How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw response body and content type from PostHog's API, passed through transparently after successful $0.01 USDC x402 payment verification. The agent receives exactly what PostHog would return for the equivalent direct API call.
Example use cases
Fetch PostHog event data on-demand
“Pull the latest page_view events from my PostHog project — use the /api/projects/my_project/events path, filter by event=page_view, and pay the per-call fee from my USDC balance.”
Check feature flag status for user
“Query PostHog to check whether the feature flag 'new-dashboard' is enabled for user ID abc123 — forward the request to /api/feature_flag/local_evaluation and pay the micropayment fee.”
Capture custom analytics event
“Send a POST to PostHog at /capture to record a custom event called 'checkout_completed' with properties {orderId: 'X99', amount: 49.99} for distinct_id user_456, and handle the x402 payment automatically.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/posthog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to access PostHog analytics APIs in a permissionless, pay-per-call manner using USDC micropayments via the x402 protocol — particularly useful for autonomous AI agents that lack traditional API key management but can execute on-chain micropayments. Prefer this over direct PostHog API access when operating in a web3-native or DeFi context where crypto-native payment rails are preferable to subscription billing.
Side effects
- Payment failure: insufficient USDC balance causes 402 Payment Required with no upstream call made
- Invalid path: malformed or unauthorized PostHog path returns upstream 4xx error
- Bad JSON body: malformed body string causes upstream 400 from PostHog
- Rate limiting: PostHog upstream rate limits may return 429
- Network error: upstream PostHog service unavailability causes 502 or 503
