# Bindler API

The Bindler API runs three regulation calculators as JSON endpoints: EU AI Act risk classification under Regulation (EU) 2024/1689, CBAM certificate cost for a basket of goods from 2026 to 2034 under Regulation (EU) 2023/956, and UAE Corporate Tax for a tax period under Federal Decree-Law No. 47 of 2022. Each calculator accepts either query parameters or a JSON body and returns a facts-only result with the cited legal instrument. It is the same code behind the free browser tools at bindler.co, not legal or tax advice.

## For AI agents

Run three regulation calculators as JSON: classify an AI system under the EU AI Act, compute CBAM certificate cost for 2026 to 2034, and compute UAE Corporate Tax, each callable by query or JSON body across 9 endpoints with the cited instrument in every response.

## Scope

Does not file returns, give legal or tax advice, or store your submissions. Use for computing EU AI Act, CBAM, and UAE Corporate Tax figures only.

## Capabilities

- Classify an AI system's risk tier under the EU AI Act (Regulation 2024/1689)
- Compute CBAM certificate cost for a basket of goods for 2026 to 2034
- Compute UAE Corporate Tax for a tax period under Federal Decree-Law 47 of 2022
- Call each calculator by GET query parameters or by a JSON POST body
- Read the cited legal instrument returned with every computation

## Use cases

### Check EU AI Act obligations through Jentic

Determine how the EU AI Act applies to a given AI system before shipping it. The agent submits the system's purpose and attributes and reads back its risk tier under Regulation (EU) 2024/1689 with the cited articles, as a facts-only computation. Through Jentic the classifier is discovered by intent and called with its input schema, so the check fits into a compliance workflow.

Example prompt: Classify an AI system with POST /ai-act-classify and read the resulting risk tier and cited instrument

### CBAM certificate cost estimation

Estimate the cost of CBAM certificates for imported carbon-intensive goods across the 2026 to 2034 phase-in. The agent submits a basket of goods and a target year and gets the certificate cost with its cited instrument, so an importer can budget for the mechanism.

Example prompt: Compute certificate cost with POST /cbam-cost for a basket of goods and a target year

### UAE Corporate Tax computation

Compute UAE Corporate Tax for one tax period under Federal Decree-Law No. 47 of 2022. The agent submits the period's figures and gets the tax owed with the cited articles, so a finance team can sanity-check a provision as facts rather than advice.

Example prompt: Compute the tax with POST /uae-corporate-tax for one tax period

## Why Jentic

- **Setup:** Wiring Bindler by hand means learning its optional API key, choosing the header or query form of the key, and matching each calculator's input shape. Through Jentic you install once, import Bindler from the API Directory, store the key once, and your agent calls it.
- **Permission scoping:** Bindler's calculators take their inputs as query parameters or a JSON body, so a rule bounds which operations your agent may call, not which figures it computes. You can allow just the EU AI Act classifier while leaving the tax calculators out unless you add them.
- **Credential handling:** Your Bindler API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
- **Discovery method:** Agents search Jentic by intent such as 'classify an AI system under the EU AI Act' or 'compute CBAM cost', and Jentic returns the matching Bindler operation with its input schema so the agent calls the right endpoint without reading the reference docs.

## FAQ

### What authentication does the Bindler API use?

The Bindler API authenticates with an API key sent either in the `x-api-key` header or as a `key` query parameter, per its OpenAPI spec. A free tier allows unauthenticated use up to a daily cap per IP, and a paid key raises the limit. Through Jentic the key is stored encrypted by your own Jentic One instance and injected at call time.

### Can I classify an AI system under the EU AI Act with the Bindler API?

Yes. Send the system's attributes and Bindler returns its risk tier under Regulation (EU) 2024/1689 along with the cited articles. The result is a facts-only computation, not legal advice.

### Can I limit what my agent is allowed to do with the Bindler API?

Yes. Write a rule that allows only the EU AI Act classifier, so your agent can check AI-system risk tiers but cannot call the CBAM or UAE Corporate Tax calculators unless you add them. Bindler reads its inputs from the query string or JSON body, so rules bound which calculator runs, not the figures returned.

### What are the rate limits for the Bindler API?

The free tier allows 25 calls a day per IP with no account, as stated in the API description, and an unlimited key is available from Gumroad for a monthly fee. Check the Bindler documentation at https://bindler.co/api/ for current terms.

### Is there a Bindler MCP server?

You don't need an MCP server to give your agent Bindler. Jentic connects it directly from the API Directory: import it, store your key once, and your agent runs the three calculators on demand. That also keeps extra tool definitions out of the agent's context.

### How do I classify an AI system with the Bindler API through Jentic?

Search Jentic for 'classify an AI system under the EU AI Act' and it returns the Bindler classifier operation with its input schema. Your agent submits the system's attributes and reads back the risk tier and cited instrument. To run it on your own infrastructure, install Jentic One from its GitHub repo.
