Andes Protocol

Use this to decide whether a tender is worth your user's time. Pass tender_id plus company_profile (sector, capabilities, brands, certifications, in the user's words) and/or supplier_id (the user's tax id, e.g. Chilean RUT). Andes checks evidence it holds: the company's terms (with procurement synonyms) in the tender's title, items and description; the supplier's past awards in the same UNSPSC product category; the estimated amount against the supplier's usual award; and whether it already sold to this buyer. Returns fit (strong, possible, weak, insufficient_evidence), relevance_score 0-1, signals (each with status, strength, evidence and source), gaps (what would improve the judgment), the buyer's competition context (average bidders, usual winners) and agent_guidance. Without supplier_id the score is capped: text cannot prove capability. It does not read tender documents yet. Treat it as evidence; the decision is your user's. Access: needs an identified agent key (free, self-service at https://pass.andesprotocol.com).

Use this to learn how a buyer behaves before bidding: what it awarded, to which suppliers, how many bidders its tenders draw (median_bidders, single_bidder_share) and how awards compare with the estimate (median_award_to_estimate). Pass tender_id from search_tenders, or buyer_name, or buyer_id. Built from the buyer's awarded tenders in Open Contracting (OCDS) data; period, sources and computed_at are in each match. An empty matches list comes with a note saying why. Access: needs an identified agent key (free, self-service at https://pass.andesprotocol.com).

Use this before deciding whether a tender is worth pursuing. Pass a tender_id from search_tenders. Returns buyer, description, dates, estimated amount, items, documents, the question deadline and the official source_url, plus agent_guidance: deadlines, questions to ask your user, a checklist of market rules and suggested next calls. If the id is unknown it returns error.code 'not_found': retry with search_tenders using the tender name. Access: open to anonymous agents (rate-limited); a free AndesPass key raises the limit.

Use this to understand a public procurement market before choosing where to bid: the largest awards, supplier concentration (top-3 share, HHI), fastest-growing categories, award versus estimate, single-bidder and direct-award shares, and live open Compras Ágiles with no quote yet, plus amount_anomalies: awards whose recorded amount is out of range (left out of totals, listed to verify at the source). Each signal has a neutral statement, its number, the change against the previous period, an implication for a supplier and suggested_next_calls. Pass category as a UNSPSC code ('42', '4213') or a name ('equipamiento medico'), and period as last_12m (default), a year ('2025') or a quarter ('2025-Q3'). Built from awarded tenders (OCDS), which lag months: every signal states data_as_of. Anonymous agents get one market-wide signal per call. Access: open to anonymous agents (rate-limited); a free AndesPass key raises the limit.

Use this first to find ChileCompra public tenders matching a need. Pass Spanish keywords for best results (e.g. 'firewall', 'notebook', 'ciberseguridad'). Returns only tenders still open for bids (set include_closed=true for history), ordered by match score and then the soonest closing date, each with tender_id, retrieved_at and source_url. Andes adds the synonyms Chilean buyers use (e.g. 'ciberseguridad' also finds 'seguridad informática', 'firewall', 'SOC'): audit.expanded_terms lists them and each result's matched_terms says which term hit. One concept per word is best; accents do not matter. audit.index_last_synced_at and audit.index_open_tenders describe the whole index: zero results with a recent sync means nothing open matches today. Call get_tender_detail before deciding anything. Access: open to anonymous agents (rate-limited); a free AndesPass key raises the limit.

Use this to size up a supplier, your user's own company or a competitor: what it won, from which buyers, in which categories, how many bidders it beat (competition_when_winning: read median_bidders first, framework agreements with hundreds of bidders skew the average), and, when bidder lists are published, its win rate and most frequent competitors. Pass supplier_id (tax id such as a Chilean RUT, or the supplier_id seen in buyer_history) or supplier_name. Suppliers are grouped by legal identifier; built from awarded tenders in Open Contracting (OCDS) data. An empty matches list comes with a note saying why. Access: needs an identified agent key (free, self-service at https://pass.andesprotocol.com).
