts/gpt-4o-transcribe","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"audio":{"type":"string","maxLength":20971524,"minLength":1,"description":"Base64-encoded audio to transcribe (decoded size up to 15 MB)."},"format":{"enum":["wav","mp3"],"type":"string","description":"Container format of the audio."}}},"responseSchema":null,"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.3","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":{"amountUsd":"0.30","asset":"USDC"},"pricing":{"kind":"session","summary":"$0.3/call","primary":{"kind":"session","protocol":"mpp","network":"tempo","amountUsd":"0.3","per":"call","confidence":"exact","depositUsd":"0.30"},"accepted":[{"kind":"session","protocol":"mpp","network":"tempo","amountUsd":"0.3","per":"call","confidence":"exact","depositUsd":"0.30"},{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.3","per":"call","confidence":"exact"},{"kind":"unknown","protocol":"mpp","network":"tempo","amountUsd":null,"per":"call","confidence":"unknown"}]},"paymentMethods":[{"uid":"pm__Vx0TpJrosFWCMF5gGNSk","protocol":"mpp","methodType":"crypto","chain":"tempo","mode":"session","costAmount":"0.3","costPer":"request","priority":0,"asset":"0x20C000000000000000000000b9537d11c60E8b50","unit":"request","depositMicros":300000,"planRef":null},{"uid":"pm_VHhqIEPTGy5sPLLp7AMaE","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.3","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null},{"uid":"pm_yBLsMcqzFTWjgGg8D9c1Q","protocol":"mpp","methodType":"crypto","chain":"tempo","mode":"charge","costAmount":"unknown","costPer":"request","priority":0,"asset":null,"unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Transcribes base64-encoded audio (WAV or MP3, up to 15 MB) to text using OpenAI's GPT-4o transcription model, billed per call via ZeroClick's x402 payment layer.","exampleAgentPrompt":"Can you transcribe this MP3 audio clip for me?
