# Clink Forge Bank Profile Lite

> Clink Forge Bank Profile Lite is a paid API for AI agents from api.clinkforge.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns a lightweight bank profile data record with cryptographic provenance and attestation for a given institution ID, sold per call via x402 micropayment.

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 clink-forge-bank-profile-lite-327c62ef
```

Example prompt: Pull the bank profile lite record for institution ID 'BOFAUS3N' — I need the data rows along with the provenance and attestation details.

## When to prefer this

Choose this endpoint when you need a lightweight, per-call bank profile lookup with built-in cryptographic provenance and attestation rather than a bulk or subscription data feed. Ideal for agentic pipelines that require machine-verifiable data integrity (Ed25519-signed records with source URLs and license IDs) and are comfortable with x402 micropayment settlement at $0.02 USDC per call. Prefer this over generic bank lookup APIs when auditability and data provenance are compliance requirements.

## Known failure modes

- Missing or invalid 'id' query parameter returns a 400 Bad Request
- ID exceeding 12 characters is rejected by schema validation
- Payment not settled via x402 protocol returns 402 Payment Required
- Unknown or unrecognized institution ID returns empty rows or 404
- Attestation signature mismatch may indicate data tampering or stale record
- Network or provider downtime returns 5xx error

## How this service works

Pay per call over x402. USDC on Base, no account, no API key. 28 government-sourced data products at $0.001–$0.05 per call, every response signed and provenance-chained.

## Output

A JSON response containing: one or more data rows with payload fields and record IDs, product metadata (slug and version), a provenance object (license ID, source URL, observation timestamp), a cryptographic attestation (Ed25519 algorithm and base64 signature), and a payment receipt with settlement reference. Together these provide machine-verifiable proof of data origin and integrity.
