Architecture & value

The Promise

We solved the three core frictions that break autonomous agent data monetization.

Pain 01

Every data seller means another integration

Unified Single Endpoint

Zero vendor SDK sprawl. Send any data query to PulsRouter with standard parameters. We handle provider discovery, header negotiation, and response unwrapping.

Pain 02

A seller goes down, your agent stalls

Automated Multi-Provider Fallback

On rate limits, 5xx downtime, or latency spikes, PulsRouter instantly fails over to the next healthiest candidate in under 40ms.

Pain 03

The data bill arrives as a surprise

Granular Hard Spend Caps

Set deterministic ceilings per domain in pulsrouter.config.json ($5 research, $1 markets). Calls over budget fail safe locally before on-chain signing.
