A deep dive into the end-to-end protocol flow by which autonomous AI agents discover, evaluate, and purchase DePIN data products via the Model Context Protocol—covering JSON-RPC registration, credit issuance, product listing, snapshot procurement, Stripe-mediated top-ups, and the cryptographic trust guarantees that make agent commerce viable.
DePIN data is the fastest-growing segment of our catalog. Solar, water, EV, telecom — the sensors are multiplying and the data is undervalued.
Rate limiting is necessary but dangerous — too aggressive and agents can't evaluate your data. Our adaptive rate limiting strategy that balances protection with access.
How AI agents interact with structured data — experiments, insights, and production lessons.
A deep technical exploration of data engineering principles at scale.
The 10 best bugs of 2025: the off-by-one that cost 800 records, the timezone bug that shifted all timestamps by 7 hours, and the ClickHouse query that ran for 4 days.

Our bulk insert optimization: async writes, batched commits, and the INSERT settings that got us to 1M rows/second on commodity hardware.
Normalizing DePIN metrics requires collapsing 89 distinct native field names into 38 canonical concepts with strict unit declarations. This article explores the schema mapping architecture, the 'same-question guarantee' enforced via hourly self-tests, and why rejecting ambiguous metrics is architecturally superior to shipping corrupted signals.
SQLite isn't supposed to handle production workloads at scale. We've been running it as our ingestion buffer for millions of daily signals. Here's what breaks and when.
Our battle-tested ClickHouse optimization guide: partition keys, ORDER BY, materialized views, and the 3 settings that most people get wrong.
No message queue. No orchestrator. 30 workers pull from a shared SQLite buffer and coordinate via timestamp watermarking. The architecture that scales.
