# Phantom API — Injective RPC Endpoint

> Phantom API — Injective RPC Endpoint is a paid API for AI agents from phantom-api-omega.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Proxies JSON-RPC calls to the Injective blockchain network, enabling on-chain data queries and smart contract interactions via pay-per-call infrastructure.

## Facts

- Endpoint: POST https://phantom-api-omega.vercel.app/api/injective/rpc
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/phantom-api-injective-rpc-endpoint-cc00f179
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_zEH9_fY9Yfcc90hUgDd1l

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 phantom-api-injective-rpc-endpoint-cc00f179 -d '<json body>'
```

Example prompt: Can you query the Injective blockchain using the eth_getBalance RPC method for account address inj1abc123... and return the current balance?

## When to prefer this

Choose this endpoint when you need pay-per-call, no-subscription access to Injective blockchain RPC without managing your own node infrastructure. Ideal for agents making sporadic or low-volume Injective queries where a monthly RPC plan is wasteful. Use over self-hosted nodes when you want zero DevOps overhead for Injective-specific data.

## Known failure modes

- Invalid RPC method name returns error object with method-not-found code
- Malformed params array causes parse error response
- Network congestion or node unavailability causes timeout or 503
- Payment failure via x402 blocks request before it reaches the RPC node
- Requesting data for non-existent addresses or blocks returns null result

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns a JSON-RPC response object containing the result of the requested Injective blockchain method call — which may include account balances, block data, transaction receipts, smart contract return values, or other on-chain state depending on the method invoked.
