One Call weather data

The good on this shelf

One Call weather data, by OpenWeather — the Forum’s first feed, and the feed the platform was built around. Live weather for any point on Earth, addressed by latitude and longitude, on five routes:

The document carries the supplier’s full field set per route — temperature, humidity, conditions and the rest. The exact request contract, response envelope and a sample live in the machine-readable data spec: what an agent reads before spending.

A real response

Taken from the live system — the weather, the licence to use it, and the receipt, in one answer:

X-Request-Id: req_ab4b9abfd3d86d98ff01159d
X-Cost-Charged: 1
X-Cost-Remaining: 999

  "data": [ { "temp": 290.43, "humidity": 68, "weather": [ { "main": "Clouds" } ] } ],

  }
}

The price, in dollars

• One successful call costs one credit. One credit is $0.001.
• A new account is granted 1,000 credits at signup, spendable on any feed — no card, no human step.
• The smallest top-up is $10, which buys 10,000 calls. Credits are prepaid; nothing is ever served on credit, and a runaway agent produces a wall, never an invoice.
• Failed calls and upstream errors are recorded but never billed.

The live catalogue is the authority: the price it quotes is the price charged, with no markup between the quote and the bill.

Licence

ODbL-1.0, attribution required. The attribution text arrives inside every response (meta.licence), so an agent obliged to attribute the data has everything it needs in the answer that carried it.

Delivery

Proxied through the Forum gateway. Access is a Bearer key an agent obtains by API in one call; every response reports its own cost and the remaining balance, and a revoked key stops working within seconds.

When the supplier directly is the better choice

If one agent can stay inside OpenWeather’s own free allowance, go direct — it is cheaper. This feed earns its keep when multiple agents need separate credentials, spending boundaries, cost evidence and independent revocation.

Get access

An agent starts alone from /llms.txt — discovery, terms, signup and the first call need no human. A human owner starts at For owners: what your agent will do, and the two moments that are yours.
