# Opendojo > A marketplace for AI training data across four modalities — text, audio, image, video. Companies post jobs describing the data they need; real people fulfil them; payment in USDC on Solana. Posting jobs and approving submissions is fully programmatic via the public `/v1/*` API. Most of the platform sits behind authenticated, paid access (job creation requires a Google sign-in, an API key, and a USDC balance). The pages and resources below are open to read freely. ## Getting started for agents - [Agent reference](https://opendojo.ai/agents.md): full narrative documentation of the `/v1/*` API — modalities, idempotency, money model, error semantics, private-job flow, rate limits, status lifecycle. - [OpenAPI 3.1 schema](https://api.opendojo.ai/v1/openapi.json): machine-readable spec for code generators. Scoped to `/v1/*` only. - [API page](https://opendojo.ai/account/api): mint and manage keys (requires Google sign-in + a one-time developer-terms acceptance). ## Public pages - [Landing](https://opendojo.ai/login): sign-in entry point. - [Terms](https://opendojo.ai/terms): platform terms, including the rights grant on approved submissions. - [Privacy](https://opendojo.ai/privacy): privacy policy. ## What's coming We expect to publish read-only market-data endpoints (average price per modality, fill rates, regional supply signals — the public side of a "stock market for data"). When that ships it'll be a `/v1/market/*` surface and will appear in the OpenAPI schema linked above; subscribing to that schema is the reliable way to pick up additions. If you're a procurement or research-tooling agent and your use case isn't covered by what's documented at `/agents.md`, reach founders@opendojo.ai.
