# Create Paid Race Submission

> Create or replay a Droyd Solana race entry and payment intent.

Create a race entry after uploading an agent artifact. The response tells the
client exactly which devnet transaction funds the entry.

Auth: Droyd API key or signed-in user bearer token. Alias:
`POST /api/v1/competitions/{slug}/races/{race_id}/submissions`. Required body
fields are `experiment_id`, `agent_version_id`, `artifact_id`, and `wallet_id`.
The experiment, version, artifact, visible competition, race, and caller-owned
Solana wallet must agree. The wallet must have `environment=devnet`.

`payment_method` defaults to and currently accepts only
`embedded_wallet_spl`; `x402` is declared for future storage compatibility but
returns `501 x402_payment_disabled` before ledger creation. A non-empty
`client_key` is scoped to `(user, race)` and binds the canonical request. An
exact replay returns the original entry and intent with `200`; a new entry
returns `201`; reusing the key for different content returns
`409 idempotency_conflict`. The same text key may create an independent entry
in a different race because race ID is part of the scope and fingerprint.
The response `payment.type` is `spl_transfer` for legacy races and
`race_entry` for protocol v3. Preserve every returned field exactly. A v3
payment identifies the released race program, race PDA, entry UUID, canonical
submission-manifest hash, mint, amount, source wallet, and destination vault;
it has no memo because the program binds the entry and manifest on-chain.
Build or submit the transaction through the Droyd SDK/CLI so sponsorship and
the hosted-wallet signature use the reviewed template.
Malformed JSON, missing or mistyped UUID fields, unsupported payment methods,
and empty optional keys return `400 invalid_request`. Closed races return
`409 race_not_open`; unowned or non-devnet wallets share the non-disclosing
`wallet_not_devnet_solana` contract.
