GET /v1/verify/http checks a URL is alive (redirect chain, TLS, latency, body hash). GET /v1/verify/dns resolves records and parses SPF/DMARC/DKIM. Email: POST /v1/verify/email/inbox issues a seed address; send mail to it, then GET /v1/verify/email?inbox=&token= returns delivery plus SPF/DKIM/DMARC alignment and raw headers (polls inside the paid window are free). Webhooks: POST /v1/verify/webhook arms a tripwire URL; register it upstream, then poll GET /v1/verify/webhook/{id}?token= for free. GET /v1/verify/page renders a page in a real browser, asserts a selector/text, and returns a screenshot URL. Failed work is never settled.","url":"https://verify.reversecaptcha.fun/v1/verify/email/inbox?utm_source=zero.xyz","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"ttl_hours":{"type":"number","maximum":72}}},"responseSchema":{"type":"json","example":{"inbox":"check-7f3a1b2c","token":"inb_...","address":"check-7f3a1b2c@inbox.example","verdict":"issued","expires_at":"2026-01-01T00:00:00Z"}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.001","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":null,"pricing":{"kind":"static","summary":"$0.001/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_j57jSttAv4MbOM7Fz0xjY","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.001","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Issues a disposable seed email address that an agent can receive mail to, then check for delivery confirmation with SPF/DKIM/DMARC alignment","exampleAgentPrompt":"Set up a temporary verification inbox that lasts 48 hours so I can send a test message to it and confirm my email system is delivering correctly with proper authentication.","exampleUseCases":[{"title":"Transactional email deliverability check","prompt":"Before I launch my newsletter, provision a seed inbox valid for 24 hours so I can send a test message and confirm it lands with passing SPF, DKIM, and DMARC."},{"title":"SMTP pipeline smoke test","prompt":"I just reconfigured my SMTP server — can you create a temporary inbox for the next 12 hours so I can fire a test email and prove the whole sending pipeline is working?"},{"title":"Support inbox for an agent fleet","prompt":"My agent needs to verify it can actually deliver email on behalf of users — set up a disposable inbox that lives for 48 hours so it can send to it and check alignment before going live."}],"resultDescription":"Returns a JSON object containing: inbox name/ID (e.g. 'check-7f3a1b2c'), a bearer token for subsequent poll calls, the full email address to send mail to (e.g. 'check-7f3a1b2c@inbox.example'), a verdict of 'issued', and an expiry timestamp.
