Quick Start

Make your first metered RPC call in under two minutes — free tier, no account required.

1. Make a call with no key at all

The fastest way to understand Satelink is to call it. The free tier is gated by IP, not by account:

curl -X POST https://rpc.satelink.network/rpc \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

You get a normal JSON-RPC response. Free tier: 500 calls per day per IP (also capped per /24 subnet). When you exceed it, the gateway answers with HTTP 402 Payment Required — and the 402 body is self-contained: it tells you (or your machine) exactly how to register and deposit to continue. See Machine Customers.

2. Create an API key

An API key gives you your own metered quota and a usage dashboard. One call, no signup form:

curl -X POST https://rpc.satelink.network/api/keys \
  -H "Content-Type: application/json" \
  -d '{"label":"my-first-key","tier":"free"}'

The response contains your api_key (shown once — store it). Prefer a UI? The developer console creates a wallet-bound key from a single MetaMask signature.

3. Call with your key

curl -X POST https://rpc.satelink.network/rpc \
  -H "Content-Type: application/json" \
  -H "X-API-Key: YOUR_API_KEY" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

4. Check your usage

curl https://rpc.satelink.network/api/keys/usage \
  -H "X-API-Key: YOUR_API_KEY"

Returns your tier, daily limit, requests today, credits spent, and credits remaining.

5. Add credits (optional, for volume beyond the free tier)

Deposit USDT on Polygon PoS to the RevenueVault — permissionless, from any wallet. $1 buys ≈ 33,333 calls at the flat metered rate of $0.00003/call:

curl "https://rpc.satelink.network/credits/initiate?amount=10"

The response contains the vault address, the USDT contract address, and ready-to-send approve + deposit calldata. Credits appear after ~25 block confirmations (about 5 minutes). Full detail: Billing & Credits.

Supported chains

The gateway monitors every upstream provider with health checks and circuit breakers — see live provider status at rpc.satelink.network/rpc/health.
