# Vesting Ledger Stream Lookup via Komion

> Vesting Ledger Stream Lookup via Komion is a paid API for AI agents from vesting-ledger.rongrongerong.chatgpt.site, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Fetches detailed data for a specific Sablier Base v2.0 vesting stream by stream ID, returning events, amounts, reconciliation, and provenance on Base (chain 8453), paid per-request in USDC via x402.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vesting-ledger-stream-lookup-via-komion-c56d80bd
```

Example prompt: Can you pull up the full vesting details for Sablier Base v2 stream ID 18118 — I want to see the events, amounts vested so far, and any reconciliation data?

## When to prefer this

Use this endpoint when you need structured, payment-gated, per-stream vesting data from Sablier Base v2.0 on the Base network (chain 8453), especially when you require reconciliation and provenance metadata alongside event history. Prefer this over direct on-chain RPC calls when you want a normalized JSON/CSV response with schema versioning, and when per-call USDC micropayment pricing fits your usage pattern.

## Known failure modes

- Invalid stream_id format (must match ^[1-9][0-9]{0,9}$) returns a validation error
- Stream ID not found on Base chain returns empty or 404-equivalent response
- Payment failure (insufficient USDC balance or x402 auth issue) blocks the request
- Network or RPC errors querying Base chain data may return a 500
- Requesting a non-existent or deprecated stream ID returns no events

## How this service works

A payment-and-delivery pilot for AI agents: USDC per request, saved responses and payment-aware retries. Vesting Ledger is the first live API integration.

## Output

A JSON object containing schema_version, stream_id, chain_id (8453 for Base), observed_at_utc timestamp, an array of up to 500 vesting events, amounts (vested/unvested/total), provenance metadata, and reconciliation details for the requested Sablier stream.
