Guide for developing with near-api-js v7 - the JavaScript/TypeScript library for NEAR blockchain interaction. Use when: (1) building apps that interact with NEAR blockchain, (2) creating/signing transactions, (3) calling smart contracts, (4) managing accounts and keys, (5) working with NEAR RPC API, (6) handling FT/NFT tokens on NEAR, (7) using NEAR cryptographic operations (KeyPair, signing), (8) converting between NEAR units (yocto, gas), (9) gasless/meta transactions with relayers, (10) NEP-413 message signing for authentication, (11) storage deposit management for FT contracts. Triggers on any NEAR blockchain development tasks.

What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 159 tok |
| When the agent uses it | The SKILL.md instructions | 3,854 tok |
| Only if opened | 7 bundled files (37 KB) | varies |
Until it is used, near-api-js costs about 8.6× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 95 skills from internet-court/internet-court-skill would load 8,864 tokens of descriptions. Skills vs MCP study
