summary: >-
  Story Protocol publishes public, shared API keys for both mainnet and the
  Aeneid testnet, plus a testnet faucet. The Aeneid testnet is the sandbox
  environment for development; mainnet is production. Values below are published
  verbatim by Story's docs.
networks:
- name: Story mainnet
  chain_id: 1514
  x_chain: mainnet
  public_api_key: MhBsxkU1z9fG6TofE59KqiiWV-YlYE8Q4awlLQehF3U
  environment: production
- name: Aeneid testnet
  chain_id: 1315
  x_chain: aeneid
  public_api_key: KOTbaGUSWQ6cUJWhiJYiOjPgB0kTRu1eCFFvQL0IWls
  environment: sandbox
  faucet: https://aeneid.faucet.story.foundation/
rate_limit:
  public_key_rps: 300
  note: Public keys are limited to 300 requests/second; higher limits via the Builder Discord.
headers:
  X-Api-Key: one of the public keys above (or a higher-limit key)
  X-Chain: selects the network (see x_chain per network)
notes: >-
  These are Story-published shared public keys intended for open access, not
  secrets. No test-card / test-account fixtures apply (the API is a read-only
  on-chain IP indexer). Test writes are performed against the Aeneid testnet via
  the SDKs using faucet-funded wallets.
