# Gas Price Oracle

`POST /v1/gas-price-oracle`

## Request

- Base URL: `https://agent.pocket.network`
- URL: `https://agent.pocket.network/v1/gas-price-oracle`
- Auth: none required

Multi-chain gas price oracle: current base fee plus priority-fee tiers for EVM chains. POST /v1/gas with {chain_id} and get the base fee and slow/standard/fast tiers as one JSON object. Deterministic per read instant. Pay per request in USDC; no account, no API key.

## Request body

- object: The chain to price.
  - `chain_id` integer, required: EVM chain id (default 1).

## Response `200`

The upstream response, served after payment settles.

- object: For POST /v1/gas, a JSON object with the base fee, priority-fee tiers, and the chain_id. The exact shape is the service's own and is not pinned here; errors return a JSON object with an `error` field, and the GET routes return their own small JSON documents.

## Other responses

- `400`: Malformed request.
- `402`: Payment required. The x402 v2 terms are in the PAYMENT-REQUIRED header and, identically, in this body; sign the chosen option and retry with the PAYMENT-SIGNATURE header. The receipt arrives in PAYMENT-RESPONSE.
- `503`: This service is not currently available to serve.
