## Setup (MUST complete before making any API calls)

You need at least one payment method configured. **DO NOT call any Mesh tool APIs until setup is verified.**

### Step 1: Choose a payment method

**Option A: Heurist API Key (Recommended — simplest)**

1. Get an API key via ONE of:
   - Purchase credits at https://heurist.ai/credits
   - OR Claim 100 free credits via tweet (see [references/heurist-api-key.md](references/heurist-api-key.md))
2. Store the key in `.env` in the project root:
   ```
   HEURIST_API_KEY=your-api-key-here
   ```
3. All API calls use `Authorization: Bearer $HEURIST_API_KEY`

**Option B: x402 On-Chain Payment (USDC on Base)**

1. You need a wallet private key with USDC balance on Base.
2. Store the key in `.env` in the project root:
   ```
   WALLET_PRIVATE_KEY=0x...your-private-key
   ```
3. See [references/x402-payment.md](references/x402-payment.md) for the payment flow using `cast` (Foundry).

**Option C: Inflow Payment Platform (USDC via Inflow)**

1. If you already have Inflow credentials, store them in `.env`:
   ```
   INFLOW_USER_ID=your-buyer-user-id
   INFLOW_PRIVATE_KEY=your-buyer-private-key
   ```
2. If not, create a buyer account and attach email — see [references/inflow-payment.md](references/inflow-payment.md) for one-time setup.
3. Inflow uses a two-call payment flow (create request → user approves → execute). See [references/inflow-payment.md](references/inflow-payment.md) for the full flow.

### Step 2: Verify setup

Check that credentials are configured before proceeding:

- **API Key path:** Read `.env` and confirm `HEURIST_API_KEY` is set and non-empty.
- **x402 path:** Read `.env` and confirm `WALLET_PRIVATE_KEY` is set, starts with `0x`, and is 66 characters.
- **Inflow path:** Read `.env` and confirm `INFLOW_USER_ID` and `INFLOW_PRIVATE_KEY` are set and non-empty.

**If neither is configured, STOP and ask the user to set up a payment method. Do not make API calls without valid credentials.**

### Step 3: Make API calls

Once you have either Heurist API key or x402 wallet private key or Inflow key, you can make API calls. You should understand the tool schema and the parameters of tools you want before calling it.

To fetch tool schema, use `mesh_schema` API:

```
GET https://mesh.heurist.xyz/mesh_schema?agent_id=TokenResolverAgent&agent_id=CoinGeckoTokenInfoAgent
```
Default pricing is in credits. 1 credit worth $0.01. Add `&pricing=usd` to get prices in USD instead of credits when using x402 or Inflow. Returns each tool's parameters (name, type, description, required/optional) and per-tool price.

Then use the credentials in requests:

```bash
# With API key
curl -X POST https://mesh.heurist.xyz/mesh_request \
  -H "Authorization: Bearer $HEURIST_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"agent_id": "TokenResolverAgent", "input": {"tool": "token_search", "tool_arguments": {"query": "ETH"}, "raw_data_only": true}}'

# With x402 — sign with cast (Foundry), no account or SDK needed
# See references/x402-payment.md for the full cast-based flow and helper script
```
