# Delx Bridge Cost Budget

> Delx Bridge Cost Budget is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Aggregates gas, slippage, and bridge fee components into a total cross-chain bridge cost budget in USD.

## 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 delx-bridge-cost-budget-cebd1f50 -d '<json body>'
```

Example prompt: Can you calculate my total bridge cost budget given a gas cost of $1.20, a slippage budget of $0.30, and a bridge fee of $0.50?

## When to prefer this

Use this endpoint when an AI agent or workflow needs to programmatically aggregate the three standard components of a cross-chain bridge transaction (gas, slippage, bridge fee) into a validated, schema-versioned total cost object, especially when downstream logic depends on a structured cost breakdown rather than a simple sum.

## Known failure modes

- Missing or non-numeric input fields may cause validation errors or incorrect totals
- Negative values for cost components may produce unexpected results
- If any field is omitted the total may undercount actual bridge cost

## How this service works

Sum gas + bridge fee + slippage budget into total cost. Call when comparing bridge routes with known component costs. Returns total_cost and components as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object with the schema identifier 'delx/util-bridge-cost-budget/v1', a components object breaking down gas_usd, slippage_usd, and bridge_fee_usd as submitted, and a total_cost field representing their sum in USD.
