23 tools

• get_overview

  What IoMarkets.tech is and what is built: the ISO 20022 Test Bench, the Data API (market data for AI agents, paid per request over x402), the main pages, and what comes next.

• get_guide

  Step-by-step instructions, with the exact button names, for one task on iomarkets.tech (checking a message, CI, verifying a proof, calling the Data API…). Without a task, lists the tasks.

• explain_term

  A plain-English meaning of a word used on the site (ISO 20022, schema, IBAN, BIC, LEI, ISIN, UETR, CBPR+, x402, signed proof, MCP…) or of an ISO 20022 XML tag abbreviation such as GrpHdr, CdtrAcct or IntrBkSttlmAmt. Without a term, lists the words.

• list_messages

  The ISO 20022 message types and versions the Test Bench checks, with what each is for.

• validate_message

  Check one ISO 20022 XML message (pacs.008.001.08, pacs.009.001.08, pacs.002.001.10, pacs.004.001.09, pain.001.001.09, camt.053.001.08, camt.054.001.08 or seev.031.001.14) against the official base schema, then business rules (check digits, totals, cross-element rules, market…

• explain_issue

  What a Test Bench issue code (such as IBAN_CHECKSUM, BALANCE_MISMATCH or OUT_OF_ORDER) means and how to fix it. Without a code, lists every code.

• list_samples

  The Test Bench sample library: a valid message of each type and broken ones, each with the issue code it raises. Use get_sample for the XML.

• get_sample

  The XML of one sample message from list_samples, to use as a starting point or in tests. Every party and account in it is made up.

• list_data_endpoints

  The Data API routes at https://api.iomarkets.tech, what each returns and its price per call in USDC, with how an AI agent pays (x402 on Algorand mainnet, no account).

• get_api_status

  Whether the Data API at https://api.iomarkets.tech is answering right now, from its /health check.

• estimate_data_api_cost

  What a monthly volume of Data API calls costs at the per-call x402 prices, against the indicative subscription plans. Give calls per month for each route; routes left out count as zero.

• verify_proof

  Check a signed proof (the { payload, signature } JSON a Data API proof route returns): that the ed25519 signature matches the published IoMarkets key, and that its USDC payment is confirmed on Algorand mainnet (looked up on a public indexer IoMarkets does not run).

• explain_execution_request

  Exactly how to call POST https://api.iomarkets.tech/v1/proof/execution, the paid best-execution audit: the body (pair, one of BTC-USDC, ETH-USDC, SOL-USDC, and fills: ts, fill_price, qty, side), the limits (fills per call, how old a fill may be, how close the market trade must…

• verify_execution_report

  Check the whole JSON that POST https://api.iomarkets.tech/v1/proof/execution returned ({ audit, summary, attestation }): that the ed25519 signature matches the published IoMarkets key, that its USDC payment is confirmed on Algorand mainnet (a public indexer IoMarkets does not…

• check_token_contract

  Check a token contract against the Tokenized Asset Map: is it the issuer's own contract for a tokenized fund or security on that chain? Verdicts: official, other-chain (the address is listed, but on another chain), impostor (a listed symbol on this chain, a different contract)…

• list_tokenized_assets

  The securities in the Tokenized Asset Map with their identifiers (FIGI, ISIN where the issuer gives it) and the chains they are tokenized on. Optionally filter by issuer, name, symbol, ticker, ISIN or FIGI.

• get_tokenized_asset

  One Asset Map entry in full: the security, every token contract chain by chain, the issuer sources each comes from, and whether its IoMarkets signature verifies.

• verify_asset_with_issuer

  Fetch the issuer's own sources for one Asset Map entry now (its contracts page, its public API, or its stellar.toml) and confirm every listed contract is still there, so trust needn't rest on IoMarkets.

• list_corporate_actions

  Corporate actions of US-listed companies from their own SEC EDGAR filings (8-Ks of US companies, 6-Ks of foreign private issuers): cash dividends (amount in the stated currency, per share or per ADS, ex, record and payment dates), stock splits, reverse splits and completed…

• holdings_calendar

  For a list of holdings (tickers, CIKs or FIGIs), every ex-date, record date, payment date and effective date in one week, day by day. The week holding `day`, Monday to Sunday; this week by default. Ends with an iCalendar (webcal) subscription URL for those holdings, to give the…

• get_corporate_action

  One event in full: every date and term, the filing and the sentence or table row it came from, tokenized versions in the Asset Map, and the event as an ISO 20022 seev.031.001.14 notification (checked by the Test Bench).

• token_corporate_actions

  For a token contract that the Asset Map lists as a tokenized stock or ETF (such as an xStock): the security it tracks, and that security's dividends, splits and mergers from the corporate actions feed, each with what it does to the token. Answers 'I hold this token; what is…

• get_roadmap

  What IoMarkets.tech has built and is building next, in the same words as iomarkets.org/roadmap.
