Horse Truth / Machine Intelligence

Checking billing…

Autonomous machine access

Horse intelligence your software can buy and consume.

Australian horse and race intelligence for AI agents, MCP clients, publishers and software. No odds are used. Selections are sealed before the race and every miss is on the public record. Try any horse free, then pay per call with x402 or buy a reusable key.

No wallet? Get a card-paid key: A$1 for 50 calls

Pay once by card on Stripe. You get a reusable key for 50 calls. No crypto wallet needed.

Machine access

Free first: try any horse with /api/v1/sandbox/horse?name=Chance%20With%20Wolves. No key, no payment. Then pay per call with x402 and no account, from US$0.001 to resolve a horse and US$0.02 for a full read. The machine quickstart shows every step.

Marketplace paths: Horse Truth is public on RapidAPI, which handles keys and billing. The Apify actor is under maintenance on Apify and cannot be used right now. Use x402, RapidAPI or a direct key instead.

For reusable direct access, start with the A$1 / 50-credit pack below or choose monthly access. Automatic overage is on for monthly machine plans only. When a monthly plan's included credits run out, each further successful call is billed through Stripe at that plan's metered overage rate. One-time credit packs never go into overage. When their credits reach zero, paid endpoints return HTTP 402 until more access is bought.

Free sandbox

See the shape of Horse Truth intelligence before purchasing machine access.

GET /api/v1/sandbox/chance-with-wolves

Sandbox output appears here.

Authentication

After verified payment, Horse Truth returns your machine API key once.

Authorization: Bearer htm_your_key

# or
X-Horse-Truth-Key: htm_your_key

Horse Truth stores only a cryptographic hash of the key. Copy and secure the raw key when it is issued.

REST quick start

curl https://horsetruth.com.au/api/v1/horses/Chance%20With%20Wolves/intelligence \
  -H "Authorization: Bearer htm_your_key" \
  -H "Idempotency-Key: your-request-id"

One successful paid request consumes one credit. Reusing the same idempotency key for the same endpoint does not consume a second credit.

MCP

Scientific boundary

Machine billing controls access to intelligence. It does not control Horse Truth scientific conclusions, model promotion, Race Day publication or research authority. Raw provider data is not sold through this interface.

Horse Truth machine intelligence is a derived information service. Paying for access never changes a ranking, and Race Day selections are sealed separately. Not betting advice.
