Isocast bronze

isocast.dev

“Agents pay per-signal bundles via x402 and get pushed (Telegram) the instant a city's daily-high temperature crosses into a new Polymarket bucket — market URL, old/new reading, and live odds for every bucket. 37 cities. Free endpoints (cities, sample, pricing, terms) need no auth; deeper signal reads are paid per bundle via x402 (USDC on Base).

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of isocast.dev controls every word below.

Polymarket weather-market bucket-transition signals

Per-signal, bundle-prepaid alerts fired the instant a city's daily-high temperature crosses from one Polymarket temperature bucket into another. Each signal carries the market URL, the old and new reading + bucket, and live YES/NO/midpoint odds for every bucket (with a `dead` flag on unreachable buckets). Buy the next N signals for a city via x402 (USDC on Base, tiers from $0.005 down to $0.0035/signal, $0.01 minimum), then pull them from /v1/signals or have them pushed to Telegram. At-most-once per (city, day, bucket); seq is monotonic per city. 37 cities.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: Isocast — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.1.0
Extensions: x402 https://github.com/google-a2a/a2a-x402/v0.1
Paid endpoints settle via the x402 protocol (on-chain USDC). On an unpaid paid-route request the server returns HTTP 402 whose accepts[] lists one exact USDC rail per network; sign one rail and retry with PAYMENT-SIGNATURE (x402 V2) or X-PAYMENT (legacy).

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
