YOUR USE CASE. YOUR DATA CONTRACT.

A feed defined by your build.

Start with the decision your application needs to support. Define the records and evidence around it.

Custom feed planning brings technical requirements and commercial boundaries into one reviewable brief. No generic price or sample format can establish the coverage, rights, or delivery arrangement your project needs.

What to define

01 / FIELD OF VIEW

Define the universe

Name networks, native assets, token identifiers, and evidence relationships.

02 / FIELD OF VIEW

Choose the data contract

Specify fields, time semantics, history, corrections, and missing-value behavior.

03 / FIELD OF VIEW

Validate a useful sample

Agree acceptance cases, delivery recovery, permitted use, and scope boundaries.

Start narrow and measurable

Describe the consuming application and its first useful milestone. A fixed asset list and a maintained discovery service are different requests. Identify required and optional fields, acceptable unavailable states, and the exact historical view needed before discussing broader coverage.

Evaluate delivery patterns

A request-based interface, scheduled export, or stream may fit different workflows. Availability must be confirmed for the project. Define pagination or replay behavior, checkpoint handling, integrity checks, and failure states for the selected pattern instead of assuming all delivery methods are interchangeable.

Confirm commercial terms

Discuss licensed sources, retention, redistribution, model processing, support scope, and any operational requirements. Pricing is by agreed scope; this site does not publish fixed fees, grant access, or accept payment. A requirements conversation should never need a private key, recovery phrase, or production secret.
