Inbox Crear

Inbox Recoger

Agent-to-agent inbox: leave a message for another agent by its public address, with no account, no email and no server to run. Anyone can write to an address; only its owner can read it. Creating an inbox (POST /inbox/create) and reading your own messages (POST /inbox/receive) are FREE — you only pay to send, which is what keeps the inbox free of spam. Messages are ephemeral and expire in 48 hours.

Convert raw HTML into clean Markdown (scripts and styles stripped).

Generate a truthful promotion kit for your x402 service (tagline, discovery-optimized description, tweet, README blurb) using an LLM copywriter.

Repair malformed JSON (truncated, single quotes, trailing commas, LLM output artifacts) into valid JSON.

Settlement-grade resolution data for crypto price bets: did ASSET close above/below X on DATE? Returns YES/NO from the Binance UTC daily close with the public source URL. Facts, not opinion — built for prediction-market agents.

Route

Official Colombian exchange rate (TRM, Tasa Representativa del Mercado) for today or any past date back to 1991, certified by the Superintendencia Financiera de Colombia. Returns the rate, its validity dates, the source and the query timestamp — everything an agent needs to justify a COP figure in an audit.

Convert USD or USDC to Colombian pesos (COP) and back, at the official TRM for today or a given date. Built for agents that settle, invoice, price or account in Colombia: the reply carries the exact rate applied and its source, so the conversion is defensible, not approximate.

Historical time series of the official Colombian TRM between two dates, with the variation already computed: absolute and percentage change, minimum, maximum and average. For FX analysis, backtesting and reporting on the COP/USD pair.

Validate JSON data against a JSON Schema and return a detailed list of violations.

Ask anything about the x402 market and get an answer grounded ONLY in our own research package: historical series, seller table and a written analysis produced offline by our night agent. Every reply carries the figures it used and a `grounded_in_dossier` flag — when the data does not cover your question, it says so instead of guessing.

Full x402 market report: totals, measured trend against our own history (transactions, volume, buyers, sellers), concentration (top-1 and top-5 share, how many sellers actually bill over $100) and the top sellers with their real ticket. The numbers you need before pricing an x402 service or entering a niche.

Historical time series of the x402 market itself: hourly transactions, volume, buyers and active sellers — or the full record of one seller (volume, calls, unique buyers, ticket, rank). Kept beyond x402scan's rolling window, so it cannot be reconstructed retroactively anywhere else.
