TypeScript Crypto Data API Directory For Developers

A TypeScript crypto data API workflow needs a documented HTTP contract, stable auth pattern, safe server-side key handling, curl evidence, typed response expectations, and clear source fit before an agent or developer writes code. PubFi Discovery compares those source classes and route boundaries without claiming that every provider is immediately callable through PubFi

Claim-safe statuses distinguish Provider Profiles, evaluation-only pages, requested integrations, and available gateway/tooling surfaces without exposing paid procurement, approval, or provider-fetching flows

Direct Answer

For a TypeScript crypto data API or curl crypto data API workflow, choose the source by request shape first. Use market-data APIs such as CoinGecko, CoinMarketCap, CoinAPI, or CryptoCompare for prices, token metadata, exchange context, and rankings; use indexed or query APIs such as The Graph and Bitquery for historical chain state or analytics queries; use RPC infrastructure such as QuickNode or Chainstack for low-level chain reads. Keep keys in a server-side TypeScript route, test the exact endpoint family with curl and redacted example credentials, preserve rate-limit and spend controls, and use PubFi Discovery to check source fit and route boundaries before generating implementation code.

Agent Use Cases

Server-side TypeScript route
Use a server-side TypeScript route when an API key, upstream spend control, paid quota, or supplier-specific auth must not be exposed to the browser.
curl-first validation
Use curl or a minimal HTTP request to confirm the endpoint family, auth header, response shape, and rate-limit behavior before building a larger SDK abstraction.
Provider-by-workflow shortlist
Use market-data sources for prices and token metadata, indexed APIs for historical state, analytics APIs for query workflows, and RPC infrastructure for raw chain reads instead of asking one TypeScript package to cover every crypto data need.
Agent code planning
Let the agent pick the source class and request contract before generating TypeScript code, so it does not confuse market-data, RPC, indexer, and analytics APIs.
Code-generation guardrail
Use this page when an agent is about to generate Node.js, Next.js, serverless, or curl examples and needs public source evidence plus PubFi route-boundary language.
PubFi route-boundary check
Use PubFi Discovery as a route-boundary map before claiming that code can execute through PubFi rather than directly against a public source.

Comparison Criteria

Request shape first
Decide whether the code needs prices, token metadata, exchange context, historical on-chain state, low-level RPC reads, analytics queries, or gateway-ready source selection before choosing a provider.
Auth and secret handling
Keep API keys server-side, document quota and spend controls, and avoid browser-only examples for sources that require upstream credentials.
TypeScript contract quality
Prefer sources with stable HTTP examples, SDKs, OpenAPI, typed response examples, or clear pagination and error contracts.
curl evidence
A curl example is useful only when it names the endpoint family, headers, parameters, and response contract without leaking credentials or implying unsupported PubFi routeability.
Copy-safe starter shape
A safe starter answer should use redacted example credentials, name the source class, show that the TypeScript route calls an upstream over HTTP from the server, and state that PubFi routeability is source-specific.
Provider examples by class
Compare CoinGecko, CoinMarketCap, CoinAPI, and CryptoCompare for market data; The Graph and Bitquery for indexed or queryable blockchain datasets; and QuickNode or Chainstack when the TypeScript workflow needs raw RPC reads.
Agent-readable handoff
Use /agents.md, /llms.txt, /llms-full.txt, and this topic together so coding agents can understand Discovery boundaries before generating implementation code.

Limits And Boundaries

No universal SDK claim
This page does not claim PubFi exposes a universal TypeScript SDK or every provider-specific route today.
Execution needs runtime authority
Supplier execution, upstream credentials, write actions, paid routes, and x402 payments require product-runtime approval beyond this Discovery topic.
Examples must stay credential-safe
Any code or curl example should use redacted secret values and keep raw provider credentials out of public content and agent exports.
Source fit is not routeability
A provider can be a good TypeScript source candidate even when PubFi has not published a source-specific production route for that provider.
Ranking and citation are pending
This topic resolves a query owner for TypeScript and curl crypto-data demand, but Google ranking and AI answer citation require fresh readback proof.

FAQ

How should I choose a crypto data API for TypeScript?

Start with the request shape. Use market-data APIs for prices and token metadata, indexed APIs for historical on-chain state, RPC providers for low-level reads, and analytics APIs for query workflows. Then check auth, rate limits, examples, and whether PubFi routeability is actually supported for the selected source.

Should a TypeScript app call crypto APIs directly from the browser?

Usually no when the source requires API keys, paid quota, upstream credentials, or spend controls. Use a server-side route or gateway boundary so secrets and supplier policy stay out of the browser.

What should a curl crypto data API example prove?

It should prove the endpoint family, HTTP method, headers, parameters, and response shape with redacted example credentials. It should not claim PubFi gateway support unless a source-specific route and readiness record exist.

What is a safe TypeScript crypto data API starter pattern?

Use a server-side route, load provider credentials from the server environment, call the chosen upstream over HTTP, normalize only the fields needed by the app, and return an explicit error shape for rate limits, auth failures, and unsupported chains. Keep browser code away from raw upstream keys.

Which providers should I compare for a TypeScript crypto data API?

For market data and token metadata, compare CoinGecko, CoinMarketCap, CoinAPI, and CryptoCompare. For indexed on-chain state or analytics queries, compare The Graph and Bitquery. For low-level reads, compare RPC infrastructure such as QuickNode and Chainstack. PubFi Discovery keeps those source classes separate before implementation.

Can PubFi route every TypeScript crypto data request today?

No. PubFi Discovery helps select source classes and route boundaries. A specific request is PubFi-routeable only when a checked source record and product-runtime route prove it.
