How this service works
Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.
Output
A JSON object containing the provider name ('posthog'), the operation executed (e.g. 'capture'), and a data field with the raw PostHog API response confirming the operation result.
Example use cases
Agent action event tracking
“Every time our AI agent completes a task, send a 'agent_task_completed' event to PostHog with the task type and duration as properties — use the capture operation.”
Funnel step recording
“Record a 'signup_step_2_completed' event in PostHog for the user with distinct_id 'user_xyz' along with their plan type so we can track funnel drop-off.”
Error event logging
“Send an error event called 'api_call_failed' to PostHog with properties error_code: 503 and endpoint: '/api/v1/orders' so we can monitor failure rates in our PostHog dashboard.”
Technical details
Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/posthog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs to send PostHog analytics events (such as event capture) in a Web3-native, pay-per-call fashion using USDC on Base, without managing PostHog API keys or credentials directly. It is ideal for agent pipelines that already use x402 for micropayments and want to instrument user or agent behavior in PostHog without standing up a separate backend integration.
Side effects
- Invalid or unsupported operation name returns an error — only allowlisted PostHog operations are accepted
- Missing required input fields for the chosen operation may cause a PostHog-side rejection
- Payment failure or insufficient USDC balance prevents the call from being processed via x402
- Malformed input object properties may result in a PostHog validation error surfaced in the data field
- Network or PostHog API downtime can cause transient failures
