Event Logs API

degraded 3,881 Subscribers

Query any EVM contract's emitted event logs live via the chain's public JSON-RPC, filtered by address, topics and block range, with every log decoded — block, transaction hash, indexed topics and data. A convenience endpoint decodes ERC-20 Transfer events straight into from / to / value. Unlike a single-transaction receipt lookup, this answers "what happened on this contract over this window" — the indexing primitive behind every block explorer, analytics dashboard and on-chain webhook. Pass raw topic hashes or a known event name like Transfer or Approval. Works on any contract, verified or not, across Ethereum, Base, Arbitrum, Optimism, BNB, Polygon and more. Reads straight from the chain; live, short cache only.

NDJSON API

Work with NDJSON / JSON Lines — the one-JSON-value-per-line format used by application and audit logs, streaming and LLM responses, jq, BigQuery, Elasticsearch bulk and many data pipelines. The to-array endpoint parses an NDJSON stream into a regular JSON array; to-ndjson does the reverse, turning a JSON array into NDJSON (one compact value per line); and validate checks every line independently, reporting which lines are valid and the exact parse error for any that are not. Blank lines are ignored. Perfect for log processing, ETL, data import/export and stream debugging. Pure local computation — no key, no third-party service, instant; up to 4 MB via POST. Live, nothing stored. 4 endpoints. Distinct from JSON validation/formatting and from CSV tooling.

Crypto Project Team & Events API

The "who built it and what is on its calendar" view of a cryptocurrency, served from the public CoinPaprika feed. The coin endpoint returns the project's identity and technical profile — market-cap rank, coin-or-token type, whether it is active, the genesis date, development status, consensus / proof type, hashing algorithm, organisation structure, the open-source flag and its industry tags. The team endpoint returns the people behind the project — names and roles such as founders, authors and leads. The events endpoint returns the project's event calendar — conferences, mainnet launches, exchange listings and milestones, each with a date and a link, newest first. This is the project-and-people view of a coin — its team, profile and calendar, not its price — distinct from the price-feed, market and CoinGecko-profile APIs in the catalogue. A coin is a CoinPaprika id (btc-bitcoin); a bare symbol (btc) or name (bitcoin) is resolved automatically to the best-ranked match. Live, no key on the upstream, nothing stored.

Polymarket API

Live prediction-market data from Polymarket, the largest real-money prediction market, via its public Gamma API. On Polymarket people trade shares in the outcome of real-world events, so each market's price is a live, money-backed probability. Get the most active markets, each with its outcomes and their implied probabilities, the best bid and ask, the traded volume and the liquidity. Read one market in full, including its description and resolution date. Pull the biggest events — an event groups related markets, like a championship with one market per team — with their total volume and market count. Get one event with every sub-market and its current probability, the whole field at a glance. Live, no key, nothing stored. Distinct from sports-betting-odds and price-feed APIs — this is Polymarket's money-backed event probabilities and its markets. Perfect for forecasting, trading-signal, news and analytics apps.

Mobilizon API

Live data for Mobilizon, the federated events platform — the open-source ActivityPub alternative to Meetup, Eventbrite and Facebook Events — served straight from Mobilizon's public GraphQL API, no key, nothing cached. The events endpoint searches upcoming public events by keyword and returns each event's title, start and end time, the place (or whether it is online), the organiser, the number of people going, the tags and a link. The event endpoint returns one event in full, including its description. The groups endpoint searches the organising groups and returns each group's name, handle, instance domain, summary and member count. It reads the flagship mobilizon.fr instance, which federates events from across the Mobilizon network. This is the events-and-organisers layer for any community, calendar, social or local app — what is happening, where, and who is organising it. Live from Mobilizon, nothing stored. Distinct from corporate-events and centralised-platform APIs — this is federated grassroots events. 4 endpoints.
