# Ailabra Agent Profit Ledger – Profit Attestation

> Ailabra Agent Profit Ledger – Profit Attestation is a paid API for AI agents from x402.ailabra.org, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15).

Submits economic events (revenue, expenses, fees, etc.) for a deterministic profit calculation and returns a cryptographically signed profit/cash-flow report for an autonomous agent.

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 ailabra-agent-profit-ledger-profit-attestation-f0bf93e2 -d '<json body>'
```

Example prompt: Record these economic events for my agent 'agent-007' under venture 'venture-xyz' — a $150.00 USDC revenue inflow from 'stripe' (receipt_verified) with external ID 'evt_001' that occurred at 2024-06-01T12:00:00Z in category 'subscription', and a $20.00 USDC fee outflow from 'openai' (system_observed) with external ID 'evt_002' — and give me back a signed profit attestation report.

## When to prefer this

Choose this endpoint when an autonomous agent needs a deterministic, cryptographically attested profit and cash-flow report — especially for compliance, auditing, or financial transparency of agent-operated ventures. Prefer this over generic bookkeeping APIs when you need Ed25519-signed, schema-versioned reports specifically designed for autonomous agent economics and x402 payment flows.

## Known failure modes

- Missing required fields (schemaVersion, externalId, occurredAt, kind, direction, amount, currency, category, source) result in a 400 validation error
- Invalid amount format (non-numeric or negative) causes schema validation failure
- Duplicate events detected via externalId + source.name combination may be rejected or deduplicated
- Unsupported currency code pattern causes rejection
- Invalid enum values for kind, direction, or source.verification return validation errors
- Payment failure or insufficient USDC balance returns 402 Payment Required
- Server-side calculation engine errors return 500 with no report

## How this service works

Deterministic profit and cash-flow infrastructure for autonomous agents.

## Output

A JSON object containing a signed profit/cash-flow report with a unique reportId, calculation engine version, schema version, and an Ed25519 digital signature attesting the deterministic profit calculation based on the submitted economic events.
